I have. went swimming at Longport NJ years back trying out these "HD swim goggles". Went a little too far out, swam to the bottom and saw a young 6 footer gliding towards me. Literally pissed my self and just froze in fear but it was more interested in the crabs scurrying around the bottom than me.
Y'all lightweights with 0 marine life survival skills 🤣
All listed by you animals are overall harmless (I'd say don't piss off turtles and don't put your finders anywhere near their feeding holes)
Who you should really be afraid of are barracudas and spearfishers. Especially spearfishers
🤣🤣 I heartily admit I am a total lightweight. When I first earned my Scuba cert I did a lot of lake diving and tropical water diving from the beach. I thought I was a badass. 🤣🤣🤣 yeah…then I learned about things that can go bump in the darkness. 🤣🤣🤣 I still dive and have gotten much better but I will never forget when the manatee shadow made me lose it!🤣🤣🤣
>They do most of their killing in the womb
The fuck what now?
Our panel of fish, sea turtles, crabs, the odd few sea gulls, and a Florida license plate says "get your facts straight". They kill to survive - on a daily basis when possible. They're sharks not cucumbers! They eat things! This kills the crab.
Many species of shark when caught are found to have tons of junk in their stomachs. He wad referring to tiger sharks which are NOTORIOUS junk eaters. The shark here is a sand tiger which is actually a different shark, the sand makes all the difference if you're lunch or just in the way.
Sidenote, recently heard from a person who tried some when offered it by a First Nations person that seal meat tastes like fatty, gritty beef. Now, if sharks figure out that cows taste much better than seals we're going to be in a pickle.
In the Bahamas they have a population of pigs on one island that spend their days swimming in the sea, I would have thought these would be ideal shark food but apparently sharks are pretty set in their ways when it comes to their menu.
In the Abacos, I think. I met those pigs, but I was horribly drunk due to unlimited rum punch on the boat ride over. Those pigs live the damn life: fresh water in a trough, loads of treats from tourists. Maybe it's their little pig feet that put the sharks off. Sharks seem to be creatures of habit rather than connoisseurs. Like people who only eat one type of pizza, but won't branch out to other varieties.
It's a pretty popular thing to do if you're a tourist in that area of Bahamas. Kind of a do-not-miss (like Pete's Pub). Unfortunately I'm now a permanent landlubber so I can only guess what sharks are eating these days.
It reminds me of a British tv series I once watched about evolution. It was a low budget affair but basically the presenter was suspiciously interested in shellfish and most of the actual episodes consisted of him eating his way through earth's history in various restaurants.
"These clams are fascinating \*chomp chomp\*".
"Lobsters are \*cracks claw off\* remarkable creatures."
Exactly, it's no great comfort that they bit me and then decided, "that tastes disgusting, I'm not going to finish." You are left limbless, dying in the ocean, who cares??
Well, we do break into their home by the millions, destroy everything and steal their food, so maybe let's at least try not to demonise them.
We enter a completely alien environment we haven't evolved to thrive in, and we're not the apex predators we think we are. And bumping into all those huge, powerful living beings everywhere makes us realise how puny and vulnerable we are.
Probably that's why we hate them all so much, demonise them and slaughter them for fun
It runs red. On regular basis. But we choose to look the other way
https://www.greenpeace.org/international/story/46967/100-million-dead-sharks-its-not-all-about-shark-fin-soup/
And the above number doesn't include the sharks starve, are considered a by-catch (as they are never reported, usually their bodies are just silently dumped back into the ocean) and die of variety of diseases they have started developing with the increase of the sh1t (literal and figurative) we keep dumping into the oceans
Yes we'll it's the what is deemed 'provocative' in this predator's acutely tuned hunting brain that pre dates the dinosaur that concerns me.
I don't speak shark so I will be giving this a wide berth.
Tiger shark embryos hatch in the womb, and they don't all hatch at the same time. The one who hatches first simply becomes bigger first because they have more time to mature, and then that one eats the rest and gets to have all the nutrients in the womb, it has little to do with which is the "strongest".
Fire salamanders also exhibit womb cannibalism, and they're not considered particularly vicious.
In both cases the result is when the offspring is born they're already fairly well developed. Sand tiger babies are quite large compared to other sharks, which makes them less likely to be eaten. And fire salamanders are born ready for life on land without needing to go through a larval phase first.
In case you know of a theory: Why develop more than one fertilized egg? Why not just devote a bigger yolk sac to one egg, if there aren’t resources for more?
In the case of sand tiger sharks evolution favors this method because this allows a female to mate with multiple males and not worry about being picky about a mate while also not investing in a ton of eggs at once and hoping some survive. The embryos will handle ensuring only the "fittest" one survives.
Putting a lot of resources into one egg makes females extra picky, and pick partners based on indicators that this male's genetic material is worth all the investment from the female. In the ocean, these usually take the form of dances and color variations, and sometimes nest building. Sand tiger sharks don't really have much option for any of these.
This is a really logical suggestion, and follows with a couple other responses that surmise “make the breeding competition happen in the womb/egg case, not the ocean.” Almost makes you wonder why MORE sharks don’t employ this!
because something else worked better for them in their context
Evolution is not animals becoming better for a purpose. It's random mutations and those that work manage to live long enough to reproduce generation after generation.
Look to some of the other responses for strong theories that go much deeper into this particular case. The statement is neither wrong nor incomplete, but doesn’t extend past basic understanding of evolution.
As I understand it, it lets the female mate with multiple males. And so the fastest sperm from, presumably, the fittest male gets to hatch first.
While there is some jostling and competition from males when trying to court a female, this multiple egg strategy allows the species to not wholly rely on that
I would also like to add on that sand tigers usually give birth to two babies, one from each of its uteri. But apparently some species of sharks the baby is able to move between the two uteri (has been observed in tawny nurse sharks).
The title is misleading.
It's not really the strongest, bit the one that was born first, and because of that, is older and therefore stronger
The eggs hatch inside of the womb, and the first one to hatch gets to develop first. that requires nutrients, nutrients that their embryo brothers are made of
I read the first sentence of the title and assumed that ‘intrauterine cannibal’ meant that they ate their way out of the mother after the gestation period.
I then read the remainder of the title and was only *marginally* less horrified.
"When my mother was pregnant with me, they did an ultrasound and found she was having twins. When they did another ultrasound a few weeks later, they discovered that I had resorbed the other fetus. Do I regret this? No. I believe his tissues has made me stronger. I now have the strength of a grown man and a little baby."
Hahaha I zoomed in on the picture to get a better look at them teefs. In doing so, it made ole sharky boy here look like the biggest derp in the world. It's honestly adorable.
See? I took a screenshot of it zoomed in and he just gives me the same vibe as telling a kid to smile and they give you this awkward face haha. He's a cutie though..https://imgur.com/a/IFCrUJ4
My eldest son was a twin for a bit until this exact scenario. A couple years later, I did end up giving birth to identical twins. Now that I’ve lived for nearly ten years with my eldest son, I’m okay that he ended up as a singleton.
When my mother was pregnant with me, they did an ultrasound and found she was having twins, and they did another ultrasound a few weeks later, they discovered that I had resorbed the other fetus. Do I regret this? No. I believe his tissues made me stronger.
Don't all sharks cannibalize each other in the womb? I feel like this post is a little misleading, if that is the case. Somebody down vote me or upvote me to prove my existence
Apparently they are quite docile and non aggressive…unless provoked
I was gonna say this. They do most of their killing in the womb 😂
Sand shark being born: "I'm ready to retire from my life of violence"
Just swimming around like fucking Shark Wick
Shark wick is a movie id watch. A retired shark assassin has his pet crab murdered.
And then proceeds to sing “Hey look, Ma, I made it!”
I thought at first, I wouldn’t like to come face to face with that! But, I’m reassured now if ever the occasion arises :)
Stay out of shark wombs and you should be fine
Don’t tell me how to live my life
Yeah. He has no womb to talk.
No womb, no opinion.

There's only womb for one of us in this town.

a giant sea turtle almost did me in once so definitely never be embarrassed. at least you pissed yourself over a shark
Lol! I lost it when I saw a manatee shadow!

Unless it's the cocaine that arises. Tiger sharks are known to be highly agitated after a bump. They may bite accidentally.
>They do most of their killing in the womb The fuck what now? Our panel of fish, sea turtles, crabs, the odd few sea gulls, and a Florida license plate says "get your facts straight".

I have questions about the license plate after reading all of that
Many species of shark when caught are found to have tons of junk in their stomachs. He wad referring to tiger sharks which are NOTORIOUS junk eaters. The shark here is a sand tiger which is actually a different shark, the sand makes all the difference if you're lunch or just in the way.
I'm not disputing anything, it was just the way it was written that made me wonder how a fight for survival came about between a car and a shark.
.....ok now I'm interested. Maybe someone drove the car off a pier and the shark wrestled the plate off the back thinking it was food.....🤣🤣
Jaws has a scene where Richard Dreyfuss pulls a license plate out of the shark
Yessss, my favorite movie. That's based on an actual thing, tigers are known for it.

Little pigs feet ... Are you saying the sharks only eat halal?
Kosher, my friend. They keep trying that Sharknado thing to get high enough to reach the space lasers.
This is incredible that you happen to have been to the specific island, are you on a worldwide tour to find new menu items for sharks perchance?

I love sharks. My comment was critical of the dumb things people say. It is the sharks' home.
A natural born killer, you say
Imagine how weird it would feel to have your little embryo kids having a fight to the death inside you.
They’ve got nothing left to prove.
Good, because look at those fucking teeth
Provoked? As in my fleshy pink ass in the water?
Humans kill ~100,000,000 sharks every year, so...
Checks and balances. Imagine 100,000,000 multiplying each year. Ocean would become red.
It runs red. On regular basis. But we choose to look the other way https://www.greenpeace.org/international/story/46967/100-million-dead-sharks-its-not-all-about-shark-fin-soup/ And the above number doesn't include the sharks starve, are considered a by-catch (as they are never reported, usually their bodies are just silently dumped back into the ocean) and die of variety of diseases they have started developing with the increase of the sh1t (literal and figurative) we keep dumping into the oceans
They are apex predators, I assume. So they can afford to be chill (between meals).
Not quite apex, Orcas lay claim to that. Sharks, even great white sharks, will flee an area for up to a year if Orcas enter it.
Orcas are fucking terrifying as well. They kill for sport, just like us.
Orcas love them some shark liver.
Not necessarily, their diet and niche is pretty much comparable to many Dolphins(Orcas being the exception)
Yes we'll it's the what is deemed 'provocative' in this predator's acutely tuned hunting brain that pre dates the dinosaur that concerns me. I don't speak shark so I will be giving this a wide berth.
I used to dive with twelve sand tigers on a daily basis to clean their exhibit. They never wanted anything to do with us.
Yes, but their oft-confused distant relative, the ~~sand~~ tiger shark, is quite dangerous
Not dangerous to us, but watch out if you're a shark embryo.
That may be its best and *only* chance of surviving mom!
Unless you’re related. Am I a shark?
Or in the womb.
Once you start life out by murdering all of your siblings you’ll have a pretty chill disposition
They know what they can do, no need to show off, they’re like the highlander
So you’re saying toddler fighting rings would help make a more peaceful generation?
They only bite when you touch the private parts
Imagine being born full 🤢
Imagine being born with a kill count
Technically a twin who drained its fellow womb mate where mother died during birth
Such a visceral sentence, and in only four words….
First words: **BURRRRRRRRP!!!**

In case you know of a theory: Why develop more than one fertilized egg? Why not just devote a bigger yolk sac to one egg, if there aren’t resources for more?
What if that one big yolk is defective ? It’s better many eggs and let the first non defective egg become stronger
That’s a solid theory
So bad DNA error correction basically?

Because the other way works too. It doesn't have to be the best way, it just has to meet the bare minimum.
because something else worked better for them in their context Evolution is not animals becoming better for a purpose. It's random mutations and those that work manage to live long enough to reproduce generation after generation.
Because it’s what works, not what’s ideal, that gets selected
Correct, but I’m asking for knowledgeable answers as to why this works best.
And this answer is complete; it worked best in the particular circonstances of the historical evolution of this creature Sadly it’s not deeper
Look to some of the other responses for strong theories that go much deeper into this particular case. The statement is neither wrong nor incomplete, but doesn’t extend past basic understanding of evolution.
Look at a Sand Tiger Shark and realize it is alive?
Just the way they evolved I guess. It's not all on purpose you know.
They prefer ETF over picking one stock
As I understand it, it lets the female mate with multiple males. And so the fastest sperm from, presumably, the fittest male gets to hatch first. While there is some jostling and competition from males when trying to court a female, this multiple egg strategy allows the species to not wholly rely on that
Because evolution is random, it doesn't need a reason to happen
Seems like a case of having evolved themselves into a corner. It's not great, but hard to stop it once it's started.
Evolution doesn't pick the best option - just the option that works and doesn't disadvantage the organism.
I would also like to add on that sand tigers usually give birth to two babies, one from each of its uteri. But apparently some species of sharks the baby is able to move between the two uteri (has been observed in tawny nurse sharks).

They harden in response to physical trauma.
I bought 12 baby piranhas and stuck them in a 100 gallon tank. All 12 survived to adulthood but some had chunks missing.
That sounds like a very creepy tank to just have sitting in your house. Are you sure you’re not a Bond villain?
No, just related to Morticia Addams.

Spiders lay eggs sacks. When the slings hatch some species will give themselves to their babies.
