00:00:00,720 --> 00:00:03,960
Hello and welcome back Shark. 
Here is to another episode of 

2
00:00:03,960 --> 00:00:06,200
Deep Dives with sharks. 
My name is Alex. 

3
00:00:06,200 --> 00:00:08,920
I am the host here. 
I have not wandered off into the

4
00:00:08,920 --> 00:00:11,600
ocean to pet a shark, at least 
not yet. 

5
00:00:12,240 --> 00:00:15,040
There's still time. 
So there's shark safety news 

6
00:00:15,040 --> 00:00:17,240
episode as that's where the 
rotation goes. 

7
00:00:17,720 --> 00:00:20,000
Since most of you guys are here 
for the sharks, I'm going to do 

8
00:00:20,000 --> 00:00:23,480
a few episodes with safety and 
news, Buffer movie review, 

9
00:00:23,480 --> 00:00:25,200
Aquarium review, different 
episode. 

10
00:00:25,880 --> 00:00:27,520
Then do a few episodes with 
three sharks. 

11
00:00:27,760 --> 00:00:30,000
To be clear, there's going to be
like 1 buffer episode. 

12
00:00:30,000 --> 00:00:32,080
I'm not going to like just throw
a bunch of random episodes in 

13
00:00:32,080 --> 00:00:34,720
the middle and then talk about 
sharks more, but something to 

14
00:00:34,720 --> 00:00:36,880
kind of split it up. 
I'm trying to give everyone a 

15
00:00:36,880 --> 00:00:39,640
little bit of what they like. 
Unless you like all of it, then 

16
00:00:39,640 --> 00:00:42,240
in which case you get all of it.
So when, when? 

17
00:00:42,720 --> 00:00:45,400
But to stay at the date on 
everything that is Deep Dives 

18
00:00:45,400 --> 00:00:48,640
with Sharks, hit the follow 
button on Spotify, Apple Music, 

19
00:00:48,680 --> 00:00:52,160
Instagram, Twitch, YouTube, 
Amazon Music, or anywhere else 

20
00:00:52,160 --> 00:00:54,640
that you get your podcast at 
Deep Dives with Sharks. 

21
00:00:55,120 --> 00:00:58,640
Now we're going to jump kind of 
right into the shark that we 

22
00:00:58,640 --> 00:01:02,080
have for today, which is going 
to be the Port Jackson shark. 

23
00:01:02,280 --> 00:01:05,960
And these sharks are one that 
pop into my mind frequently, but

24
00:01:05,960 --> 00:01:08,440
I don't know a lot about them. 
They're absolutely beautiful and

25
00:01:08,440 --> 00:01:09,680
I was really hyped to do this 
episode. 

26
00:01:10,200 --> 00:01:13,000
So to start at the Port Jackson 
shark is part of the hetero 

27
00:01:13,000 --> 00:01:16,920
Dante Day family, which is hard 
to say, which only includes 

28
00:01:16,920 --> 00:01:20,080
other bullhead sharks. 
So they could have just called 

29
00:01:20,080 --> 00:01:22,640
it the Bullhead shark family, 
but that'd be a little too easy.

30
00:01:23,280 --> 00:01:28,680
They typically grow up to 1.65 
meters or 5.5 feet long, which 

31
00:01:28,680 --> 00:01:30,920
is a little shorter than me, so 
I'll take that as a win. 

32
00:01:31,520 --> 00:01:34,000
They have an interesting 
coloration that has a yellowish 

33
00:01:34,000 --> 00:01:37,080
brown base with brown stripes 
that form throughout their body,

34
00:01:37,480 --> 00:01:39,200
but it comes in varying 
patterns. 

35
00:01:40,000 --> 00:01:42,440
They'll also have some white on 
them, often around the ridges 

36
00:01:42,440 --> 00:01:46,320
that sit above their eyes. 
They have a long tall head that 

37
00:01:46,320 --> 00:01:49,960
leads into a brown snout. 
Their eyes are high set and have

38
00:01:49,960 --> 00:01:52,520
ridges that are placed above 
them that trail back towards 

39
00:01:52,520 --> 00:01:55,360
their gills. 
Their pectoral fins lay flat on 

40
00:01:55,360 --> 00:01:58,840
their side and they appear to be
rather large for their size. 

41
00:01:59,040 --> 00:02:01,920
They have two dorsal fins with 
the second being slightly 

42
00:02:01,920 --> 00:02:05,160
smaller than the first. 
The dorsal fins also have spines

43
00:02:05,160 --> 00:02:07,520
on the front because they liked 
what the spiny dogfish was doing

44
00:02:07,520 --> 00:02:09,840
with that look. 
Porcupines are also a pretty big

45
00:02:09,840 --> 00:02:13,360
fan, so good to know they got a 
club now. 

46
00:02:13,360 --> 00:02:15,440
Their nose and mouth are rather 
freaky. 

47
00:02:16,280 --> 00:02:18,040
I was not prepared for their 
nostrils. 

48
00:02:18,040 --> 00:02:21,680
Face straight down and in 
between them is a row of teeth. 

49
00:02:22,800 --> 00:02:25,520
The front teeth are sharp while 
the back teeth are more blunt, 

50
00:02:25,520 --> 00:02:29,160
which helps with crushing. 
Their mouth is also about as 

51
00:02:29,160 --> 00:02:30,560
wide. 
It goes pretty much as about the

52
00:02:30,560 --> 00:02:33,640
width of their head, but the 
teeth are only in the middle 

53
00:02:33,640 --> 00:02:36,240
kind of in between those 
nostrils and the the teeth are 

54
00:02:36,240 --> 00:02:37,080
just right. 
That's weird. 

55
00:02:37,880 --> 00:02:40,640
So straight up looking at a poor
Jackson shark from above, they 

56
00:02:40,640 --> 00:02:41,880
look like a distinguished 
gentleman. 

57
00:02:41,880 --> 00:02:43,160
And then you get a view from 
below. 

58
00:02:43,160 --> 00:02:45,520
When it's the mouth of a clown 
from a horror movie. 

59
00:02:45,520 --> 00:02:48,080
It's honestly terrifying. 
It's rather weird that they 

60
00:02:48,080 --> 00:02:50,560
would go with this. 
I don't quite understand why 

61
00:02:50,560 --> 00:02:53,960
they'd want to do that, but you 
know, to each their own. 

62
00:02:54,960 --> 00:02:58,480
Now it's time to move away from 
the freakiness of them a bit and

63
00:02:58,480 --> 00:03:01,560
also tell you that they are only
found around Australia, but it's

64
00:03:01,560 --> 00:03:03,600
believed that they are also 
around New Zealand. 

65
00:03:03,600 --> 00:03:06,160
Although the only specimen that 
was said to be caught in New 

66
00:03:06,160 --> 00:03:09,840
Zealand waters was not properly 
documented and scientists cannot

67
00:03:09,840 --> 00:03:11,840
confirm a proper collection 
location. 

68
00:03:12,320 --> 00:03:14,280
Australia's confirmed New 
Zealand strong. 

69
00:03:14,280 --> 00:03:16,520
Maybe Canada? 
No, they're not really close to 

70
00:03:16,520 --> 00:03:19,160
Canada, sorry. 
But you can find them in the 

71
00:03:19,160 --> 00:03:22,080
Ripley's Aquarium of Canada. 
In America we have them in 

72
00:03:22,080 --> 00:03:24,200
Newport Aquarium and the 
Tennessee Aquarium. 

73
00:03:24,640 --> 00:03:27,320
I'd also like to real quick note
that when I was looking this up,

74
00:03:27,640 --> 00:03:30,440
Google listed the Newport 
Aquarium under both America and 

75
00:03:30,440 --> 00:03:33,160
Canada and I looked into it 
thinking, oh, maybe it's on the 

76
00:03:33,160 --> 00:03:34,640
border or something neat like 
that. 

77
00:03:35,600 --> 00:03:38,400
No, it's in Kentucky, which 
isn't really near the border at 

78
00:03:38,400 --> 00:03:41,200
all. 
So, you know, it's kind of 

79
00:03:41,200 --> 00:03:44,120
middle of the country ish. close
enough to Canada, right? 

80
00:03:44,880 --> 00:03:48,040
But anyway, back on topic. 
They're mostly found around 

81
00:03:48,040 --> 00:03:51,280
southern Australia, venturing as
far north as the York Sound. 

82
00:03:51,560 --> 00:03:53,720
But marine biologists have 
labeled those reports as 

83
00:03:53,760 --> 00:03:56,720
dubious, which is a pretty 
polite way of saying whoever 

84
00:03:56,720 --> 00:03:59,800
reported this is lying. 
But they're usually found around

85
00:03:59,800 --> 00:04:02,720
Queensland, around southern 
Australia, and coming up into 

86
00:04:02,720 --> 00:04:07,520
the Central Coast of WA, which, 
another quick sidebar, I didn't 

87
00:04:07,520 --> 00:04:12,040
realize y'all literally named 
the western part of Australia WA

88
00:04:12,040 --> 00:04:15,360
and caught it a day. 
Like, Americans saw we had a lot

89
00:04:15,360 --> 00:04:16,640
of space and went, you know 
what? 

90
00:04:16,640 --> 00:04:20,320
Texas, California, Florida, 
Alaska, going to need y'all to 

91
00:04:20,320 --> 00:04:23,200
cover some real ground here. 
But Australians just went, yeah,

92
00:04:23,320 --> 00:04:27,280
it's Australian, it's W WA. 
You know, you got to respect it.

93
00:04:27,280 --> 00:04:28,760
That's actually pretty, pretty 
great. 

94
00:04:28,960 --> 00:04:31,240
Although you should have put it 
on the eastern side just to mess

95
00:04:31,240 --> 00:04:34,360
with everyone, be kind of funny.
We're going to go to WA. 

96
00:04:34,360 --> 00:04:35,240
Where is it? 
The east? 

97
00:04:35,240 --> 00:04:37,160
Great. 
Anyway, sorry, this is going to 

98
00:04:37,160 --> 00:04:40,640
be 90 minutes if I don't stop. 
The Port Jackson shark is a 

99
00:04:40,680 --> 00:04:43,640
bottom dwelling shark and is 
often found in depths of less 

100
00:04:43,640 --> 00:04:47,080
than 100 meters, which is 330 
feet for those of us who can't 

101
00:04:47,080 --> 00:04:49,240
use the metric system because 
our country is weird. 

102
00:04:49,480 --> 00:04:52,200
It's a triple shot at the United
States, Liberia and Myanmar. 

103
00:04:52,240 --> 00:04:55,960
So let's get together guys. 
Now the poor Jackson shark will 

104
00:04:55,960 --> 00:04:59,680
usually be in shallower waters 
of 100 meters, 330 feet or less,

105
00:04:59,960 --> 00:05:03,160
but can explore further into 
depths of 275 meters. 

106
00:05:03,280 --> 00:05:07,240
Now real quick to have a little 
fun, I'm going to pause here, 

107
00:05:08,040 --> 00:05:10,640
see if anyone can convert that 
meters to feet themselves. 

108
00:05:12,280 --> 00:05:14,600
Anyone. 
Bueller. 

109
00:05:16,080 --> 00:05:20,200
Bueller. 
It's going to be 902 feet. 

110
00:05:20,200 --> 00:05:22,800
So let me know if you all got 
that in the comments because I 

111
00:05:22,920 --> 00:05:25,720
definitely didn't Now also, you 
could have paused it there to 

112
00:05:25,720 --> 00:05:27,360
give yourself more time as well 
if you wanted. 

113
00:05:27,800 --> 00:05:30,120
So maybe next time we'll find 
out. 

114
00:05:31,280 --> 00:05:33,920
But the Port Jackson sharks, 
they tend to like rocks around 

115
00:05:33,920 --> 00:05:37,280
their habitat kind of like they 
really do like a good boulder, I

116
00:05:37,280 --> 00:05:39,080
got to say. 
But they aren't opposed to 

117
00:05:39,080 --> 00:05:41,560
sandy, muddy or grass bed sea 
floors. 

118
00:05:41,560 --> 00:05:43,560
They're not too picky as other 
sharks are. 

119
00:05:44,480 --> 00:05:47,240
Now during the day, these sharks
will hang out in caves or other 

120
00:05:47,240 --> 00:05:50,920
areas that have a flat floor 
shielding from the current so 

121
00:05:50,920 --> 00:05:52,720
they can rest. 
Because these boyos are 

122
00:05:52,720 --> 00:05:56,120
nocturnal, their nocturnal 
behaviors have been on display 

123
00:05:56,120 --> 00:06:00,080
in captivity as well as they 
were seen moving more and at the

124
00:06:00,080 --> 00:06:03,200
night time especially the most 
between when it gets dark and 

125
00:06:03,200 --> 00:06:05,120
midnight. 
But then after midnight, their 

126
00:06:05,120 --> 00:06:06,520
activity would begin to 
diminish. 

127
00:06:06,800 --> 00:06:09,000
So it's kind of like how humans 
wake up and we're a little 

128
00:06:09,000 --> 00:06:12,280
groggy, but then we get a little
bit more energy and then once it

129
00:06:12,280 --> 00:06:14,440
hits about 3 or 4 in the 
afternoon, we tend to kind of 

130
00:06:14,440 --> 00:06:17,160
crash a little bit and need a 
little pick me up or a little 

131
00:06:17,160 --> 00:06:19,200
nap. 
Same thing happens with Port 

132
00:06:19,200 --> 00:06:21,320
Jackson sharks. 
Their activity diminishes after 

133
00:06:21,320 --> 00:06:24,560
midnight. 
Now, the Port Jackson shark also

134
00:06:24,560 --> 00:06:27,720
migrates annually, which is a 
little bit confusing for a shark

135
00:06:27,720 --> 00:06:30,400
that hangs out around 1 country 
and continent, which you got to 

136
00:06:30,400 --> 00:06:31,800
put a little respect on 
Australia's name. 

137
00:06:31,800 --> 00:06:34,240
It's both. 
So they migrate from the coastal

138
00:06:34,240 --> 00:06:37,000
waters to bays and harbors along
the coastline. 

139
00:06:37,280 --> 00:06:41,480
So not quite thousands of miles,
but the salmon swim upstream, 

140
00:06:41,480 --> 00:06:44,280
and that's a migration. 
So it's not so much the distance

141
00:06:44,280 --> 00:06:46,960
as much as doing it repeatedly 
at a certain time or for a 

142
00:06:46,960 --> 00:06:49,400
certain reason. 
And these guys tend to do that 

143
00:06:49,400 --> 00:06:51,760
for popping reasons, which is 
neat. 

144
00:06:52,680 --> 00:06:55,360
But something really interesting
is that the Port Jackson shark 

145
00:06:55,360 --> 00:06:59,200
migration was tracked using Tri 
axial accelerometers. 

146
00:06:59,200 --> 00:07:02,200
That is such a hard word to say 
for someone that never has to 

147
00:07:02,200 --> 00:07:06,720
say that phrase. 
Tri axial accelerometers that 

148
00:07:06,720 --> 00:07:09,560
also gauge the sharks movement. 
I was trying to figure out a 

149
00:07:09,560 --> 00:07:12,600
great way to explain these in my
own words, but looking on the 

150
00:07:12,600 --> 00:07:14,880
Wikipedia, they kind of nailed 
it just by saying they're very 

151
00:07:14,880 --> 00:07:17,520
similar to like Fitbit or 
smartwatches that track your 

152
00:07:17,520 --> 00:07:20,880
movement the same way. 
So just imagine we kind of 

153
00:07:20,880 --> 00:07:24,400
hooked up a Fitbit to a shark 
and called it a day, but it 

154
00:07:24,400 --> 00:07:27,080
allowed us to track where they 
went, how far they went, things 

155
00:07:27,080 --> 00:07:30,400
like that. 
Now the Port Jackson shark have 

156
00:07:30,400 --> 00:07:33,640
5 gills, similar to many sharks,
but for some reason, the first 

157
00:07:33,640 --> 00:07:36,880
gill slit only has a single row 
of gill filament, while the 

158
00:07:36,880 --> 00:07:39,680
others contain double rows. 
Researchers are not quite sure 

159
00:07:39,680 --> 00:07:43,320
why the first has less, but the 
sharks also have a respiratory 

160
00:07:43,320 --> 00:07:45,720
accessory called a spherical 
that sits behind their eye. 

161
00:07:46,080 --> 00:07:49,400
So that's where they tend to 
breathe behind their eye, which 

162
00:07:49,400 --> 00:07:53,640
is interesting, but they also 
have lamellae which help. 

163
00:07:53,880 --> 00:07:56,520
It's where the oxygen goes to be
used essentially. 

164
00:07:56,520 --> 00:07:59,160
Which to go in a little bit more
in depth about that, the 

165
00:07:59,160 --> 00:08:01,840
lamellae use arteries, which I 
don't even know if I'm 

166
00:08:01,840 --> 00:08:03,760
pronouncing that right. 
They use arteries which carry 

167
00:08:03,760 --> 00:08:06,880
blood away from the heart to the
rest of the body to deliver 

168
00:08:06,880 --> 00:08:10,320
oxygen throughout our shark. 
But these arteries push blood in

169
00:08:10,320 --> 00:08:12,400
the opposite direction of the 
flow of water. 

170
00:08:12,400 --> 00:08:14,680
So when the water is coming into
the gills, the blood is flowing 

171
00:08:14,680 --> 00:08:17,760
in the opposite direction, which
does not mean out of the shark. 

172
00:08:17,760 --> 00:08:21,040
It just means like if the gills 
are going backwards or the flow 

173
00:08:21,040 --> 00:08:23,240
of water is going backwards, the
blood is pumping towards the 

174
00:08:23,240 --> 00:08:27,360
head, if that makes sense. 
Now excuse me. 

175
00:08:27,360 --> 00:08:30,840
The whole point of this is to 
help oxygen dissolve into the 

176
00:08:30,840 --> 00:08:33,520
blood because they tend to live 
near the bottom of the ocean. 

177
00:08:33,520 --> 00:08:35,640
They like the sea floor. 
So if they're going to be 

178
00:08:35,640 --> 00:08:39,080
staying on the sea floor, then 
they don't have quite as much 

179
00:08:39,080 --> 00:08:41,240
oxygen as the upper water 
column. 

180
00:08:41,240 --> 00:08:43,960
So they need to get as much 
oxygen into their gills as they 

181
00:08:43,960 --> 00:08:45,880
can. 
So having this resistance or 

182
00:08:45,880 --> 00:08:49,720
keeping the water and blood kind
of in the same spot will help to

183
00:08:49,720 --> 00:08:52,680
get the blood diffused into or 
the oxygen diffused into the 

184
00:08:52,680 --> 00:08:54,680
blood. 
So that way the shark can then 

185
00:08:54,680 --> 00:08:56,000
put the oxygen throughout its 
body. 

186
00:08:56,600 --> 00:08:58,400
That was very technical and very
sciency. 

187
00:08:59,520 --> 00:09:01,840
That might be a little bit 
complicated for some listeners. 

188
00:09:01,840 --> 00:09:03,840
So if you didn't quite 
understand that, don't worry. 

189
00:09:05,120 --> 00:09:08,320
Eventually we'll get the middle 
school, high school, college bio

190
00:09:08,320 --> 00:09:11,000
and it'll click somewhere there 
because it did not click for me 

191
00:09:11,000 --> 00:09:13,680
until much later. 
But hey, we got here. 

192
00:09:13,800 --> 00:09:15,280
I can explain it somewhat. 
That's exciting. 

193
00:09:15,760 --> 00:09:20,000
But anyway, so another neat 
thing about the Port Jackson 

194
00:09:20,000 --> 00:09:24,080
shark is that they can eat and 
breathe at the same time feet. 

195
00:09:24,080 --> 00:09:26,840
Many sharks cannot. 
You'll often see shark gills 

196
00:09:26,840 --> 00:09:29,600
flare when they're eating, 
causing them to have to inhale 

197
00:09:29,600 --> 00:09:32,160
and then eat. 
One of the greatest examples is 

198
00:09:32,160 --> 00:09:34,480
great whites. 
When you see them eating on like

199
00:09:34,480 --> 00:09:36,480
Shark Week, you'll see them go 
to Turd and you'll see their 

200
00:09:36,480 --> 00:09:40,520
Garrett gills just flare out. 
So yeah, Port Jackson sharks 

201
00:09:40,520 --> 00:09:42,960
don't have to do that. 
They're just built different and

202
00:09:42,960 --> 00:09:44,480
they can eat and breathe all at 
once. 

203
00:09:44,480 --> 00:09:46,600
So they'll be able to eat and 
then hold their breath. 

204
00:09:47,120 --> 00:09:51,240
Now I do keep thinking about how
I need to wrap this shark up 

205
00:09:51,520 --> 00:09:54,920
because at this point in my 
research, I was on three hours 

206
00:09:54,920 --> 00:09:59,320
of research and I was on page 4 
already, which usually it it's 

207
00:09:59,320 --> 00:10:03,840
not that much, but they just 
there's so many cool things 

208
00:10:03,840 --> 00:10:06,720
about this shark. 
And with that being said, they 

209
00:10:06,720 --> 00:10:10,400
have AJ shaped stomach. 
So like the letter J it, it 

210
00:10:10,400 --> 00:10:14,440
hooks Now, food can pass through
really easily. 

211
00:10:14,920 --> 00:10:18,160
But if something that is not 
food tries to pass through, the 

212
00:10:18,240 --> 00:10:21,280
shark is able to either cough it
up or if they just can't get it 

213
00:10:21,280 --> 00:10:25,520
out, they'll just turn their 
stomach inside out casually. 

214
00:10:25,840 --> 00:10:28,360
You know, which I wonder if it's
kind of more like when you're 

215
00:10:28,360 --> 00:10:31,560
surprised by a burp that comes 
out or if it's like on command, 

216
00:10:31,680 --> 00:10:34,000
just oh, excuse me, I appear to 
have turned my stomach inside 

217
00:10:34,000 --> 00:10:36,960
out, which it's not really great
for dinner parties. 

218
00:10:37,360 --> 00:10:39,000
But I mean, even if they did 
that in front of you, you'd 

219
00:10:39,000 --> 00:10:43,000
really only find sea urchins, 
mollusk fishes and other 

220
00:10:43,000 --> 00:10:45,480
crustaceans because that's 
pretty much their entire diet. 

221
00:10:45,920 --> 00:10:47,400
Now. 
Their favorite though, is Black 

222
00:10:47,400 --> 00:10:49,120
Sea urchins. 
They have been seen to go a 

223
00:10:49,120 --> 00:10:51,760
little bit nutty about those, so
they do like Black Sea urchins 

224
00:10:51,760 --> 00:10:54,160
the most. 
Their sharp front teeth help to 

225
00:10:54,160 --> 00:10:57,480
catch and eat fish that have the
little softer bits, while 

226
00:10:57,480 --> 00:11:01,040
mollusks and urchins that have 
the harder bits get worn down by

227
00:11:01,040 --> 00:11:03,760
the blunt back teeth. 
So their teeth are designed to 

228
00:11:03,760 --> 00:11:06,640
help with really all of their 
dietary needs. 

229
00:11:08,600 --> 00:11:12,080
Adult Port Jackson sharks often 
group up to rest in caves, often

230
00:11:12,080 --> 00:11:14,760
based on their size and boys 
club versus Girls Club. 

231
00:11:15,120 --> 00:11:17,440
But the kids aren't all right 
and prefer to be solitary 

232
00:11:17,440 --> 00:11:18,960
because they have trust issues 
or something. 

233
00:11:18,960 --> 00:11:22,040
I'm not quite sure. 
But evidently juvenile Port 

234
00:11:22,040 --> 00:11:24,960
Jackson sharks can be trained 
very easily by aquarium staff in

235
00:11:24,960 --> 00:11:28,560
captivity as they respond well 
to LED lights, bubbles and 

236
00:11:28,560 --> 00:11:30,960
sounds. 
So really any stimulus they 

237
00:11:30,960 --> 00:11:34,760
respond to now they also learn 
by watching other sharks. 

238
00:11:35,080 --> 00:11:38,000
So I'm kind of disappointed that
there aren't, that they aren't 

239
00:11:38,000 --> 00:11:41,240
near the open ocean because I 
think it would be amazing to see

240
00:11:41,240 --> 00:11:44,040
one of these goofballs breaching
after watching great white do 

241
00:11:44,040 --> 00:11:45,360
it. 
Just be kind of funny just 

242
00:11:45,360 --> 00:11:47,640
seeing like a little small guys 
flopping around. 

243
00:11:48,080 --> 00:11:51,120
But anyway, now these sharks 
also pose no threat to humans, 

244
00:11:51,120 --> 00:11:54,040
although they should be 
absolutely feared because in 

245
00:11:54,040 --> 00:11:58,000
2011, a man was bit by 1 and it 
was so, so horrible. 

246
00:11:58,400 --> 00:12:01,400
The shark was latched onto his 
calf and the man swam to shore, 

247
00:12:01,600 --> 00:12:04,200
wasn't even bleeding. 
The teeth did not Pierce his 

248
00:12:04,200 --> 00:12:06,520
skin. 
They're pretty harmless and 

249
00:12:06,520 --> 00:12:08,640
humans tend not bother them. 
They're really only caught as 

250
00:12:08,640 --> 00:12:11,200
bycatch and not caught for sport
or really anything else. 

251
00:12:11,520 --> 00:12:15,800
So they sometimes bite us very 
rarely, and when they do they 

252
00:12:15,800 --> 00:12:18,360
don't really hurt so. 
But don't go mess with poor 

253
00:12:18,360 --> 00:12:20,600
Jackson sharks. 
So there's going to be 1 that'll

254
00:12:20,600 --> 00:12:24,000
mess you up now. 
Also, because of humans and poor

255
00:12:24,000 --> 00:12:27,160
Jackson sharks not really 
beefing, they're listed as Least

256
00:12:27,160 --> 00:12:30,880
Concern, but they do face a high
egg mortality rate. 

257
00:12:31,440 --> 00:12:34,600
They do lay eggs, which is 
really cool, but evidently as 

258
00:12:34,600 --> 00:12:37,600
high as 89.1% of the eggs won't 
hatch. 

259
00:12:37,880 --> 00:12:40,800
And it's kind of a sad thing to 
end on for the Port Jackson 

260
00:12:40,800 --> 00:12:43,280
shark. 
So I feel a more fun thing would

261
00:12:43,280 --> 00:12:45,440
be that their eggs are spiral 
shaped. 

262
00:12:45,440 --> 00:12:47,240
They kind of look like a big old
drill bit. 

263
00:12:48,040 --> 00:12:50,000
There's a big spiral. 
So they're kind of fun looking. 

264
00:12:50,000 --> 00:12:52,280
So definitely worth looking into
that. 

265
00:12:52,840 --> 00:12:55,600
But that is what I have for the 
Port Jackson shark. 

266
00:12:56,480 --> 00:12:58,440
Of course, if you have any 
questions, any corrections for 

267
00:12:58,440 --> 00:13:01,520
me or anything of that nature, 
you can send it over to me in 

268
00:13:01,520 --> 00:13:04,080
any of the DMS or in the 
comments, anything like that. 

269
00:13:04,680 --> 00:13:08,800
But moving on to our safety bit 
we have what if I find a shark 

270
00:13:08,800 --> 00:13:12,960
egg, which this information I 
got from sharktrust.org, which 

271
00:13:12,960 --> 00:13:16,600
is an amazing resource. 
Now, First off, you're more 

272
00:13:16,600 --> 00:13:19,240
likely to find a shark egg 
during low tide. 

273
00:13:19,640 --> 00:13:21,880
It's also when many things get 
washed ashore, but you could 

274
00:13:21,880 --> 00:13:25,400
still find one during high tide.
Now, the website noted that you 

275
00:13:25,400 --> 00:13:27,840
should let someone know where 
you are going and what you're 

276
00:13:27,840 --> 00:13:30,200
going to be doing, especially if
you're going shark teeth or 

277
00:13:30,200 --> 00:13:32,680
capsule hunting. 
It's just a great idea in case 

278
00:13:32,680 --> 00:13:34,880
something goes wrong. 
Nobody really knows what could 

279
00:13:34,880 --> 00:13:37,640
happen. 
Me and Goalie tend to like to 

280
00:13:37,640 --> 00:13:40,600
walk on beaches at night and 
when we were in California we 

281
00:13:40,600 --> 00:13:43,640
were walking over on Laguna 
Beach and did not realize that 

282
00:13:43,640 --> 00:13:47,440
when high tide comes in that the
water can go up to the entire 

283
00:13:47,440 --> 00:13:49,640
beach. 
And thankfully we noticed that 

284
00:13:49,880 --> 00:13:52,240
the rock we were sitting on, the
water was getting closer and 

285
00:13:52,240 --> 00:13:55,440
closer to it and figured, you 
know, we should probably get out

286
00:13:55,440 --> 00:13:57,200
of here before we suddenly get 
trapped here. 

287
00:13:58,000 --> 00:13:59,840
It's a good idea. 
So thankfully everything was OK 

288
00:13:59,840 --> 00:14:02,920
because you're paying attention.
But if we weren't, we could have

289
00:14:02,920 --> 00:14:05,200
gotten stuck there and then 
someone wanted needed to come 

290
00:14:05,200 --> 00:14:07,680
save us or something like that. 
Not pretty great. 

291
00:14:08,160 --> 00:14:10,240
So just make sure you people 
know where you are so that way 

292
00:14:10,240 --> 00:14:11,800
if something happens, they can 
come find you. 

293
00:14:12,920 --> 00:14:16,240
Now you'll also want to have a 
stick or some kind of poker just

294
00:14:16,240 --> 00:14:19,440
to ensure that you won't get bit
stung aggressively cuddled by 

295
00:14:19,440 --> 00:14:20,720
something that didn't want you 
to move. 

296
00:14:20,720 --> 00:14:23,760
Its Heidi little seaweed spot. 
It's better to be safe than 

297
00:14:23,760 --> 00:14:26,440
sorry. 
You're also most likely not to 

298
00:14:26,440 --> 00:14:29,120
realize that you are looking at 
a shark egg as they're meant to 

299
00:14:29,120 --> 00:14:31,560
blend in with their environment.
So if they're hooked onto that 

300
00:14:31,560 --> 00:14:34,440
seaweed that washed ashore, it 
won't have a quest marker over 

301
00:14:34,440 --> 00:14:35,800
it. 
With the mission save a shark 

302
00:14:35,800 --> 00:14:38,520
and a timer, it'll most likely 
just look like another leaf, but

303
00:14:38,520 --> 00:14:41,960
in a Port Jackson sharks case 
it'll have a really twisty leaf 

304
00:14:41,960 --> 00:14:43,320
to it. 
So at least a little bit of 

305
00:14:43,320 --> 00:14:46,000
distinction there. 
Now it could also be an empty 

306
00:14:46,000 --> 00:14:47,720
egg case. 
So you'll want to check to see 

307
00:14:47,720 --> 00:14:49,320
if there's an embryo still 
inside. 

308
00:14:49,640 --> 00:14:51,920
You can do this by having really
any light source nearby. 

309
00:14:51,920 --> 00:14:53,960
So if it's the daytime sun works
great. 

310
00:14:54,840 --> 00:14:56,680
Having the light behind it helps
a lot. 

311
00:14:56,680 --> 00:14:59,160
But sometimes it's really 
obvious that there's an embryo 

312
00:14:59,160 --> 00:15:01,840
still in there. 
So you don't need like a high 

313
00:15:01,840 --> 00:15:05,840
beam Searchlight to look for it.
Sometimes you just simply need 

314
00:15:05,840 --> 00:15:07,720
to shine a phone light behind it
and then you're good. 

315
00:15:08,720 --> 00:15:10,800
If it's empty you can put it 
back where you found it or 

316
00:15:10,800 --> 00:15:13,520
something like that. 
Some people feel like collecting

317
00:15:13,520 --> 00:15:16,200
shark teeth is wrong and shark 
egg casings as well. 

318
00:15:16,720 --> 00:15:19,840
I'm torn because I have shark 
teeth that I found but I don't 

319
00:15:19,840 --> 00:15:21,240
take shells home or anything 
anymore. 

320
00:15:21,240 --> 00:15:25,680
I'm just not that into it. 
I also just want the teeth and 

321
00:15:25,680 --> 00:15:28,160
none of the sharks near me lay 
eggs so I'm not going to find a 

322
00:15:28,160 --> 00:15:30,840
case or I'm not going to just 
grab a baby hammerhead and take 

323
00:15:30,840 --> 00:15:32,760
it home. 
That's a horrible idea. 

324
00:15:33,360 --> 00:15:35,840
Now I did try to look into it to
give you guys more information 

325
00:15:35,840 --> 00:15:39,040
to figure out what to do with a 
hatched egg and Google keeps 

326
00:15:39,040 --> 00:15:41,600
calling me a piece of garbage 
for taking an unhatched egg 

327
00:15:41,600 --> 00:15:44,760
home, which I have not and isn't
even what I was asking. 

328
00:15:44,760 --> 00:15:48,000
So now all my search results 
results are how could you you 

329
00:15:48,000 --> 00:15:50,200
absolute monster and I don't 
need this. 

330
00:15:50,200 --> 00:15:52,760
So if anyone would like to 
enlighten me on if it's OK or 

331
00:15:52,760 --> 00:15:55,520
not to take sharks home, shark 
eggs not sharks, don't take 

332
00:15:55,520 --> 00:15:59,200
sharks home, shark eggs home, 
feel free to do so below. 

333
00:16:00,040 --> 00:16:03,200
But also I wanted to point out 
that while doing the research by

334
00:16:03,200 --> 00:16:06,840
impulsivity had gotten the best 
of me because I got caught up on

335
00:16:06,840 --> 00:16:09,080
a bullet point on the website, 
did not finish reading the 

336
00:16:09,080 --> 00:16:12,560
article before I started looking
into other things, and started 

337
00:16:12,560 --> 00:16:15,960
being called garbage by Google. 
Only for the next bullet point 

338
00:16:15,960 --> 00:16:19,640
directly under the one that I 
got stuck on to say empty egg 

339
00:16:19,640 --> 00:16:22,480
cases are not known to have any 
secondary purpose. 

340
00:16:22,720 --> 00:16:25,960
They don't break down to form 
sand or offer habitat as some 

341
00:16:25,960 --> 00:16:28,800
shells do for hermit crabs. 
They also don't decompose to 

342
00:16:28,800 --> 00:16:35,080
form part of the strand line. 
Take him home. 

343
00:16:35,080 --> 00:16:36,320
I don't care. 
I hate it here. 

344
00:16:36,320 --> 00:16:39,560
I swear I spent like 20 minutes 
Googling. 

345
00:16:40,240 --> 00:16:42,920
Are you allowed to take hatched 
shark eggs home? 

346
00:16:43,160 --> 00:16:46,120
And the entire thing is like, do
not take animals from wildlife. 

347
00:16:47,320 --> 00:16:49,920
Yeah I know I'm not going to do 
that. 

348
00:16:50,320 --> 00:16:53,800
Why are you yelling at me? 
So yeah, I guess it's OK. 

349
00:16:53,800 --> 00:16:56,040
I don't know. 
Don't try to do your own 

350
00:16:56,040 --> 00:16:58,120
research as well. 
Don't base everything that you 

351
00:16:58,120 --> 00:17:00,720
do off of what I say. 
I try to give good information, 

352
00:17:00,720 --> 00:17:02,360
but I probably get some of it 
wrong. 

353
00:17:02,360 --> 00:17:05,000
So please also look into it if 
you're thinking about doing 

354
00:17:05,000 --> 00:17:08,160
anything like that. 
But I thought it was funny. 

355
00:17:08,160 --> 00:17:10,440
I got yelled at by Google only 
for the next bullet point to 

356
00:17:10,440 --> 00:17:14,880
give me my answer. 
But back on topic, if you are to

357
00:17:14,880 --> 00:17:17,560
find an egg case that is not 
empty, you want to try to get it

358
00:17:17,560 --> 00:17:20,480
back in the water now. 
This does not mean you want to 

359
00:17:20,520 --> 00:17:22,400
absolutely throw it as far as 
you can. 

360
00:17:22,480 --> 00:17:25,319
There's a good chance it's going
to get damaged or simply wash 

361
00:17:25,319 --> 00:17:28,440
back ashore again. 
You're not Jaden Daniels during 

362
00:17:28,440 --> 00:17:30,400
a 75 yard bomb to Terry 
Mclaurin. 

363
00:17:30,600 --> 00:17:32,720
It's just a little shark and 
it's delicate. 

364
00:17:32,720 --> 00:17:35,160
So you want to place it past the
waves and anchor it to 

365
00:17:35,160 --> 00:17:37,800
something. 
Now most eggs aren't going to 

366
00:17:37,800 --> 00:17:39,880
have too many things you can 
utilize, you just got to kind of

367
00:17:40,280 --> 00:17:42,520
put it somewhere. 
But skate eggs, which looks 

368
00:17:42,520 --> 00:17:44,880
similar, they have horns on 
them, so you can weigh it down 

369
00:17:44,880 --> 00:17:47,480
by the horns. 
Cat shark eggs tend to have 

370
00:17:47,480 --> 00:17:50,440
these long thingies on them 
called tendrils that you can 

371
00:17:50,440 --> 00:17:53,200
just tie to something, but 
others just wedging it gently 

372
00:17:53,200 --> 00:17:56,480
between some rocks will do. 
Now you need to be careful not 

373
00:17:56,480 --> 00:18:00,400
to smash, squish, or damage the 
egg in any way as they are 

374
00:18:00,400 --> 00:18:02,440
malleable. 
So they can be a little squishy 

375
00:18:02,440 --> 00:18:05,240
and a little movable, pliable, 
anything like that. 

376
00:18:06,320 --> 00:18:09,400
But they're kind of similar to 
like chicken eggs, how they're 

377
00:18:09,400 --> 00:18:12,920
rather fragile, so they're not 
made of steel. 

378
00:18:13,120 --> 00:18:15,760
Chicken eggs break pretty easy. 
Shark eggs can also break rather

379
00:18:15,760 --> 00:18:18,760
easily, but a little bit harder.
Now you don't have to worry 

380
00:18:18,760 --> 00:18:21,200
about other sharks being 
territorial of their eggs like 

381
00:18:21,200 --> 00:18:23,720
birds are. 
Sharks often have babies and 

382
00:18:23,720 --> 00:18:25,240
then they go about their lives 
without the baby. 

383
00:18:25,240 --> 00:18:27,840
They just, it happens. 
They, they just abandoned 

384
00:18:27,840 --> 00:18:30,600
immediately. 
Now, many sharks like being in 

385
00:18:30,600 --> 00:18:33,760
the same areas as their 
offspring, but would definitely 

386
00:18:33,760 --> 00:18:35,840
fight their own child if it 
meant that they can get the food

387
00:18:35,840 --> 00:18:39,360
that the kid was going for. 
It's a me versus them mentality.

388
00:18:40,280 --> 00:18:42,120
Now. 
They won't come bite you because

389
00:18:42,120 --> 00:18:44,200
you're holding an egg. 
It's not like a bird's going to 

390
00:18:44,200 --> 00:18:45,480
attack you or anything like 
that. 

391
00:18:45,480 --> 00:18:47,320
Or chickens pack people when 
they're trying to grab their 

392
00:18:47,320 --> 00:18:50,000
eggs. 
Sharks don't care that take the 

393
00:18:50,000 --> 00:18:52,280
egg, eat it. 
They don't care, don't eat a 

394
00:18:52,280 --> 00:18:53,600
shark egg. 
It would not be good. 

395
00:18:54,000 --> 00:18:58,280
Now, something to consider is 
what is around where you're 

396
00:18:58,280 --> 00:19:00,800
going to put the shark egg. 
Now, of course, you don't need 

397
00:19:00,800 --> 00:19:02,560
to find the most perfect spot 
ever. 

398
00:19:02,560 --> 00:19:05,120
Sometimes it'll do. 
But you want to find a place 

399
00:19:05,120 --> 00:19:09,560
where it'll be wedged nicely, 
not come loose too easily. 

400
00:19:10,600 --> 00:19:12,880
But also make sure that you 
don't wedge it in such a way 

401
00:19:12,880 --> 00:19:15,120
that the baby shark can't like 
escape and then it's kind of 

402
00:19:15,120 --> 00:19:16,560
stuck between the egg and a 
rock. 

403
00:19:17,280 --> 00:19:19,520
But also as well, you want to 
make sure that the egg isn't 

404
00:19:20,000 --> 00:19:22,720
going to get dislodged and wash 
back ashore. 

405
00:19:23,280 --> 00:19:26,000
And you also want to see if 
there's a horn shark nearby 

406
00:19:26,000 --> 00:19:27,600
that's just eating other shark 
eggs. 

407
00:19:27,920 --> 00:19:31,000
They do like to do that. 
I probably wouldn't leave the 

408
00:19:31,000 --> 00:19:32,760
egg in that buffet. 
That's just not going to be 

409
00:19:32,760 --> 00:19:34,480
helpful. 
Now, I'm not saying going a 

410
00:19:34,480 --> 00:19:38,200
whole cross country adventure to
put a shark egg back in the 

411
00:19:38,200 --> 00:19:42,440
water. 
But I mean, hey, 30 feet a 

412
00:19:42,440 --> 00:19:44,760
different way, right? 
But you don't want to put it 

413
00:19:44,760 --> 00:19:46,640
somewhere where it can get 
damaged or where it can get 

414
00:19:46,640 --> 00:19:48,120
washed away. 
You want to try to anchor it 

415
00:19:48,120 --> 00:19:51,080
down nicely. 
But of course, once again, if 

416
00:19:51,080 --> 00:19:53,200
you're trying, you're doing your
best and that's all we ask. 

417
00:19:53,880 --> 00:19:56,320
Now, I do mention this every 
safety segment, but don't put 

418
00:19:56,320 --> 00:19:59,360
yourself in danger to save a 
shark or a shark egg. 

419
00:19:59,360 --> 00:20:03,360
If it's low tide and you can get
the egg into a nice outcropping 

420
00:20:03,360 --> 00:20:06,800
without having a wave slam you 
into a rock, go for it. 

421
00:20:07,240 --> 00:20:09,480
If it's hurricane force winds, 
it's downpouring. 

422
00:20:09,480 --> 00:20:12,800
There's 500 foot waves. 
Don't go try to save a shark egg

423
00:20:12,800 --> 00:20:15,080
that that that's in God's hands 
at that point. 

424
00:20:15,600 --> 00:20:18,000
Also if you can see a shark egg 
in those conditions. 

425
00:20:19,040 --> 00:20:21,160
Might as well as quit your job. 
You know, you're a superhero at 

426
00:20:21,160 --> 00:20:24,800
that point and the world need to
so go use your supervision to go

427
00:20:24,800 --> 00:20:27,440
save somebody. 
All right, That's I don't know 

428
00:20:27,440 --> 00:20:29,520
how you'd see it in that 
condition, but my goodness. 

429
00:20:29,880 --> 00:20:32,400
But one thing I want to end on 
here is that Shark Trust is a 

430
00:20:32,400 --> 00:20:35,520
great resource to use and learn 
more about sharks, how to help 

431
00:20:35,520 --> 00:20:37,320
them, how to protect them around
the world. 

432
00:20:37,680 --> 00:20:41,120
I highly recommend checking them
out and any other source I've 

433
00:20:41,120 --> 00:20:44,400
used for the safety segments. 
All of them are pretty great 

434
00:20:44,400 --> 00:20:47,880
when it comes to answering your 
questions and going on with 

435
00:20:47,880 --> 00:20:50,280
that. 
But of course we've come to the 

436
00:20:50,760 --> 00:20:53,560
long-awaited part that I have 
not talked about in a long 

437
00:20:53,560 --> 00:20:55,800
while. 
It's the news. 

438
00:20:57,000 --> 00:20:59,440
So the first news story that I 
haven't got 2 for you today. 

439
00:20:59,680 --> 00:21:03,120
The first one is about 
cuttlefish and that the 

440
00:21:03,120 --> 00:21:05,880
cuttlefish ink may overwhelm 
shark's sense of smell. 

441
00:21:05,880 --> 00:21:09,280
And this is by sciencenews.org. 
So we're getting sciency today. 

442
00:21:09,880 --> 00:21:12,840
Sharks like eating cuttlefish 
sometimes and the cuttlefish got

443
00:21:13,000 --> 00:21:15,400
pretty tired of it. 
Now their main defense is to 

444
00:21:15,400 --> 00:21:18,000
shoot ink at its attacker, 
similar to how squid do. 

445
00:21:18,600 --> 00:21:21,080
But their second defense is 
having a massive bone that takes

446
00:21:21,080 --> 00:21:23,760
up like all of their body, but 
sharks still get through. 

447
00:21:23,760 --> 00:21:25,720
Technically it's a shell, but 
then whatever. 

448
00:21:26,720 --> 00:21:28,960
So the cuttlefish realized they 
have to evolve to get these 

449
00:21:28,960 --> 00:21:31,280
sharks away from them and 
decided that they're going to 

450
00:21:31,280 --> 00:21:34,600
have ink that is full of melanin
that binds to smell receptors in

451
00:21:34,600 --> 00:21:38,000
a shark's nose. 
Now the smell receptors are what

452
00:21:38,000 --> 00:21:39,720
grant us the range that we can 
smell. 

453
00:21:40,120 --> 00:21:44,880
Now humans have about 850 smell 
receptors, so we can smell a lot

454
00:21:44,880 --> 00:21:47,520
of different things. 
Fun fact, humans can smell rain 

455
00:21:48,040 --> 00:21:51,240
and wet dirt the best. 
Don't know why but we can. 

456
00:21:52,720 --> 00:21:55,160
It's from when we were nomads 
when we had to figure out where 

457
00:21:55,160 --> 00:21:57,440
water was. 
Anyway, I can go and do a whole 

458
00:21:57,440 --> 00:21:58,880
rant about this, but we're going
to stay focused. 

459
00:21:58,880 --> 00:22:01,360
So we have 8:50. 
It helps us to smell a lot. 

460
00:22:01,600 --> 00:22:05,560
But sharks, they have 43 so they
get a lot less. 

461
00:22:05,560 --> 00:22:09,440
But the scientists believe that 
these are fine-tuned for things 

462
00:22:09,440 --> 00:22:12,720
such as blood stress signals, 
other things fish have, and also

463
00:22:12,720 --> 00:22:15,800
just kind of first survival. 
So they can also smell things 

464
00:22:15,800 --> 00:22:18,160
that tell them they need to get 
out of there immediately. 

465
00:22:18,760 --> 00:22:21,280
Now, the melanin in the 
cuttlefish ink binds the 

466
00:22:21,280 --> 00:22:25,480
receptors blocking other scents.
But on top of that, there's a 

467
00:22:25,480 --> 00:22:28,160
chemical compound in the ink 
that makes sharks run off. 

468
00:22:28,200 --> 00:22:32,840
So having that fine tune, this 
kind of a disadvantage when, 

469
00:22:33,120 --> 00:22:35,200
which means that when the shark 
can't smell other things at the 

470
00:22:35,200 --> 00:22:38,320
time and they can only smell the
smell that they don't like, then

471
00:22:38,320 --> 00:22:41,000
they just kind of cause them to 
keep hightailing it away from 

472
00:22:41,000 --> 00:22:43,360
the cuttlefish, which is a 
pretty smart move by evolution 

473
00:22:43,360 --> 00:22:45,040
there because that just keeps 
going. 

474
00:22:45,520 --> 00:22:48,480
Which that also means that this 
compound could be used in shark 

475
00:22:48,480 --> 00:22:51,080
repellent or to help keep sharks
away from certain areas, 

476
00:22:51,360 --> 00:22:53,800
Although that is rather 
controversial because it can 

477
00:22:53,800 --> 00:22:56,400
disturb the ecosystem by driving
sharks elsewhere. 

478
00:22:56,720 --> 00:22:59,360
And more testing we need to be 
done to see how it could be used

479
00:22:59,440 --> 00:23:03,280
if it can be used without 
damaging the entire ecosystem 

480
00:23:04,280 --> 00:23:06,120
because they also don't know how
to affect other fish too. 

481
00:23:06,120 --> 00:23:10,240
So something to think about. 
But the next one that I have is 

482
00:23:10,240 --> 00:23:13,760
largest shark ever tagged by 
research group named contender 

483
00:23:14,040 --> 00:23:15,560
is swimming off of North 
Florida. 

484
00:23:15,560 --> 00:23:17,280
And this is reported by CBS 
News. 

485
00:23:17,680 --> 00:23:21,880
Now, one thing that irks me 
about these article titles is 

486
00:23:21,880 --> 00:23:26,400
that they tell you quite 
literally everything in the 

487
00:23:26,400 --> 00:23:33,080
headline. 
Like I don't know why they give 

488
00:23:33,080 --> 00:23:36,120
you the whole story in the 
headline, but I don't it anyway,

489
00:23:36,520 --> 00:23:38,600
I'm not a journalist person, so 
I don't know. 

490
00:23:38,720 --> 00:23:41,840
I just talked about sharks. 
Now the largest shark ever 

491
00:23:41,840 --> 00:23:44,000
tagged is hanging out in North 
Florida. 

492
00:23:44,400 --> 00:23:47,480
Contender, a male great white 
shark was tagged by O search on 

493
00:23:47,480 --> 00:23:51,640
January 17th, 2025 around 
southern Georgia when he decided

494
00:23:51,640 --> 00:23:54,280
that the coast was lame and he 
wanted to head out to see a bit 

495
00:23:54,280 --> 00:23:56,720
more, but then realized he 
didn't buy his lady shark some 

496
00:23:56,720 --> 00:23:58,360
Mickey ears. 
So he had to come back this way 

497
00:23:58,360 --> 00:24:00,480
because you know Disney World's 
right around the corner, might 

498
00:24:00,480 --> 00:24:04,160
as well head that way. 
Now Contender is 13.8 feet, 

499
00:24:04,160 --> 00:24:09,400
which is 4.2 meters in length 
and about 1653 lbs which is 

500
00:24:09,840 --> 00:24:15,480
749.8kg for the weight. 
Now O Search was able to take 

501
00:24:15,480 --> 00:24:17,440
some samples from Contender 
before releasing him. 

502
00:24:17,840 --> 00:24:20,600
This will help to see any 
genetic code, anything like 

503
00:24:20,600 --> 00:24:24,440
that, any DNA to see possibly 
how he got so big, how healthy 

504
00:24:24,440 --> 00:24:29,200
he is, etcetera, etcetera. 
But on top of that, the tag that

505
00:24:29,200 --> 00:24:32,040
they put on him will last five 
years to track his location. 

506
00:24:32,040 --> 00:24:34,840
But unfortunately not many other
metrics on him. 

507
00:24:35,000 --> 00:24:36,560
Now. 
You can also follow along with 

508
00:24:36,560 --> 00:24:38,440
Contender. 
You can download the O Search 

509
00:24:38,440 --> 00:24:42,040
app or follow it online and you 
can see other sharks, sea 

510
00:24:42,040 --> 00:24:43,800
turtles, whales that they have 
tagged. 

511
00:24:44,200 --> 00:24:46,480
I had a favorite shark, his name
was Pico. 

512
00:24:46,840 --> 00:24:49,320
He was a Mako and that was 
tagged near Texas. 

513
00:24:49,680 --> 00:24:53,760
I must emphasize the word had as
I still love him very much, but 

514
00:24:53,760 --> 00:24:57,480
his tag has not pinged since 
2021 and that was AZ ping, which

515
00:24:57,480 --> 00:24:59,760
means that it communicate with a
satellite but it couldn't 

516
00:24:59,760 --> 00:25:02,600
provide a location. 
So I hope that the satellite tag

517
00:25:02,600 --> 00:25:05,680
just ended and he's out there 
eating lots of yummy things and 

518
00:25:05,680 --> 00:25:09,000
doing all the great breeches. 
But that's what I have for this 

519
00:25:09,000 --> 00:25:10,520
episode. 
I want to thank you all once 

520
00:25:10,520 --> 00:25:12,600
again for listening and being 
here and hanging out. 

521
00:25:13,640 --> 00:25:16,360
Commenter DM your favorite shark
fact and I may share a couple of

522
00:25:16,360 --> 00:25:19,280
them on the start of the next 
episode, because I usually start

523
00:25:19,280 --> 00:25:20,800
my episodes by rambling about 
nothing. 

524
00:25:20,840 --> 00:25:23,080
So might as well share some fun 
shark facts. 

525
00:25:23,560 --> 00:25:25,640
You can also follow along on 
Instagram for more updates. 

526
00:25:25,640 --> 00:25:29,040
I tend to update that the one 
that one the most deep dives 

527
00:25:29,040 --> 00:25:30,600
with sharks. 
But of course, you got twitch, 

528
00:25:30,600 --> 00:25:34,120
the tap link everything else 
that you can utilize to make 

529
00:25:34,120 --> 00:25:37,200
sure you find me wherever you 
can send in any comments, 

530
00:25:37,200 --> 00:25:38,760
questions or anything of the 
sort. 

531
00:25:39,040 --> 00:25:41,800
And of course, give us a rating 
on Spotify, Apple Music, 

532
00:25:41,800 --> 00:25:43,920
anywhere you listen to your 
podcast, because ratings 

533
00:25:43,920 --> 00:25:46,880
comments, everything of the sort
do help to spread this even 

534
00:25:46,880 --> 00:25:48,600
more. 
So I thank you all for hanging 

535
00:25:48,600 --> 00:25:50,880
out listening and I will see you
in the next one. 

536
00:25:51,080 --> 00:25:51,480
Take care.
