[SPEAKER_00]: Welcome to Freaky Fana Friday, where every Friday we take a little time and explore some of the freaks of nature from around the planet.
[SPEAKER_00]: We cherish so deeply.
[SPEAKER_00]: So please jump aboard and let's explore the wilds together.
[SPEAKER_02]: Welcome back to Freaky Fana Friday.
[SPEAKER_02]: I am the great end.
[SPEAKER_02]: Peace
[SPEAKER_02]: And today we're going to talk about one of my favorite animals who fish it is a fish I knew it But that's always kind of the joke, isn't that why favorite animals.
[SPEAKER_02]: Yeah, well, no, that it's all these animals.
[SPEAKER_02]: I love all of them.
[SPEAKER_02]: Oh, they're all one of your favorites.
[SPEAKER_02]: It's very few animals.
[SPEAKER_02]: I don't hate any animal.
[SPEAKER_02]: But there's very few animals that I didn't like I don't like and the ones I really don't like are domestic.
[SPEAKER_02]: Let's just say house cats.
[SPEAKER_02]: And it's not even like, if you keep your house cat in the house, they're fine, right?
[SPEAKER_02]: They're just very environmentally destructive.
[SPEAKER_01]: Trying to do what else you don't like, though.
[SPEAKER_02]: Common carp rabbits, domestic rabbits, and it's the fur.
[SPEAKER_02]: It's nothing to do with rabbits.
[SPEAKER_02]: I just don't like the fur.
[SPEAKER_02]: Oh, I like the fur.
[SPEAKER_01]: Whatever my tism is, oh, I think it's nice and soft and warm.
[SPEAKER_02]: But Taylor and talk about Tiger Sharks.
[SPEAKER_02]: Oh, okay.
[SPEAKER_02]: I've got to see these guys in a while, a couple times, little ones.
[SPEAKER_02]: I relatively speak, and you know, six foot long.
[SPEAKER_02]: Okay.
[SPEAKER_02]: But that size are very thin.
[SPEAKER_02]: Like, if they don't get really stocky into their like above 10 feet.
[SPEAKER_02]: But yeah, Tiger Sharks, Tiger Sharks are your species of the family.
[SPEAKER_02]: Car, car, affiliate, which is, you know, some of your most famous sharks belong to that.
[SPEAKER_02]: So well known for its extremely large size
[SPEAKER_01]: Yeah, that's all I know about them.
[SPEAKER_01]: Let's talk about that.
[SPEAKER_02]: Yeah, aggressive.
[SPEAKER_02]: It's, I don't like using that word for sharks because tiger sharks are extremely curious animals.
[SPEAKER_02]: And like great whites.
[SPEAKER_02]: They have their sensory organs or in their mouth.
[SPEAKER_02]: Okay, so they actually have an organ inside their gum line that tells them chemical composition of things.
[SPEAKER_01]: Oh, wow.
[SPEAKER_01]: So they're chewers.
[SPEAKER_02]: They have to.
[SPEAKER_02]: They don't have hands.
[SPEAKER_02]: Right.
[SPEAKER_02]: And they're very curious animals.
[SPEAKER_02]: Uh, so you'll see tiger sharks that we'll we'll talk about some of their things they do.
[SPEAKER_02]: But they'll bite and it's not because they're aggressive at per se.
[SPEAKER_02]: It's because they're curious.
[SPEAKER_02]: But we are soft compared to them.
[SPEAKER_02]: Right.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: We don't want to get it by a tiger shark.
[SPEAKER_02]: Don't go in the ocean.
[SPEAKER_01]: it's like it's like you've got a gusher and you want to know what that flavor inside is like I wouldn't wait a really truly find out you got to poke a hole in it with your bite and
[SPEAKER_01]: have will taste.
[SPEAKER_02]: Uh, the name tiger shark comes from their tiger like dark stripes on their skin, which are clearly visible along the bodies, especially in young tiger sharks.
[SPEAKER_02]: They do when you start seeing some of the really big old females, specifically, they do start fading, but they're still there.
[SPEAKER_02]: They're just not as vibrant.
[SPEAKER_02]: What's that?
[SPEAKER_02]: The stripes?
[SPEAKER_02]: Oh, the stripes?
[SPEAKER_02]: Okay, okay, okay.
[SPEAKER_02]: As they get older, they do kind of fade.
[SPEAKER_02]: And these guys live a long time, but we'll get to that.
[SPEAKER_02]: Tropical and sub-tropical and warmer tempered salt waters is where these guys inhabit They do inhabit deep oceans as well as shallow coastal regions So these are a really cool animals because you can run into these in five six seven hundred feet of water out in the open ocean Okay, and or they can be in four foot of water.
[SPEAKER_01]: Yeah, I'm a close.
[SPEAKER_02]: Yeah, uh, they're probably as all of the large sharks the most opportunistic
[SPEAKER_02]: and the most diverse and adaptable.
[SPEAKER_02]: Long as it's not temperature driven.
[SPEAKER_02]: So I got a big range of habitats.
[SPEAKER_02]: When you're comparing them to like a bull shark, bull sharks have a much bigger range in temperatures.
[SPEAKER_02]: Oh, okay, but tire sharks really don't like cold water.
[SPEAKER_02]: Okay.
[SPEAKER_02]: So they will avoid that.
[SPEAKER_02]: But besides that, I mean, you'll see them pop up in the open ocean.
[SPEAKER_02]: But yeah, worldwide seas and oceans excluding the Mediterranean sea.
[SPEAKER_02]: But yeah, so anywhere that's pretty much along the equator, every ocean, they're they're going to be there.
[SPEAKER_02]: Okay.
[SPEAKER_02]: They live up to 50 years.
[SPEAKER_02]: In some cases, 70 years old.
[SPEAKER_02]: That's an old fish.
[SPEAKER_02]: uh... right now conservative estimates of the largest living individuals around sixteen feet with historic estimates putting them at eighteen to twenty feet so just a little smaller and then uh... that's kind of comparable to light bullsharks uh... but you know lots more than like a great white
[SPEAKER_02]: Yeah, and up to 2,000 pounds, okay, that's pretty big, making the second heaviest of the, like, predatory sharks you're going to run into is real in in a car.
[SPEAKER_02]: Yeah, I mean, if you ever seen people catch them, it is like that.
[SPEAKER_02]: No, I don't think I've seen that.
[SPEAKER_02]: The people catch them in like Daytona and stuff like that.
[SPEAKER_02]: They're not super common.
[SPEAKER_02]: So like if you're in Florida, for example, and you run into a large shark, it's gonna be a bull shark.
[SPEAKER_02]: Okay, just because there's just the number of them.
[SPEAKER_02]: They're just much more abundant, coast lay in Florida, right?
[SPEAKER_02]: The odds are that's what's gonna be.
[SPEAKER_02]: There are tigers there.
[SPEAKER_02]: Tigers do pop in Florida, but yeah, if you run into a big shark, it's gonna be a bull shark.
[SPEAKER_02]: which you know a big big bullshark is like eight and nine hundred pounds and a big tiger is 2,000, 2500 pounds.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: But yeah, there's skin color ranges from everything from a dark blue to a light green and they even have overall gray huge to their body.
[SPEAKER_02]: But they all have these these dark vertical bars in some times spots and their flanks with pale or white undersides.
[SPEAKER_02]: other diet.
[SPEAKER_02]: Everything.
[SPEAKER_02]: Yeah, these guys pretty much eat anything.
[SPEAKER_02]: Hmm, crustaceans fish seals birds, squids, turtles, sea snakes, dolphins, smaller sharks, each other if it bleeds.
[SPEAKER_01]: We can kill it.
[SPEAKER_02]: Oh, it's not even that.
[SPEAKER_02]: Tires, license plates, suits of armors, buckets of nails, magnets.
[SPEAKER_01]: How tough are you?
[SPEAKER_01]: How tough am I?
[SPEAKER_01]: I had a bowl of nails for a breakfast.
[SPEAKER_02]: The tiger shark actually did without any milk They really only have a couple predators larger sharks.
[SPEAKER_02]: You know, so there would be great whites Bulls sharks dependent on their size and other tigers killer whales pilot whales and humans Cash to pilot whales
[SPEAKER_01]: or even pilot wheels?
[SPEAKER_02]: No, no, no, pilot wheels are eating them.
[SPEAKER_01]: Oh, oh, that's their predators, I was gonna say.
[SPEAKER_02]: Whew.
[SPEAKER_02]: They actually, despite their appearance, they can be quite fast up to 35 miles per hour.
[SPEAKER_01]: Let's just say I thought they could move like in short bursts, right?
[SPEAKER_02]: Yeah.
[SPEAKER_02]: But they just look like their big slow things.
[SPEAKER_02]: They move like that a lot.
[SPEAKER_02]: There's only one species for an oceanic worldwide animal, pretty impressive.
[SPEAKER_02]: They are near threatened as controversial status.
[SPEAKER_02]: Hmm.
[SPEAKER_02]: Okay.
[SPEAKER_02]: But yeah.
[SPEAKER_02]: So this species is geocordo-carver, which is not the sand tiger shark.
[SPEAKER_02]: They are not closely related whatsoever.
[SPEAKER_02]: There's the tiger shark, and then there's the sand tiger shark.
[SPEAKER_02]: Oh, I didn't know there was.
[SPEAKER_01]: Santa's sharks.
[SPEAKER_02]: No, no, they're not related.
[SPEAKER_02]: Yeah, it's just a name.
[SPEAKER_02]: OK.
[SPEAKER_02]: They're just both kind of stripes.
[SPEAKER_02]: OK. Tiger sharks directly, though.
[SPEAKER_02]: The tiger shark is one of the repquim sharks renowned for its formidable predatory powerful jell's and razor sharp teeth.
[SPEAKER_02]: Is the second largest predatory shark after the great white shark?
[SPEAKER_02]: Uh, and this can change a little bit because some of the oceananic deep sea sharks may be bigger, but it's just unpredictable like six gills and green ones and stuff like that.
[SPEAKER_01]: Well, that's too hard to.
[SPEAKER_01]: I are not abundant enough to study them.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: Uh, their fan worldwide marine environments in a warm water, particularly in the central Pacific islands is where some of the biggest ones in the world are anywhere from 45 degrees north.
[SPEAKER_02]: The 32 degrees south with occasional sightings and cooler temperate zones may be due to seasonal warm current changes, such as the Gulf stream.
[SPEAKER_02]: uh... so yeah they really don't pop out of the state within those uh... was it longitude uh... latitudes latitudes long a latitudes yeah they stay within those latitudes pretty much but occasional warmspikes can have them moving out okay they are near threatened due to the excessive fitting operations done by humans like shark finns
[SPEAKER_02]: Tiger sharks are heavily tackled for that.
[SPEAKER_02]: That's wild.
[SPEAKER_02]: They do not breed a lot.
[SPEAKER_02]: So they are extremely important for the ecosystems they manage.
[SPEAKER_02]: People really don't get this.
[SPEAKER_02]: It's a highly controversial topic because humans are scared of predators because it's nature, right?
[SPEAKER_02]: Right.
[SPEAKER_02]: We're scared of things that can eat us.
[SPEAKER_02]: But for healthy environments, apex predators need to be present, right?
[SPEAKER_02]: And people, a lot of people don't get that, a lot of people do get that.
[SPEAKER_02]: Uh, so it's, it's, it's really hard to put that on.
[SPEAKER_02]: Like, there's people like, I don't want Tiger sharks off my beach.
[SPEAKER_02]: Well, that's how your beach stays healthy, right?
[SPEAKER_02]: If you're scared, like, or my thing, if set it forever, if you're scared of sharks, don't go in the water.
[SPEAKER_02]: Don't go in the ocean.
[SPEAKER_02]: They live there.
[SPEAKER_02]: It's where they live, yep.
[SPEAKER_02]: like I hate hate hate shark and fester waters and the news always says that they're not infested they live in the ocean right it's human in fester waters yeah we don't need to be uh you don't need to be swimming in there at that time of day oh yeah just we have pools like right really scared of sharks there's a pool there's sharks in there
[SPEAKER_02]: Tiger sharks are mostly nocturnal apex predators.
[SPEAKER_02]: Their diet is extremely varied, including fish, sea birds, seals, and even more.
[SPEAKER_02]: They have a quite the reputation of being garbage eaters, sometimes consuming inedible manmade objects that can get stuck in their stomachs.
[SPEAKER_02]: The Tiger Shark conservation status is near threatened, like I already said due to that.
[SPEAKER_02]: They also are finned or they're hunted for their rivers, which are high in vitamin oils,
[SPEAKER_02]: You can actually kill yourself from eating a tiger shark liver from vitamin A poisoning.
[SPEAKER_01]: Wow, too much.
[SPEAKER_01]: Yeah A lot of shark livers are like that, but you can like you can't like eat them That's wild that they only that you know some cultures only catch them and get them for their fins It is and there's nothing good for it.
[SPEAKER_02]: Yeah, it is a horrid experience because much time they throw back a live So there's a bunch of them laying on the bottom like suffocating slowly
[SPEAKER_01]: And they just boil the fins for the cartilage, like they don't even, there's no meat in there.
[SPEAKER_02]: I know I've eaten shark.
[SPEAKER_02]: I'm not saying don't eat sharks, but don't waste 99% of the animal.
[SPEAKER_01]: Yeah, or something that's terrible practice.
[SPEAKER_02]: Like I've harvested bull sharks in Florida and black-tivory sharks.
[SPEAKER_02]: And you get so much meat off a one animal.
[SPEAKER_02]: Like one animal is a lot for a family.
[SPEAKER_01]: And I've never had shark like stakes.
[SPEAKER_01]: Just, they're good.
[SPEAKER_01]: That's what I've heard.
[SPEAKER_02]: It's very similar to Liam to me.
[SPEAKER_02]: That's a odd, but neat.
[SPEAKER_02]: Uh, this is one of the sharks species that has the man-eater moniker.
[SPEAKER_02]: This is due to the incidence of fatal attacks on humans.
[SPEAKER_02]: The nickname is misleading, however, as fatal attacks by tiger sharks are extremely rare.
[SPEAKER_02]: With most human fatalities occurring from drowning in coastal waters after the bite.
[SPEAKER_02]: That's sad.
[SPEAKER_02]: Yeah, but yeah, so they're not we talked about that earlier where it's that curiosity bite.
[SPEAKER_02]: Yeah, they're not turning it most like most of the fatalities that are attributed tiger sharks are a bite and then a person drowning after the tiger shark is left.
[SPEAKER_01]: Hmm, I just want to see the, they got your flavor inside.
[SPEAKER_02]: Well, yeah, it's like I said, they're all of their sensory organs in their mouth or in their mouth between their teeth.
[SPEAKER_02]: Tiger shark is ranked second on the list of the number of recorded bites on humans.
[SPEAKER_02]: With 36 recorded fatalities in total, is bull shark number one.
[SPEAKER_02]: I believe I probably is.
[SPEAKER_02]: I don't have that right here in front of me.
[SPEAKER_02]: Oh, okay.
[SPEAKER_02]: I can see that and that's we'll talk about that too.
[SPEAKER_02]: Typically, there are around three to four shark bites per year in Hawaii, which are rarely fatal because they're really soft bites.
[SPEAKER_02]: Just to feel like when a dog's feeling I mean, I know it's hard because there's huge animals Yeah, but it's a case kind of what it is.
[SPEAKER_02]: It's like because they have their sensory organs So most of the bites like from Tiger sharks in Hawaii Are just that is gravity.
[SPEAKER_02]: I just to feel just to see what it is.
[SPEAKER_01]: Yeah, their eyes They don't have a really good vision.
[SPEAKER_01]: It's just a problem is they're grabbing you with that mouthful razor blades But yeah, so
[SPEAKER_02]: with tiger sharks and bull sharks.
[SPEAKER_02]: Why they have so many bites is because of their size, their curiosity and they're coming in contact with humans.
[SPEAKER_02]: Okay, they tip, you know, they're going shallow waters, even for their size.
[SPEAKER_01]: Right, yeah, where people are swimming.
[SPEAKER_01]: We are where they like to be.
[SPEAKER_02]: And if you look at most fatal attacks,
[SPEAKER_02]: are almost always around like ripped hides storm events and what happens is the water gets a little muddy and people still go out.
[SPEAKER_02]: So the tiger shark is getting less of a picture.
[SPEAKER_02]: Even even more so than normal.
[SPEAKER_01]: So it just needs to feel.
[SPEAKER_02]: Yeah, if you're if you're like sharks are very intelligent.
[SPEAKER_02]: I highly advise if you're scared of sharks going up here, a fishing pier and look down at people swimming.
[SPEAKER_02]: So the people have no idea what's around them ever.
[SPEAKER_02]: And you'll see dozens if not hundreds of sharks swimming in and out of people all day every day not biting
[SPEAKER_01]: or sharks like the dogs of the sea.
[SPEAKER_02]: some of them are called dog fish.
[SPEAKER_01]: Actually someone just talked about that last night at the bowling alley to have Mount they were doing charter fishing in Florida and they called a dog fish.
[SPEAKER_02]: They're just little sharks with spines and they've let it.
[SPEAKER_01]: I don't know they didn't know what it was at first and they let it sit in the boat with them.
[SPEAKER_01]: I mean obviously they ate them.
[SPEAKER_02]: Yeah, no they're good eat dog fish actually.
[SPEAKER_02]: There's a commercial fishery for them right now.
[SPEAKER_02]: It's a lot like in the UK it's kind of cool to go to a problem dog fish or the commercial fishing.
[SPEAKER_02]: The dog fish, as in people are selling it as cod.
[SPEAKER_01]: Oh, okay.
[SPEAKER_02]: because it is a it's like a white flaky meat cooks up really nice like proficient ships for fried fish.
[SPEAKER_02]: I've eaten dog vish travel times at restaurants.
[SPEAKER_02]: It's fine.
[SPEAKER_02]: It's good.
[SPEAKER_02]: And there are short-lived fast reproductive shark.
[SPEAKER_02]: So like even like a big one's like three foot long.
[SPEAKER_01]: Okay.
[SPEAKER_02]: They don't get big.
[SPEAKER_01]: It's better to burn out than a fade away.
[SPEAKER_02]: But that's kind of the issue is that there are people are being lied to about what they're eating consuming.
[SPEAKER_02]: They inhabit different kinds of marine environments.
[SPEAKER_02]: This is a newer idea, with nude modern tracking information.
[SPEAKER_02]: We previously thought they pretty much only lived in shallow coastal areas in a rare open ocean and, you know, just traveling in between.
[SPEAKER_02]: We now know that's completely wrong.
[SPEAKER_02]: They feed on anything with nutrient-rich waters they could be found.
[SPEAKER_02]: With their trackers on them, they've been found at 350 meters at depth and traveling and spending considerable amounts of time in the open ocean, following any warm currents between islands just making pit stops.
[SPEAKER_02]: So there's much more of an ocean, an open ocean navigator than we originally thought at all.
[SPEAKER_02]: Yeah, that's why.
[SPEAKER_02]: That's pretty cool.
[SPEAKER_02]: And so the shark that they run into and have the most problems with is probably the greater hammer head because there are another open ocean thing.
[SPEAKER_02]: But we haven't witnessed that a lot.
[SPEAKER_02]: That's kind of more speculation.
[SPEAKER_02]: Yeah, because they're giants, both, you know, marine giants that are habit, that's the most things.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: So they run into each other, which hammerheads can be very, very fierce predators.
[SPEAKER_02]: And they are known to sometimes tackle extremely large prey, like tarpen.
[SPEAKER_02]: Wow.
[SPEAKER_02]: So the dark stripes on the shark, another freaky fun of fact, fade as they mature.
[SPEAKER_02]: Uh, so yeah, so you can kind of get an idea, you know, females are always larger than males, but you can kind of get an idea of age of how faded their stripes are.
[SPEAKER_02]: Gotcha.
[SPEAKER_02]: There's a couple individuals that are very, very old.
[SPEAKER_02]: They almost have no stripes left.
[SPEAKER_02]: And you just tell by their big flathead, clearly faded out.
[SPEAKER_02]: Uh, their skin feels like sandpaper.
[SPEAKER_02]: The surface of their skin is covered with tiny teeth like structures, which are thought to reduce friction in the water as it swims.
[SPEAKER_02]: Some recent research also suggests that the other marine creatures, including fish and a sharks, rub up against tiger sharks to chave off their parasites on their own skin.
[SPEAKER_02]: That's pretty neat.
[SPEAKER_02]: And if you look, a lot of times tiger sharks always have an entourage.
[SPEAKER_01]: like fall and swimming under a man.
[SPEAKER_02]: Yeah, beside him like Kobe, not even just or more as with the sucker fish that stick on him.
[SPEAKER_02]: Yeah, like Kobe, which are cousin or more as that are a sought after game fish, but like a pilot fish, even schools of like sergeant Daniels and stuff like that.
[SPEAKER_02]: They use him for protection, right?
[SPEAKER_02]: Yeah, and just like they'll pick parasites off them.
[SPEAKER_02]: They'll scavenge meals because Tiger sharks are really messy feeders.
[SPEAKER_02]: Mm.
[SPEAKER_02]: So they sit and shake.
[SPEAKER_02]: So they're just shredding meat.
[SPEAKER_02]: So they're getting all the scraps.
[SPEAKER_02]: Yeah, I'm flying off.
[SPEAKER_02]: And some of the benefits would be like that of, you know, picking parasites off their skin and that kind of stuff for the tiger shark.
[SPEAKER_02]: They haven't, they're body has no bones.
[SPEAKER_02]: All cartilage.
[SPEAKER_02]: Yep, their skeleton is made of cartilage, which is the case with all modern day sharks.
[SPEAKER_02]: It is the only species of recum shark with suction holes.
[SPEAKER_02]: So it hangs on stuff.
[SPEAKER_02]: These holes or sparrilia,
[SPEAKER_02]: are situated between their eyes.
[SPEAKER_02]: This helps them oxygenate their blood in vessels that lead directly into their eyes and brain.
[SPEAKER_01]: Huh, okay, so they'll be like pulling in.
[SPEAKER_01]: It's like your nose.
[SPEAKER_01]: Yeah, there's pulling in air, basically water.
[SPEAKER_01]: Well, water, but that.
[SPEAKER_02]: So a lot of sharks have not, like, quote unquote, nostrils for scent.
[SPEAKER_02]: These guys actually use their nostrils.
[SPEAKER_02]: They're the only big predatory shark that use their nostrils to oxygenate blood as well.
[SPEAKER_02]: But it's specifically going to their brain.
[SPEAKER_01]: Brain and eyes.
[SPEAKER_01]: Oh, part of their brain.
[SPEAKER_02]: It has excellent vision in DM light, so the back of their eyeballs has a layer reflective tissue called the tapdom, which enhances night vision.
[SPEAKER_02]: So unlike a lot of sharks, these guys actually have a good vision, and that's why I talked about earlier, that a lot of their bites happen when the water is lost clarity.
[SPEAKER_02]: because they're one of their big things that they used to see and navigate is, you know, they're blind.
[SPEAKER_02]: So they're using their sensory ports, their pressure sensors, their electromagnetic sensors.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: So an arm in a leg is like the size of the fish that they're hunting.
[SPEAKER_01]: What they say that song blinded by the murky water.
[SPEAKER_02]: It can detect the electromagnetic field of prey animals.
[SPEAKER_02]: Like many fish runers relatives, they have small pits on their snout, which are a network of sensory organs called the amplia of Lorenzia.
[SPEAKER_02]: These detect electrical fields, including weak impulses emitted by the prey's heart and brain.
[SPEAKER_01]: So a lot of sharks have this right.
[SPEAKER_01]: Yeah, okay.
[SPEAKER_02]: Some sharks have a much more dramatic one like hammerheads and tigers and yeah, but yeah, it is a social creature.
[SPEAKER_02]: Comey thought to be entirely solitary.
[SPEAKER_02]: Research was a found that it makes choices about other tiger sharks to socialize with, uh, especially when in shallow near coastal waters.
[SPEAKER_02]: It also shows some co-optive hunting strategies forming
[SPEAKER_02]: So we're finding out a lot more of these guys is we're being able to tag them and actually track them.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: Well, they do not like other members and they do enjoy other members.
[SPEAKER_02]: And they will actually kind of hunt together.
[SPEAKER_02]: So this, you don't really see this in large sharks.
[SPEAKER_02]: Sometimes you see it in smaller sharks like black tips.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: Any even the same oceanic animals like mecos and stuff like that.
[SPEAKER_01]: kind of neat knowing the big ones are doing it too.
[SPEAKER_01]: Yeah, it's all rare.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: And it's, we kind of only really see this around like high up on its prey times like macro runs or, you know, start Dean runs, whether just millions of prey.
[SPEAKER_02]: And that can be really hard for actually large animal to take advantage of for one.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: Yeah, for one, because they're just going to keep summing around it, right?
[SPEAKER_02]: So when there's a wall of them, the little fish panic, and then you're more likely to catch.
[SPEAKER_02]: Its diet is the most varied of any shark on the planet.
[SPEAKER_02]: They, many marine animals, pretty much anything they can get their teeth into.
[SPEAKER_02]: Ooh, those stingrays, dolphin seals, squids, turtles, crabs, seabirds, even other sharks.
[SPEAKER_02]: They're like the chowchows of the sea.
[SPEAKER_02]: They anything.
[SPEAKER_02]: They also are known to eat terrestrial animals, such as horses, goats, sheep,
[SPEAKER_02]: There's even a recorded event of a tiger shark consuming some songbirds.
[SPEAKER_02]: Oh, wow, it also is a scavenger of inanible manmade objects that stay undigested and it's stomach.
[SPEAKER_02]: That part said.
[SPEAKER_02]: Oh, don't worry.
[SPEAKER_02]: We'll talk about that.
[SPEAKER_02]: It has a little thing to I could just tell you now.
[SPEAKER_02]: They can't register their stomach if it becomes too full of inan or in digestible objects.
[SPEAKER_02]: Okay.
[SPEAKER_02]: So they actually turn their whole stomach inside out.
[SPEAKER_02]: You can't say their mouth.
[SPEAKER_02]: Kind of it's like an actual stomach though, you see.
[SPEAKER_02]: Yeah, the jaws have a unique shape and definition.
[SPEAKER_02]: Unlike other sharks, it has a square blunt form to its jaw rather than a rounded shape.
[SPEAKER_02]: With its razors teeth are almost identical to on the both upper and lower jaw.
[SPEAKER_02]: Unlike most predatory sharks, which have a cutting layer on the lower jaw and a like a grabbing layer on the upper top.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: Uh, and we think this is because of their very diet.
[SPEAKER_02]: This is a much more efficient way to not efficient.
[SPEAKER_02]: Uh, it's the opposite.
[SPEAKER_02]: It's much more a jack of all trades master of, oh, okay.
[SPEAKER_02]: So it gets everything.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: When you look at like big like white sharks, they have their jolers designed to hunt marine mammals.
[SPEAKER_01]: Catch and shred.
[SPEAKER_02]: Yeah, but they'd have a lot of trouble eating a turtle.
[SPEAKER_01]: Right.
[SPEAKER_01]: Yeah.
[SPEAKER_01]: Even.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: So these guys can eat turtles and marine mammals or they're not extremely great at either of those things.
[SPEAKER_02]: They can get the job.
[SPEAKER_02]: Anything they run into, they can probably.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: They're just can sheer right through flesh, a bone in shell.
[SPEAKER_02]: There's actually videos of these guys slicing through turtle shells.
[SPEAKER_02]: out of the sacred Hawaiian mythology, the tiger shark is considered a sacred animal and traditional Hawaiian culture, thought to be the reincarnation of deceased family members.
[SPEAKER_02]: They can go into a trance like state when it's belly's up.
[SPEAKER_02]: I like immobility.
[SPEAKER_02]: Isn't that a lot of sharks, too?
[SPEAKER_02]: Yeah, I've seen that.
[SPEAKER_02]: That's really neat.
[SPEAKER_02]: The females are larger than the males.
[SPEAKER_02]: You know, so this is known as dimorphism or sexual dimorphism.
[SPEAKER_02]: Uh, yeah, the females are a lot bigger.
[SPEAKER_02]: Like the biggest male is right at the size of an average breeding female.
[SPEAKER_02]: Okay, so females get a lot bigger.
[SPEAKER_02]: Unlike most shark species, the tiger shark hatches fertile eggs inside of its own body and gives birth to life like young.
[SPEAKER_02]: Huh?
[SPEAKER_02]: So it's, it's, it's called oval creativity.
[SPEAKER_02]: So it has eggs.
[SPEAKER_02]: A pregnant female tiger shark lays 10 to 82 eggs inside her own body.
[SPEAKER_02]: Okay.
[SPEAKER_02]: Each egg containing an embryo which feeds on a yolk sack.
[SPEAKER_02]: So a true egg.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: Then the embryos hatch inside the female's body to continue to grow until the mother gives birth to fully develop live young, told gestation period of 13 to 16 months.
[SPEAKER_02]: Wow.
[SPEAKER_02]: So if she starts with 80 eggs, most times she only gives birth to three to five pups.
[SPEAKER_02]: Wow.
[SPEAKER_01]: Because she's eating each other.
[SPEAKER_01]: Oh, okay.
[SPEAKER_01]: So if survival of the fittest at that point.
[SPEAKER_01]: So it's like a little incubation chamber.
[SPEAKER_01]: Yeah.
[SPEAKER_01]: The eggs hatch inside there, and then
[SPEAKER_02]: One male can sire a whole litter of pups.
[SPEAKER_02]: Recent studies indicate that 30 to 35 pups per litter are most commonly sire by one male, not multiple males that was previously thought.
[SPEAKER_02]: because so it would used to be thought that she would be made by several different males.
[SPEAKER_02]: Yeah, and produce a bunch of different offspring.
[SPEAKER_02]: And then it turns out, yeah, one don't get can be just one, yeah, getting the job done.
[SPEAKER_02]: There are at least two different types of tiger shark.
[SPEAKER_02]: Genic research has revealed that there are two distinct populations, one the Atlantic Ocean and the Indo-Pacific Ocean, which have not interbred for a very, very long time.
[SPEAKER_02]: There is also evidence of just that the Hawaiian tiger sharks are genetically different as well.
[SPEAKER_02]: So this is still under research, whether there's one species two or three species of the tiger shark alive today, subspecies.
[SPEAKER_02]: So that's, it's not quite even there yet, the subspecies level.
[SPEAKER_02]: So subspecies, they get the third scientific name.
[SPEAKER_02]: It means that they are partially genetically distinct, but do interbreed with the main populations.
[SPEAKER_01]: Okay, okay.
[SPEAKER_02]: Which could be probably more likely, for example, the Hawaiian variety, because the Indo-Pacific one will run into them every once in a while and probably breed.
[SPEAKER_02]: Okay.
[SPEAKER_02]: So while they do, I mean, maybe isolate a little bit.
[SPEAKER_02]: They're not extremely isolated like the Pacific and the Atlantic.
[SPEAKER_01]: Would they produce something with what's it called a hybrid vigor?
[SPEAKER_01]: Probably not because they're probably still closely related enough where they're.
[SPEAKER_01]: If you see 90 foot Tigers.
[SPEAKER_01]: Yeah, that gets the really big.
[SPEAKER_02]: But yeah, that's been the Tiger Shark.
[SPEAKER_02]: It's been a long, it's a little bit longer one.
[SPEAKER_02]: Sorry.
[SPEAKER_01]: Yeah, I mean, a lot of information on these guys.
[SPEAKER_02]: I like Tiger sharks.
[SPEAKER_02]: They're really cool.
[SPEAKER_02]: This is definitely an animal to see from afar.
[SPEAKER_02]: There are zoo or aquariums that have them.
[SPEAKER_02]: So bull sharks and type, no, nobody has a great way shark, I believe right now.
[SPEAKER_02]: It's been tried several times.
[SPEAKER_02]: They just don't do good because they're open ocean animals.
[SPEAKER_02]: uh, they need space.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: And they're, they're food.
[SPEAKER_02]: They amount of food.
[SPEAKER_02]: They are consuming and everything like that.
[SPEAKER_02]: You need like a band-tum, uh, great white shark.
[SPEAKER_02]: Uh, so there are a couple, like, uh, salmon sharks, uh, or like smaller, great whites.
[SPEAKER_02]: There are a couple great whites, relatives that are smaller, the band-um varieties.
[SPEAKER_02]: Yeah, I wouldn't say, small relative, right?
[SPEAKER_01]: Yeah.
[SPEAKER_02]: When your cousin is 22 feet long and 8,000 pounds, right?
[SPEAKER_01]: Yeah.
[SPEAKER_02]: Small,
[SPEAKER_01]: Right to the shark.
[SPEAKER_02]: Yeah, a pan of whale shark would be really cool.
[SPEAKER_01]: That would be sweet.
[SPEAKER_01]: If they got like four feet long, I'd have I'd have a aquarium of those.
[SPEAKER_01]: That'd be cool having like in a coy pond the backyard.
[SPEAKER_01]: You know, the feeding like the catfish and the coy, you know, cat food or whatever.
[SPEAKER_01]: And then a little whale shark just comes over and scoops up the rest.
[SPEAKER_02]: But yeah, so what do you think of these guys?
[SPEAKER_01]: Other really neat.
[SPEAKER_01]: I would just thought they were, you know, just big, uh, teeth, razor, filled terror machines that would want to eat your ankles and they're very, very curious.
[SPEAKER_02]: And, uh, that's where I guess a lot of human interactions come from, and then humans do not act appropriately when that's happened because they do the price, they they panic and splash and yeah, it excites the tiger shark.
[SPEAKER_02]: If you see a lot of professional divers that are around
[SPEAKER_02]: they just don't move.
[SPEAKER_02]: But they're that or they move around with them and they'll even like some people which I don't advise will touch them and stuff like that.
[SPEAKER_02]: Some like the professional shark drivers.
[SPEAKER_02]: Yeah.
[SPEAKER_02]: Uh, they'll be at, yeah, this female, you'll be doing this for 30 years or they're, and yeah, they don't, they don't get bit, you know, they're not dumb animals.
[SPEAKER_01]: Yeah, you can, when you're with them enough, you can read them.
[SPEAKER_01]: It's just like a dog.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: You know, if you run dogs enough, you know, and it's like blue isn't the one that's, which is a great way that's famous for people diving with.
[SPEAKER_01]: Yeah.
[SPEAKER_02]: Uh, and then long as you're smart with her, she's never bitten anybody.
[SPEAKER_01]: Like I said, you just got read the animals and I think cats dogs don't matter.
[SPEAKER_01]: If it fits panic, and it doesn't want to be touched and you're over there touching it, it's going to do something.
[SPEAKER_01]: Whether it's going to bite your words kind of like, you know, run away or something, but most likely they're, they bite.
[SPEAKER_02]: Well, I have been the great and peaceful mystery, and I've been Jay.
[SPEAKER_01]: Catch you next week, guys.
[SPEAKER_01]: Bye.
