1 00:00:08,560 --> 00:00:12,200 You're listening to deep dives of the Sharks the Shark Podcast 2 00:00:12,200 --> 00:00:15,760 focused on shark species, shark safety both for you and the 3 00:00:15,760 --> 00:00:18,280 sharks, and news in the past couple weeks. 4 00:00:18,720 --> 00:00:21,360 Sit back, relax. It's time to take a dive. 5 00:00:25,550 --> 00:00:28,630 Hello, and welcome back Shark. Here's to another episode of 6 00:00:28,630 --> 00:00:31,350 Deep Dives with Sharks. I am the host here. 7 00:00:31,350 --> 00:00:34,470 My name is Alex, and I appreciate your patience as 8 00:00:34,470 --> 00:00:36,550 always. I'd also like to thank you all 9 00:00:36,550 --> 00:00:39,310 for your feedback from the social media posts that I made. 10 00:00:39,310 --> 00:00:43,030 I'm going to try to implement as many things as possible, but I 11 00:00:43,030 --> 00:00:45,670 can't really promise that I'll get to do all of it, as some 12 00:00:45,670 --> 00:00:49,330 things aren't entirely doable. A lot of things do depend on the 13 00:00:49,330 --> 00:00:51,530 amount of time that I have, which is why I'll probably end 14 00:00:51,530 --> 00:00:54,090 up going back and going over some of the older episodes in 15 00:00:54,090 --> 00:00:56,490 the future to update information and just make sure that I 16 00:00:56,490 --> 00:00:58,050 thoroughly went through that species. 17 00:00:58,690 --> 00:01:02,450 Also, that's the time constraint is why I'm usually late, but 18 00:01:03,250 --> 00:01:05,930 there are sometimes where the shark just doesn't have a whole 19 00:01:05,930 --> 00:01:09,290 lot of info on it. So like the Carolina Hammerhead, 20 00:01:09,720 --> 00:01:12,400 the only things that I could find on that were that they go 21 00:01:12,400 --> 00:01:15,400 into bays and estuaries and the Carolinas that breed and pup, if 22 00:01:15,400 --> 00:01:17,720 I remember correctly. So they really only got a tiny 23 00:01:17,720 --> 00:01:19,280 shout out in the Hammerhead episode. 24 00:01:19,600 --> 00:01:22,120 So sometimes there's just not a whole lot out there. 25 00:01:22,680 --> 00:01:24,840 I will try to implement a lot of the things that you guys 26 00:01:24,840 --> 00:01:27,480 mentioned and if you have any other ideas or things that you'd 27 00:01:27,480 --> 00:01:31,320 like to see me do, feel free to hit me up on the socials, deep 28 00:01:31,320 --> 00:01:35,600 dives with sharks on Instagram and on Twitter or X it is going 29 00:01:35,600 --> 00:01:40,730 to be deep dive sharks. So real quick before we get into 30 00:01:40,730 --> 00:01:43,850 the shark for this week, I do have a correction corner to go 31 00:01:43,850 --> 00:01:45,890 over. I do want to issue a quick 32 00:01:45,890 --> 00:01:49,490 apology as in the last episode I said that people who shark fin 33 00:01:49,490 --> 00:01:51,530 are quote lame as hell and quote. 34 00:01:51,890 --> 00:01:54,530 But this was because I've always looked at that issue through a 35 00:01:54,530 --> 00:01:57,930 privileged lens and I've had other options for work and to 36 00:01:57,930 --> 00:01:59,810 make a living. But I was listening to 37 00:01:59,810 --> 00:02:01,810 Sharkpedia which I recommend all of you do. 38 00:02:02,330 --> 00:02:04,650 They pointed out that some people in the world don't have 39 00:02:04,650 --> 00:02:07,730 another option for protein or to make a living, so the alternate 40 00:02:07,730 --> 00:02:10,180 is just starving. So now that I know that I would 41 00:02:10,180 --> 00:02:13,700 like to adjust my statement to those who have a means and 42 00:02:13,700 --> 00:02:16,500 options to make a living and doing something different and 43 00:02:16,500 --> 00:02:18,380 still choose to participate in shark finning. 44 00:02:18,820 --> 00:02:20,620 They're lame as hell, so I'll stand by that. 45 00:02:21,140 --> 00:02:24,900 But I also did get a question from someone which I will say 46 00:02:24,900 --> 00:02:27,820 that I would like to turn this into questions slash correction 47 00:02:27,820 --> 00:02:29,340 corner. So if you guys have questions 48 00:02:29,340 --> 00:02:32,360 you want me to answer on the podcast, feel free to once again 49 00:02:32,360 --> 00:02:34,720 send them into any of my social media and I'll try to update 50 00:02:34,720 --> 00:02:37,560 that on here. But one of my friends, recent 51 00:02:37,560 --> 00:02:41,200 engaged man and recent new dad Austin, who asked if humans are 52 00:02:41,200 --> 00:02:44,240 born with all their adult teeth packed in their face, do sharks 53 00:02:44,240 --> 00:02:46,760 just have billions of teeth packed in their jaws? 54 00:02:47,120 --> 00:02:50,080 And the answer is dependent on species and the type of tooth. 55 00:02:50,960 --> 00:02:54,680 So the way that humans are born is that you have your gums and 56 00:02:54,680 --> 00:02:57,570 then after a couple months you start growing in your teeth. 57 00:02:57,570 --> 00:03:00,010 And then of course the years down the line, those baby teeth 58 00:03:00,010 --> 00:03:03,290 start falling out and then your adult teeth come through and 59 00:03:03,290 --> 00:03:05,690 take the place in the roots there and then poke through 60 00:03:05,690 --> 00:03:08,010 everything like that. We we all have lost teeth 61 00:03:08,010 --> 00:03:09,730 before. Most likely if you haven't it, 62 00:03:09,730 --> 00:03:13,010 it's going to happen. But sharks are rather different. 63 00:03:13,010 --> 00:03:16,330 They're born with their entire set of teeth off the jump and 64 00:03:16,530 --> 00:03:18,530 then they have a couple sets of teeth behind that. 65 00:03:18,530 --> 00:03:20,850 So that's where the rows of teeth come in and they kind of 66 00:03:20,850 --> 00:03:22,850 have what's known as like a tooth conveyor belt. 67 00:03:23,200 --> 00:03:26,560 So as a tooth falls out, a tooth just moves forward, once again 68 00:03:26,560 --> 00:03:28,480 depending on the species. So like great whites, a tooth 69 00:03:28,480 --> 00:03:30,800 will move forward, cookie cutters an entire row. 70 00:03:31,360 --> 00:03:35,880 But from there, they just kind of keep growing teeth as their 71 00:03:35,880 --> 00:03:38,200 life goes on. They have specialized cells that 72 00:03:38,200 --> 00:03:41,080 will grow those teeth for them. So that way they can just keep 73 00:03:41,080 --> 00:03:45,000 that tooth conveyor belt moving and get the teeth going forward. 74 00:03:45,440 --> 00:03:48,360 But some sharks, like the cookie cutter shark will often swallow 75 00:03:48,400 --> 00:03:50,840 the row of teeth they just lost to help get more calcium to 76 00:03:50,840 --> 00:03:53,720 produce more teeth in the future since their diet isn't really 77 00:03:53,720 --> 00:03:56,040 calcium rich. Now salt fish, which are 78 00:03:56,040 --> 00:03:59,040 technically a type of ray, are interesting because their teeth 79 00:03:59,080 --> 00:04:00,920 on their rostrum aren't replaceable. 80 00:04:00,920 --> 00:04:04,820 So if a salt fish loses its tooth on its rostrum, it won't 81 00:04:04,820 --> 00:04:08,660 regrow it, but it's all shark I believe can replace its teeth. 82 00:04:08,900 --> 00:04:10,980 Now this is where it gets a little tricky and complicated. 83 00:04:10,980 --> 00:04:13,460 So the short answer is that sharks grow teeth throughout 84 00:04:13,460 --> 00:04:16,060 their whole life, but humans? They're born with the sets of 85 00:04:16,060 --> 00:04:18,899 teeth that they will have. Now I'd like to add at the end 86 00:04:18,899 --> 00:04:23,980 of this, a very load bearing I believe, because I look this all 87 00:04:23,980 --> 00:04:27,020 up and I believe I have accurate information, but it also got 88 00:04:27,020 --> 00:04:30,500 very technical and I'm not sure if I understood it completely. 89 00:04:30,820 --> 00:04:33,820 So this is me trying to get the information out correctly, but 90 00:04:33,900 --> 00:04:37,100 I'm also adding that maybe also look into it yourself a little 91 00:04:37,100 --> 00:04:39,420 bit, just to be sure. But of course if someone does 92 00:04:39,420 --> 00:04:42,780 know better, please let me know. I'll be more than happy to 93 00:04:42,900 --> 00:04:44,300 update this in the Corrections corner. 94 00:04:44,300 --> 00:04:46,180 Every corrections corner is going to be about teeth now I 95 00:04:46,180 --> 00:04:48,940 swear. But a quick shout out to Shark 96 00:04:48,940 --> 00:04:52,420 Pedia, Some of the information that I get is from them and I've 97 00:04:52,420 --> 00:04:53,820 also been binging their podcasts. 98 00:04:53,820 --> 00:04:55,340 I'm absolutely hooked. It's amazing. 99 00:04:55,820 --> 00:04:58,020 And that's where I learned that cookie cutter sharks tend to eat 100 00:04:58,020 --> 00:05:00,020 their teeth. So that's a nice little fun 101 00:05:00,020 --> 00:05:04,050 fact, but on to the shark for this week. 102 00:05:04,290 --> 00:05:07,210 Now this one was probably one of the most requested sharks I've 103 00:05:07,210 --> 00:05:11,850 had ever since I started putting those up on the podcast 104 00:05:11,850 --> 00:05:14,730 episodes. Pretty much almost every episode 105 00:05:14,730 --> 00:05:19,770 has this shark and also it's been sent to my DMS on the 106 00:05:19,770 --> 00:05:21,650 social media. But we're going to go over the 107 00:05:21,650 --> 00:05:24,250 Greenland shark. So I think this one got 108 00:05:24,410 --> 00:05:27,080 recommended probably, I think it got to the double digits. 109 00:05:27,080 --> 00:05:30,160 It was probably at least 10/15/20, maybe 30 times. 110 00:05:30,160 --> 00:05:33,840 It was so many. But this one, they're also known 111 00:05:33,840 --> 00:05:36,120 as the Gray shark, which there are quite a few of those. 112 00:05:36,120 --> 00:05:37,640 I feel like every shark I go over. 113 00:05:37,640 --> 00:05:39,280 Their other nickname is the Gray shark. 114 00:05:39,480 --> 00:05:41,320 It's also known as the Gary shark. 115 00:05:41,400 --> 00:05:44,400 And in the Greenlandic language, which I don't know how to 116 00:05:44,400 --> 00:05:46,880 pronounce the name of the Greenlandic language because I'm 117 00:05:46,880 --> 00:05:49,440 not going to try, because I'm going to try to say the name of 118 00:05:49,440 --> 00:05:51,800 it in Greenlandic, which I'm probably going to mess up. 119 00:05:51,800 --> 00:05:57,120 And I really do apologize, but it's the Equallusak, it's 120 00:05:57,120 --> 00:06:02,360 EQALUSSUAQ. There's a lot of QS in there, 121 00:06:02,360 --> 00:06:06,120 and I do not know how to pronounce AQ after an A, so I 122 00:06:06,120 --> 00:06:10,160 apologize. But Greenland sharks are closely 123 00:06:10,160 --> 00:06:13,840 related to Pacific and Southern Sleeper Sharks, and the three of 124 00:06:13,840 --> 00:06:16,280 them are often misidentified as each other. 125 00:06:17,240 --> 00:06:21,600 They're rather large, growing the sizes of 2.4 to 7 meters or 126 00:06:21,600 --> 00:06:26,280 7.9 to 23 feet long, which is quite a range, and they weigh 127 00:06:26,280 --> 00:06:32,480 around 400 to 1400 KG or 880 to 3090 pounds. 128 00:06:32,950 --> 00:06:35,990 They typically are found in frigid waters of the Arctic and 129 00:06:35,990 --> 00:06:38,710 tend to spend time around the northern Atlantic, around 130 00:06:38,710 --> 00:06:42,310 Canada, northern Europe, and of course found around Greenland. 131 00:06:42,510 --> 00:06:45,110 But they've been found in a lot of weird places, including deep 132 00:06:45,110 --> 00:06:48,070 in the ocean off the coast of North Carolina, and one was in 133 00:06:48,070 --> 00:06:50,710 the Gulf of Mexico, which I assume it just wanted to tan, 134 00:06:50,710 --> 00:06:55,150 although it was rather deep. But Speaking of that color, they 135 00:06:55,150 --> 00:06:57,750 are usually pale Gray or brownish black with an 136 00:06:57,750 --> 00:07:00,790 occasional spots or darker stripe along their back. 137 00:07:01,250 --> 00:07:04,530 They are rather round and have short rounded snout as well as 138 00:07:04,530 --> 00:07:07,290 very small fins. Their eyes and gill slits are 139 00:07:07,290 --> 00:07:10,370 also rather small, so big body, small everything else. 140 00:07:10,890 --> 00:07:15,530 They typically reside between the surface and 1500 meters or 141 00:07:15,530 --> 00:07:18,770 4900 feet depending on the temperature of the water. 142 00:07:18,770 --> 00:07:20,970 So the ones that are further South are rather deep. 143 00:07:21,210 --> 00:07:23,330 The ones in the freezing waters tend to be closer to the 144 00:07:23,330 --> 00:07:26,450 surface. The sharks migrate frequently, 145 00:07:26,770 --> 00:07:29,750 but instead of traveling from one location to another, it's 146 00:07:29,750 --> 00:07:32,510 more of a migration between depths as the temperatures and 147 00:07:32,510 --> 00:07:35,310 food source changes. And Speaking of food, they do 148 00:07:35,310 --> 00:07:37,830 have an interesting variety of food that you probably would be 149 00:07:37,830 --> 00:07:40,830 surprised about unless you yourself are a Greenland shark 150 00:07:40,830 --> 00:07:44,150 or know more about them. They eat mostly fish, but also 151 00:07:44,150 --> 00:07:48,630 consume smaller sharks, seals, skate eels, herring, flounder, 152 00:07:48,710 --> 00:07:52,230 lumpfish, cod and others. Their stomach contents have 153 00:07:52,230 --> 00:07:54,950 shown that these sharks are active hunters despite only 154 00:07:54,950 --> 00:08:00,190 moving around 1.22 kilometers or an hour or .76 miles an hour 155 00:08:00,190 --> 00:08:05,190 with bursts up to 2.6 kilometers per hour or 1.6 mph. 156 00:08:05,190 --> 00:08:08,870 So they are flying. Researchers have found reindeer, 157 00:08:08,870 --> 00:08:11,430 moose and seals in their stomachs and believe that since 158 00:08:11,430 --> 00:08:14,390 these animals all swim faster than the Greenland shark, these 159 00:08:14,510 --> 00:08:17,070 sharks must be ambushed. Predators catching seals while 160 00:08:17,070 --> 00:08:19,990 sleeping and moose and reindeer while taking a rest while 161 00:08:19,990 --> 00:08:22,940 swimming. They also did find an entire 162 00:08:22,940 --> 00:08:25,580 reindeer in the stomach of a Greenland shark. 163 00:08:26,260 --> 00:08:28,900 The Greenland shark is able to sneak up on prey by blending 164 00:08:28,900 --> 00:08:31,500 into the ocean around them and not creating a lot of 165 00:08:31,500 --> 00:08:33,860 disturbance in the water. Through their slow movement, 166 00:08:34,299 --> 00:08:36,620 they're also able to create a lot of suction when opening 167 00:08:36,620 --> 00:08:40,179 their buccal cavity, which from what I understood is essentially 168 00:08:40,179 --> 00:08:42,500 just their mouth and beginning of their throat. 169 00:08:42,980 --> 00:08:45,620 Once again, there's a lot of technical terms in here that are 170 00:08:45,620 --> 00:08:49,060 scientific and I once again and not really a scientist, I am 171 00:08:49,060 --> 00:08:51,680 more of a fan of sharks that made this. 172 00:08:51,960 --> 00:08:54,160 But when they open up their mouth and get that suction 173 00:08:54,160 --> 00:08:56,560 going, that helps to stop prey from escaping. 174 00:08:56,560 --> 00:08:58,080 So it's sort of like a tractor beam. 175 00:08:58,960 --> 00:09:01,280 They did find that entire reindeer in the stomach, which 176 00:09:01,280 --> 00:09:05,040 is what gave them that theory that they get the the suction 177 00:09:05,040 --> 00:09:08,040 there and that's how the sharks hunt since it has not been 178 00:09:08,040 --> 00:09:11,040 observed. Now, Greenland sharks are 179 00:09:11,040 --> 00:09:14,240 believed to be the longest living vertebrate on Earth, as 180 00:09:14,240 --> 00:09:17,880 their lifespan is believed to be around 300 to 500 years. 181 00:09:18,360 --> 00:09:21,920 Now, researchers are able to use radiocarbon dating of the 182 00:09:21,920 --> 00:09:24,880 crystals in the lens of the shark's eyes to determine their 183 00:09:24,880 --> 00:09:31,640 age, and in 2016 a specimen was dated to be 392 ± 120 years old, 184 00:09:31,640 --> 00:09:34,640 which is still insanely old. So to break that down a little 185 00:09:34,640 --> 00:09:38,240 bit, they believe that the shark was born between fifteen O 4 and 186 00:09:38,240 --> 00:09:42,720 1744, which would put it older than the United States which 187 00:09:42,720 --> 00:09:47,580 claimed independence in 1776. But if you base America's age 188 00:09:47,580 --> 00:09:51,500 off of certain individuals founded it in 1492. 189 00:09:51,780 --> 00:09:54,780 Then discovery occurred 12 years before the shark was born. 190 00:09:54,780 --> 00:09:59,020 If its birth date is 15 O four is more accurate than 1744. 191 00:09:59,020 --> 00:10:02,740 So the way that carbon dating the plus or minus gives that 120 192 00:10:02,740 --> 00:10:05,020 years on either, and I believe so. 193 00:10:05,300 --> 00:10:10,540 Once again, not very technical on this, but these sharks also 194 00:10:10,540 --> 00:10:14,580 have a very interesting parasite which is a wild sentence to 195 00:10:14,580 --> 00:10:18,920 write. The copepod Omato Koteia 196 00:10:19,200 --> 00:10:24,040 elongate, someone correct me, is found on the eye of Greenland 197 00:10:24,040 --> 00:10:26,840 sharks and will eat away causing the shark to become blind. 198 00:10:27,240 --> 00:10:30,320 These sharks do mostly rely on smell and sound to hunt, so 199 00:10:30,320 --> 00:10:32,120 losing their eyesight does not hinder them. 200 00:10:32,120 --> 00:10:34,440 As the majority of the species have these parasites. 201 00:10:34,800 --> 00:10:38,520 They are also found in very low light areas, so not having 202 00:10:38,520 --> 00:10:41,240 eyesight probably was part of the package from the go. 203 00:10:42,120 --> 00:10:44,800 It is believed that these parasites may be bioluminescent, 204 00:10:44,880 --> 00:10:48,000 which means that they glow at night and they might help lure 205 00:10:48,000 --> 00:10:49,800 prey in for the shark so they can eat. 206 00:10:50,080 --> 00:10:52,080 Although that has not been proven, there's a lot of 207 00:10:52,080 --> 00:10:55,400 theories about these sharks. Researchers also believe that 208 00:10:55,400 --> 00:10:59,000 these sharks reach reproductive maturity when they are 150 years 209 00:10:59,000 --> 00:11:02,200 old, and efforts to protect these sharks is needed since it 210 00:11:02,200 --> 00:11:05,520 takes them so long to mature, thus putting the population at 211 00:11:05,520 --> 00:11:07,760 risk. These sharks have some 212 00:11:07,760 --> 00:11:11,270 adaptations to help them survive, such as two nitrogenous 213 00:11:11,270 --> 00:11:14,510 compounds that help increase buoyancy as well as adapt to the 214 00:11:14,510 --> 00:11:18,430 breakdown caused by deep water pressure and urea. 215 00:11:19,430 --> 00:11:22,350 They also possess three types of hemoglobin in their blood to 216 00:11:22,350 --> 00:11:25,830 help slow the use of oxygen, helping with the longevity, 217 00:11:25,830 --> 00:11:28,790 especially living in lower oxygen depths and temperatures. 218 00:11:29,270 --> 00:11:35,290 The screen the skin of Greenland sharks is toxic to consume and 219 00:11:35,290 --> 00:11:37,490 has caused sled dogs who consumed it to have trouble 220 00:11:37,490 --> 00:11:39,330 standing and performing other duties. 221 00:11:40,130 --> 00:11:42,970 There are ways to treat it and it will detoxify it, but it can 222 00:11:42,970 --> 00:11:46,330 involve boiling, burying it and leaving it for weeks to months 223 00:11:46,330 --> 00:11:48,690 to be detoxified, and that's if you're trying to consume the 224 00:11:48,690 --> 00:11:51,210 skin. Greenland sharks also have a 225 00:11:51,210 --> 00:11:55,450 strong position in Inuit legend due to their high urea content 226 00:11:55,450 --> 00:11:59,410 in their skin and their size. One such legend is that the an 227 00:11:59,410 --> 00:12:02,130 old woman washed her hair in urine, which at the time was a 228 00:12:02,130 --> 00:12:05,450 very common cure to head lice. Thank God we have other methods 229 00:12:05,450 --> 00:12:08,770 now, but the rag she used to dry her hair blew into the ocean, 230 00:12:08,770 --> 00:12:10,450 becoming the first Greenland shark. 231 00:12:11,170 --> 00:12:14,690 Another story is of Sedna, an Inuit legend, where her father 232 00:12:14,690 --> 00:12:16,330 cut off her fingers and drowned her. 233 00:12:16,330 --> 00:12:20,050 Not quite sure why, but each of her fingers became a different 234 00:12:20,050 --> 00:12:22,370 creature of the sea. One such being the Greenland 235 00:12:22,370 --> 00:12:25,740 shark, and I do believe another one was one of the seals, but it 236 00:12:25,740 --> 00:12:28,060 it goes on through there but it's very violent and messed up. 237 00:12:28,060 --> 00:12:31,340 But we were not there. They have cemented themselves as 238 00:12:31,340 --> 00:12:33,460 the apex predator of the Arctic Ocean. 239 00:12:34,260 --> 00:12:37,220 Although they are currently listed as vulnerable because of 240 00:12:37,220 --> 00:12:40,580 bycatch, being hunted for their oils and the amount of time it 241 00:12:40,580 --> 00:12:44,180 takes them to become mature and able to repopulate Their numbers 242 00:12:44,180 --> 00:12:48,160 can go down much quicker than they can go back up, but that is 243 00:12:48,160 --> 00:12:51,840 what I have for the shark portion of the podcast. 244 00:12:51,840 --> 00:12:54,640 Of course send any questions, anything like that, any 245 00:12:54,640 --> 00:12:58,080 suggestions over to the social media and I can answer it there 246 00:12:58,080 --> 00:12:59,960 or put it in a future episode as well. 247 00:13:00,680 --> 00:13:04,480 Now moving on to shark safety, for this week we simply went 248 00:13:04,480 --> 00:13:07,240 over how to help sharks in your everyday life, so it's a little 249 00:13:07,240 --> 00:13:08,840 bit different than what we normally do. 250 00:13:09,240 --> 00:13:12,080 This was brought to us by World of Sharks, by the Save Our Seas 251 00:13:12,080 --> 00:13:16,080 foundations and also another great podcast to look up is 252 00:13:16,480 --> 00:13:18,400 World of Shark There, it's a great one too. 253 00:13:19,160 --> 00:13:22,440 But I typically go over what to do if you're on the beach and 254 00:13:22,440 --> 00:13:24,520 this happens, That happens. How to protect sharks? 255 00:13:24,520 --> 00:13:27,720 How to protect yourselves? But I really always hear about 256 00:13:27,720 --> 00:13:31,160 how we can do stuff in our everyday life to protect sharks 257 00:13:31,160 --> 00:13:33,320 and then never really knew what to do. 258 00:13:33,680 --> 00:13:36,080 And then by the time it'd be ready for me to actually look 259 00:13:36,080 --> 00:13:38,400 into it, my ADHD would kick in and I'd forget. 260 00:13:38,840 --> 00:13:42,960 So I decided instead of just telling you guys all that just 261 00:13:43,000 --> 00:13:45,160 do stuff and change stuff, that I'll actually do the research 262 00:13:45,160 --> 00:13:47,640 and give you the suggestions to help support sharks no matter 263 00:13:47,640 --> 00:13:50,640 where you live. So the 1st way that you can help 264 00:13:50,640 --> 00:13:54,560 sharks revolves around by catch and by catch is when fisheries 265 00:13:54,560 --> 00:13:58,040 are going for a certain fish but end up with other fish such as 266 00:13:58,040 --> 00:14:00,800 sharks in their Nets which ends up killing the shark. 267 00:14:01,320 --> 00:14:03,280 Of course I'm not going to tell you to manage your by catch 268 00:14:03,280 --> 00:14:05,480 because if you're rod or real fishing, you aren't really going 269 00:14:05,480 --> 00:14:08,160 to get a shark as by catch. And if you live in a landlocked 270 00:14:08,160 --> 00:14:10,640 area and you don't fish at all, but you can still be 271 00:14:10,640 --> 00:14:12,160 contributing to it without realizing. 272 00:14:12,720 --> 00:14:15,760 So fish such as tuna and swordfish create a lot of 273 00:14:15,760 --> 00:14:19,360 bycatch and these can be bought in canned forms in many grocery 274 00:14:19,360 --> 00:14:21,400 stores. A way to help sharks is to look 275 00:14:21,400 --> 00:14:24,720 at the can before you buy and find brands that say sustainably 276 00:14:24,720 --> 00:14:28,120 caught and for the Blue fish label by the Marine Stewardship 277 00:14:28,120 --> 00:14:31,880 Council that certifies the fish was in fact sustainably caught. 278 00:14:32,320 --> 00:14:35,280 This helps to maintain fish populations as well as limit the 279 00:14:35,280 --> 00:14:37,520 amount of sharks lost due to by catch. 280 00:14:38,400 --> 00:14:41,480 There's also shark meat in markets that is disguised as 281 00:14:41,480 --> 00:14:45,440 other types of meat, such as rock, flake or husk. 282 00:14:45,440 --> 00:14:49,160 Meat can be shark. In actuality, these types of 283 00:14:49,160 --> 00:14:52,240 meats could be spiny dogfish or even scalloped hammerhead or 284 00:14:52,240 --> 00:14:55,120 short fin Mako. It does get tricky though, as 285 00:14:55,120 --> 00:14:57,960 living in Maryland and going out on the Chesapeake Bay I've gone 286 00:14:57,960 --> 00:15:01,640 and caught rockfish so it wasn't uncommon to see rockfish meat 287 00:15:01,640 --> 00:15:05,450 there, so of course rockfish aren't actually sharks. 288 00:15:05,770 --> 00:15:08,490 There are some meats that will be classified as that though, so 289 00:15:08,490 --> 00:15:11,970 it's always OK to ask how it was caught and if it looks suspect 290 00:15:11,970 --> 00:15:14,250 just by something else. There's no need to harass or 291 00:15:14,250 --> 00:15:15,890 argue. The vendor is they might just 292 00:15:15,890 --> 00:15:18,130 work there and they weren't part of catching or filleting the 293 00:15:18,130 --> 00:15:21,210 fish, so they really don't know. So you can ask your questions. 294 00:15:21,210 --> 00:15:23,050 If they don't really have a good answer, they don't know 295 00:15:23,050 --> 00:15:25,010 themselves, just pick something different. 296 00:15:25,010 --> 00:15:29,010 Worst case scenario. Now shark bits can also be found 297 00:15:29,010 --> 00:15:32,680 in certain cosmetics, so be sure to check your products that use 298 00:15:32,680 --> 00:15:36,160 squalene or squalene, which is interesting. 299 00:15:36,160 --> 00:15:43,280 So it's SQUALENE or SQUALANEA product from shark liver oil as 300 00:15:43,280 --> 00:15:46,040 one of the ingredients. Sharks aren't only haunted for 301 00:15:46,040 --> 00:15:48,920 their meat, they're also haunted for cosmetics and similar 302 00:15:49,000 --> 00:15:52,280 products. With this as well, you can reach 303 00:15:52,280 --> 00:15:54,240 out to your legislators. Of course, if you live in a 304 00:15:54,240 --> 00:15:57,880 landlocked area, it's rather easy to not overfish the sharks 305 00:15:57,880 --> 00:16:00,720 in your state or country, since you may not have a fishing 306 00:16:00,720 --> 00:16:03,840 industry that target sharks really at all, or any fish for 307 00:16:03,840 --> 00:16:05,680 that matter. But you can still reach out to 308 00:16:05,680 --> 00:16:08,720 politicians in Congress, in the US, or the equivalent in your 309 00:16:08,720 --> 00:16:11,320 country to back sustainable fisheries and create 310 00:16:11,320 --> 00:16:14,640 restrictions around overfishing. This doesn't necessarily mean to 311 00:16:14,640 --> 00:16:17,440 go as heavy as a shark finning ban, which many countries have 312 00:16:17,440 --> 00:16:20,920 done as this was helpful, but there still is need for seafood, 313 00:16:20,920 --> 00:16:23,640 so banning fishing all together isn't really an option. 314 00:16:24,240 --> 00:16:27,050 I'll admit, I do love seafood, but I want to be able to 315 00:16:27,050 --> 00:16:29,090 continue to eat seafood throughout the rest of my life 316 00:16:29,090 --> 00:16:31,330 and not think back on the times that I could eat a fish. 317 00:16:31,650 --> 00:16:34,810 So we need governmental help to put some regulations out there 318 00:16:35,010 --> 00:16:37,730 to protect our oceans, to allow the population to flourish and 319 00:16:37,730 --> 00:16:41,410 be around for years to come. Now this one is a huge one. 320 00:16:41,730 --> 00:16:44,210 This one is to limit your carbon footprint. 321 00:16:44,690 --> 00:16:47,490 This pretty much says to try to limit the amount of impact you 322 00:16:47,490 --> 00:16:50,370 have on the environment. Bike or walk instead of taking a 323 00:16:50,370 --> 00:16:51,450 car. Recycle. 324 00:16:51,450 --> 00:16:54,170 When possible, try to use less water and electricity. 325 00:16:54,530 --> 00:16:57,050 Live by the motto Reduce, reuse, recycle. 326 00:16:57,450 --> 00:16:59,730 Of course it's easier for some people than others. 327 00:17:00,690 --> 00:17:04,329 Currently it takes me to get to work about 20 minutes by car and 328 00:17:04,329 --> 00:17:06,369 by bus. It would take me an hour 15 329 00:17:06,530 --> 00:17:09,329 because there isn't a route from my apartment to where I work and 330 00:17:09,329 --> 00:17:12,089 I don't have a train option and walking would take about 5 331 00:17:12,089 --> 00:17:13,849 hours. So there's really a better 332 00:17:13,849 --> 00:17:16,369 option by car for now. I might be switching jobs, but 333 00:17:16,369 --> 00:17:18,450 whatever. But I'm not going to argue to 334 00:17:18,450 --> 00:17:20,530 ban cars because that's not a realistic option. 335 00:17:20,530 --> 00:17:23,569 Of course we need cars, but if there's a way that you can walk 336 00:17:23,569 --> 00:17:26,880 somewhere, or if you can get around biking or doing something 337 00:17:26,880 --> 00:17:29,240 similar, that's a good option too. 338 00:17:29,240 --> 00:17:31,040 Yeah, biking is not an option for my current job either. 339 00:17:31,040 --> 00:17:34,560 It's I got to go on a highway. It's a problem, but it's going 340 00:17:34,560 --> 00:17:36,760 to be a big fight to take up and seems like it doesn't really 341 00:17:36,760 --> 00:17:40,400 matter what one person does, but the more people that are doing 342 00:17:40,400 --> 00:17:43,430 it makes a bigger impact. So of course you might get a 343 00:17:43,430 --> 00:17:45,790 little bit discouraged, but do what you can and don't feel 344 00:17:45,790 --> 00:17:48,350 guilty for what you cannot. We've all accidentally littered 345 00:17:48,350 --> 00:17:50,990 before when we went took a piece of trash we were going to throw 346 00:17:50,990 --> 00:17:54,310 away and put it into the water or throw it out the car window 347 00:17:54,310 --> 00:17:56,990 or something like that. We've all made that mistake and 348 00:17:56,990 --> 00:17:59,950 we've all accidentally littered, so just don't throw trash out of 349 00:17:59,950 --> 00:18:01,910 your car. Recycle when possible, check 350 00:18:01,910 --> 00:18:05,030 labels for sustainable practices and try not to use products that 351 00:18:05,030 --> 00:18:07,550 have shark bits in them. So that's really all you got to 352 00:18:07,550 --> 00:18:09,640 do. Of course, if you're even trying 353 00:18:09,640 --> 00:18:12,240 in the 1st place, that's a huge step because of course we're 354 00:18:12,240 --> 00:18:15,680 fighting this uphill battle. But every little bit counts and 355 00:18:15,680 --> 00:18:18,840 that is what I have for the shark safety bit for this week. 356 00:18:19,080 --> 00:18:22,400 Little bit quicker, but there's not a whole lot that we can do 357 00:18:22,800 --> 00:18:25,160 in our everyday life other than just those things mentioned 358 00:18:25,160 --> 00:18:28,120 because those are the biggest ways that sharks are caught and 359 00:18:28,120 --> 00:18:30,480 haunted for. So of course, if we limit those, 360 00:18:30,880 --> 00:18:33,760 that will also limit the amount of sharks that go missing in the 361 00:18:33,760 --> 00:18:36,400 amount of populations that we have to list as extinct. 362 00:18:37,170 --> 00:18:40,490 But moving into shark news, I do have two nice stories for you 363 00:18:40,490 --> 00:18:43,450 guys this week. Well, I'd say they're both 364 00:18:43,450 --> 00:18:46,610 interesting at least, but one's one's a little bit of a roller 365 00:18:46,610 --> 00:18:47,650 coaster, but we'll get into that. 366 00:18:48,410 --> 00:18:51,810 The first one that I have is that 6 bull sharks inadvertently 367 00:18:51,810 --> 00:18:55,970 made made their home on an Australian golf course and then 368 00:18:55,970 --> 00:18:58,250 they vanished. And this was reported by CNN. 369 00:18:58,250 --> 00:19:00,490 So this is the one that's a roller coaster, so strap in. 370 00:19:01,010 --> 00:19:02,450 But this is definitely worth a read. 371 00:19:02,450 --> 00:19:05,850 And look, the golf course is landlocked but has some lakes 372 00:19:05,850 --> 00:19:09,820 across the course and after some heavy rains and flooding in 1990 373 00:19:09,820 --> 00:19:15,700 one 9596 and 2013, there was AI always want to say, land bridge. 374 00:19:15,700 --> 00:19:18,020 But that's the opposite thing. If your guys are history buffs, 375 00:19:18,020 --> 00:19:20,500 you know that the land bridge was that bit from Russia to 376 00:19:20,980 --> 00:19:23,260 Alaska. Anyway, I could go on about that 377 00:19:23,260 --> 00:19:24,740 forever. But anyway, it was more of like 378 00:19:24,740 --> 00:19:27,980 a river. It created a a water bridge from 379 00:19:27,980 --> 00:19:33,540 the lake to the river nearby. Over that time 6 juvenile bull 380 00:19:33,540 --> 00:19:37,070 sharks had swam into the lake and did not leave before the way 381 00:19:37,070 --> 00:19:40,230 back to the river dried up. Now there had been rumors that 382 00:19:40,230 --> 00:19:42,750 sharks have been spotted, but nobody really believed them 383 00:19:42,750 --> 00:19:45,310 until someone got a video that they called terrible. 384 00:19:45,310 --> 00:19:47,870 But it was actually a great image of the shark I could 385 00:19:47,870 --> 00:19:50,110 identify that was a bull shark right from that video. 386 00:19:50,110 --> 00:19:54,590 It was taken a way long time back, but that quality it holds 387 00:19:54,590 --> 00:19:56,960 up. So from there, the Golf Club 388 00:19:56,960 --> 00:20:00,160 then embraced its new shark mascots and added a shark to 389 00:20:00,160 --> 00:20:03,200 their logo, as well as renaming their youth program as the 390 00:20:03,200 --> 00:20:06,000 Junior Shark Academy, which I absolutely love. 391 00:20:06,000 --> 00:20:07,280 This is the way that you should do it. 392 00:20:07,640 --> 00:20:11,040 They also did put up signs, let people know, and they forbid 393 00:20:11,040 --> 00:20:14,200 swimming, as well as not letting anyone go into the lake to die 394 00:20:14,200 --> 00:20:17,200 for golf balls because there's bull sharks there. 395 00:20:17,200 --> 00:20:20,600 They it's kind of the same thing I've said in previous safety 396 00:20:20,600 --> 00:20:23,610 segments where. The easiest way to not get bit 397 00:20:23,610 --> 00:20:25,250 by a shark is don't go in the water. 398 00:20:25,250 --> 00:20:30,130 And if you know there's six bull sharks in a lake, maybe don't 399 00:20:30,290 --> 00:20:32,650 jump into the lake. It's just an idea. 400 00:20:33,450 --> 00:20:36,450 But unfortunately since then these sharks have gone missing. 401 00:20:37,250 --> 00:20:39,770 Only two were found dead. One was floating at the surface 402 00:20:39,770 --> 00:20:43,280 after a large storm which they assumed that one killed it and 403 00:20:43,280 --> 00:20:45,920 then one was just illegally fished, which is rather 404 00:20:45,920 --> 00:20:47,920 upsetting. But they believe that after a 405 00:20:47,920 --> 00:20:51,240 large storm in 2013 that created more flooding, the sharks 406 00:20:51,240 --> 00:20:54,080 returned to the river or they were killed by the storm. 407 00:20:54,080 --> 00:20:57,720 Unfortunately now they do not believe that these sharks could 408 00:20:57,720 --> 00:21:01,680 have died in natural ways if they were killed, but more 409 00:21:01,680 --> 00:21:05,160 recent flooding officials hope that this brings more sharks 410 00:21:05,160 --> 00:21:07,480 into the lake. They they do have plans to 411 00:21:07,480 --> 00:21:10,280 eventually fill in that lake, although they will move all 412 00:21:10,280 --> 00:21:13,470 residents, any fish or sharks to redo the course. 413 00:21:13,470 --> 00:21:15,190 And they'll remove them, relocate them. 414 00:21:15,190 --> 00:21:17,550 So that way they're not just going to kill a shark, which is 415 00:21:17,910 --> 00:21:20,870 I think, awesome, but they're hoping that more sharks end up 416 00:21:20,870 --> 00:21:22,710 in the lakes. That way they can have that nice 417 00:21:22,790 --> 00:21:24,710 image once again. But yeah, I thought that was 418 00:21:24,710 --> 00:21:27,670 kind of neat, especially because it was a freshwater lake and it 419 00:21:27,790 --> 00:21:31,110 goes to show how adaptable bull sharks are they they're kind of 420 00:21:31,110 --> 00:21:35,370 tanks of the ocean. It's rather nuts, but we do have 421 00:21:35,370 --> 00:21:38,290 another story. That is a new species of shark 422 00:21:38,290 --> 00:21:42,450 discovered in Mammoth Cave, and this is from Fox 56 in Kentucky. 423 00:21:42,930 --> 00:21:47,010 So new shark just dropped kind of Researchers digging in the 424 00:21:47,010 --> 00:21:50,610 Saint Genevieve Formation layer of rock were able to find the 425 00:21:50,650 --> 00:21:54,610 Petal tooth shark fossil. Mammoth Cave National Park has 426 00:21:54,610 --> 00:21:58,170 been turning up many fossil records recently as researchers 427 00:21:58,170 --> 00:22:01,490 and paleontologists have had more access to the park and its 428 00:22:01,490 --> 00:22:04,570 resources. They named the specific species 429 00:22:04,570 --> 00:22:07,810 after a guide at the park who has helped to find many fossils 430 00:22:07,810 --> 00:22:11,610 since the program began in 2019. Now, this is an amazing 431 00:22:11,610 --> 00:22:15,810 archaeological, archaeological discovery and hopefully will be 432 00:22:15,810 --> 00:22:19,210 the first of many more to come. Of course, some of you may be 433 00:22:19,210 --> 00:22:22,850 wondering how fish fossils ended up in landlocked areas, and 434 00:22:22,850 --> 00:22:25,290 that's simply because of how the Earth has shifted over the 435 00:22:25,290 --> 00:22:26,850 billions of years it's been around. 436 00:22:27,260 --> 00:22:29,260 I mentioned in the Megalodon episode that they're known 437 00:22:29,260 --> 00:22:32,100 breeding grounds were on the Eastern Shore of Maryland and 438 00:22:32,100 --> 00:22:35,900 Central Florida, both of which are near the Atlantic Ocean, but 439 00:22:35,900 --> 00:22:38,940 both are about an hour drive or more from the water. 440 00:22:39,180 --> 00:22:41,540 Florida also has the Gulf of Mexico, and Maryland has the 441 00:22:41,540 --> 00:22:44,500 Chesapeake Bay, but both are still about an hour anywhere 442 00:22:44,500 --> 00:22:46,220 from where the Megalodon used to breed. 443 00:22:46,220 --> 00:22:49,980 So as the Earth shifted, waterways became land, land 444 00:22:49,980 --> 00:22:53,500 became water, and different fossils get in different places. 445 00:22:54,160 --> 00:22:57,760 But that is what I had for the new segment of this episode and 446 00:22:57,840 --> 00:22:59,320 that's pretty much it for this episode. 447 00:22:59,320 --> 00:23:02,320 So thank you all for listening. Of course, follow along on the 448 00:23:02,320 --> 00:23:04,400 social media. If you have any questions, any 449 00:23:04,400 --> 00:23:06,800 comments, any concerns, send them in to me. 450 00:23:07,120 --> 00:23:10,000 And of course, I will see you guys in the next one. 451 00:23:10,400 --> 00:23:10,920 Take care.
