because not saying all sharks do but it's the aggressive behavior they shown towards humans and other sea creatures. I have to say a bull shark and a tiger shark would most likely attack a human just based on their behavior
@@@milesfrisby1928 People are ignorant, period. Sharks detect your heart rate and then respond to it. Their prey animals' heart rate does the same thing as ours often do when close to sharks, and that is why they sometimes attack people. Your fear is what excites them. In truth, sharks are particular feeders. Most eat fish and some eat seals. So with sharks like bull sharks or tiger sharks you defintely want to avoid looking like a fish. And with great whites you really don't want to look like a seal for any reason, for example by paddling on a surfboard at the surface. Because that is their natural prey. What happens in most shark attacks, of which there are very, very few, is that they bite more to figure out what you are and if you are a fish to be eaten than to actually eat you. Great white attacks are a little more dramatic, if even rarer, because they are ambush predators that can do great damage to a human even if it makes a mistake. But, once the shark realizes its mistake and that you were not actually a fish or a seal they will retreat and leave you to either swim back to shore or die from blood loss. A great white does not want to eat people. It wants to eat seals. When it realizes that a human they have bit is not a seal it never eats them. Like I said: I blame Steven Spielberg. Evil, man eating sharks with vendettas against people only exist in his horrible movie. But people are dumb and believe what they see I guess.
@@Fireshark I like the peaceful ones best. Whale sharks and basking sharks. A basking shark actually once swam into me off the coast of Norway. Luckily they swim slowly and don't really have teeth, but man was it big. It was like a swimming bus, and it gave me a large bruise on my leg just from ramming me very slowly. Never seen one before or since in real life. If you want to learn more about shark senses and behavior, there was a French biologist who did a lot of reasearch on why sharks bite. I can't remember his name, but he made a documentary which was partly his research and partly why sharks were endangered because Chinese people want to eat of their fins. Not sure if it can stil be found, but it was amazing. He started with normal, 2 meter sharks and by keeping his heart rate low he was able to basically pet them like dogs. But he quickly worked his way up with tiger sharks, hammerheads and finally great whites. The dude was free swimming with a great white circling around him at the end of the doc, and all he did was focus on keeping his heart rate down and not being afraid. The shark never touched him, which proves all by itself that all the Spielberg created hysteria is just that. Irrational fear based on ignorance. Sorry I can't remember the name of the man or his doc, but if you can somehow find it you should.
Otodus was nearly as terrifying as the Megalodon. It's like the Megalodon but smaller. Still, at up to 40 feet long (the max size of Whale Sharks), it is one of the gargantuan sea monsters. It proves that the prehistoric seas were FULL of giant sharks (not just Megaldon).
ototdus is a genus of mega carnivorous sharks, with megalodon being the last and largest member of this genus. The oldest living ancestor of otodus possible lived during the late cretaceous period, and it was the size of a salmon shark. Check it up!
Great Video, though Helicoprion has since been reclassified as a rat-fish, a close cousin to sharks, and some speculate it actually could have eaten shelled animals by using the whorl to grapple animals like ammonites and suck them out of the shell. In any case, a great video nonetheless!
The illustration at 5:02 - 5:07, during the showing of which you talk about "erroneous reconstructions" - thereby implying that this illustration is one such - is an illustration of a Cretoxyrhina mantelli shark from the Cretaceous, not a Megalodon. Hope that helps!
Share- aids 1- Mosasaurs didn't exist during the Megalodon's timeline. 2- The biggest Mosasaur, Pilosaurus was 10-15 feet shorter than Megalodon 3- Pilosaurus has a weaker bite force compared to the Megalodon. Megalodon>>>>>>>>>>>a Mosasaur
I would have thought the shark with the circular jaw may have had it work where it would uncurl and be used as a whip, or like an arm of a praying mantis idk
It was a very nice video but one thing confuses me. The first shark with its buzz saw teeth and megolodon both only left teeth and a select few vertebrae so how could they possibly have all the information they say they have on the second shark. If sharks preserve so badly than how could they know it had a weird find on its back or the whip like structures coming off of the other fins, how could they possibly know that only the males had them and how could they know that the shark had spike like scales on the top of the weird dorsal fin ?
I guess it depends on what you find scary. Still, if I were to come face to face with a Stethacanthus in the depths of a prehistoric ocean, I might be a little concerned. Glad you enjoyed the video anyway :)
The Megalodon's teeth size isn't scary. It is the force with which it used them. Its bite force was over 50 times of a lion and 3 times over that of a T-rex!
I can think of only one ocean predator that can singlehandedly match a Megalodon; the Livyatan melvillei. And it lived at the same time and the same place as the Megalodon, and was likely smarter.
Maybe the helicoprion had a prehensile type bottom lip? The excess teeth and flesh might have stayed rolled up when not in use. Their maybe have been a certain prey or evolution that we don’t understand yet.
I think it is an "Ammonite-cracker": Ammonites swim vertically and "backwards" and probably not very fast (relying on heavy armour rather than speed). Unless they had their eyes out on stalks therefore, they would be pretty easy prey to anything with the correct equipment to crack them from behind. This means a lot of evolutionary pressure on something to evolve to be able to exploit this food source. Next question is - would Helicoprion have held them vertically or horizontally in its mouth whilst cracking... Vertically: Pros - seems to fit shape of mouth well, bulk of edible ammonite resides in largest chamber at bottom, single row of teeth focusses all bite force to very small point on keel of ammonite, perhaps, as Helicoprion closed its mouth the action would have rotated the ammonite backwards so that as the living chamber was cracked open the teeth dragged the animal out of its shell and pushed it down the throat..., you don't have to cock your head to one side . Cons: you would be more limited in the size of ammonite that you could eat, the keel of an ammonite is probably the most heavily armoured part (perhaps there is good reason for this), a single row of teeth is more likely to slip to the right or left, unless you are very highly evolved to prevent this happening... Horizontally: Pros - you could eat bigger prey, your scissor action would be easier, Cons: eating would be pretty messy, you would just be cutting and crushing the ammonite up and somehow getting the nice bits into your throat and spitting out the nasty bits... - in conclusion then I go with the vertical assault - Helicoprion was clearly a very specialist and successful feeder - the vertical action described above seems to fit the bill much better. Then the question becomes, what do we see in the contemporary Ammonite fossil record in areas where Helicoprion was known to live ? Can we find Ammonite shells with the signature damage that this feeding method would have left behind ? If we look at the co-development of Helicoprion and Ammonites, can we see evidence of an arms race with a thickening of ammonite keels and a strengthening of the Helicoprion whorl tracking each other.... - I would be v. interested to see a detailed article on this... Someone should model a helicoprion jaw and an ammonite and do some "experimental palaeontology" to see if exactly how it worked (or didn't - maybe it ate belemnites instead :-) )
I’m pretty sure that first shark was proven to have a normal jaw, it was crushed by something and fossilized in a weird way so scientists thought it was like that at first.

Why is stethacanthus here but not cretoxyrhina? Also the helicoprion was a holocephalid

That autocorrected weirdly
Close enough
Buzz saw teeth were probably slightly retractable to aid consumption of prey through gripping g and feeding back into throat?
If animals and people lived hundreds of years before the flood it could just be a old 200 year old shark that kept growing.
If I found that shark swirled tooth structure in the south of England fossilised I'd probably ignore it, thinking it was an ammonite.
Some actually did think it was an ammonite fossil at first.
