How Did Sharks Survive So Many Mass Extinctions? 

Even if Sharks were completely extinct, some fish species will gradually carbon copy the same body plan to fill that niche. Assuming a supernova or other planet ending phenomenon doesn't intervene.

Sharks have changed and diversified morphologically by a huge amount.

Also turtles and lizards

And Tardigrades.

Agree. It'd be awesome to see a Paleo sound composer make accurate noises of some prehistoric animals depicted to look even more lively.

Even paleo art proven to be anatomically incorrect, and speculative art have incredible merit. Art in all its forms is one of the most important parts of our civilization.

It's actually really sad that cartilage doesn't fossilize well. Although I respect paleoartist, and love their work, i find it sad that 99% of all reconstructions of sharks are the same fisk with different jaws. That is the grate white form. If we can learn anything about sharks knowing current species, it is that sharks are really diverse and magnificent.

There are several accounts on Instagram which showcase paleo-artist works.

The only one who is somewhat famous is James Gurney. His work, such as Dinotopia, are just as genius as any other art.

And that crocs are unbelievably lazy , I had a large alligator in a ditch in my backyard that did not eat anything significant or move much for a year and a half because of a harsh winter that screwed up his mating season migration before finally leaving without much apparent weight loss. Crocodilians can just shut off during rough times in a way that puts bears hibernate to shame

@@voiceofreason2674 yes, they slow down their metabolism. The cold aids in slowing down their metabolism as well. Crocodilians have a metabolism that basically runs off the temperature around them, the complete opposite of us mammals. If it’s hot out, crocodilians would have to eat a lot more, whereas in the cold their metabolism the metabolism itself can’t digest food fast. Us mammals have constant metabolisms based off our body temperatures, that’s why most people have the same metabolism.

Sharks can just eat each other and boom, easy

@@bunathan2485 Need more food? Give birth.

@@bunathan2485 yes, sharks are known cannibals as well. A lot of animals that have been alive for very long time just seem to be animals that are omnivores and scavengers. They have learned to eat anything while others learned to eat very specific things, like koalas and mantis shrimp. Those animals can very easily be wiped out with just a loss to their food source. This can happen to humans as well though, we have a wide variety of foods but we have not adapted to being able to eat anything and everything. Eating different kinds of lettuces and tomatoes and different species of cows and chickens doesn’t mean we can eat anything, it means we’ve created a variety.

Even megalodon lasted over 15 million years (and even managed to outlast competition from the raptorial sperm whales or other raptorial odontocetes). Most apex predators are lucky to last 5 million years.

Except macropredatory condrichtians did get slapped pretty hard in all major extinctions. Eugeonotids became nearly extinct in the P-Tr extinction and Lamnids never recovered from the K-Pg extinction.

@@miquelescribanoivars5049 Lamnids became more successful post-KT than before.

@@bkjeong4302 Larger =/= More sucessfull. They were 60 to 90 genera of Lamniformes in the Late Cretaceous, they never reached that diversity in the Cenozoic and it has kept decreasing until this day. This research is referenced in the video.

@@miquelescribanoivars5049 I’m not talking about size. In terms of eco-morphological diversity lamniforms did (and still do) better in the Cenozoic than the Cretaceous. You’re also ignoring that those 60 to 90 genera didn’t all live at the same time.

turtles being immune to jellyfish stingers has proven to be a very advantageous adaption. jellyfish are some of the oldest marine species to exist and they are still thriving - its an abundant food source that doesnt seem to be dwindling. As long as turtles can survive their vulnerable early life they should be fine..... assuming acidic oceans don't destroy their shells.

Futile trying to merge cladistic and Linnean classification - Linnean ranks are falling out of favour (at least among professionals). Chondrichthyes and Osteichthyes are universally considered monophyletic clades under all current schemes.

A classification of six living classes of vertebrates called fish seems to make more sense, with lampreys being more closely related to jawed vertebrates than to hagfish, Elasmobranchs being more closely related to bony vertebrates than to holocephalans, and lobe-finned fish being more closely related to tetrapods than to ray-finned fish, therefore this redivides fish into the classes: Myxini (Hagfish), Petromyzontida (Lampreys), Holocephali (Chimaeras), Elasmobranchii (Sharks and Batoids), Actinopterygii (Ray-Finned Fish), and Sarcopterygii (Lobe-Finned Fish), these taxa were traditionally ranked as subclasses, but were revised as separate classes from each other, therefore making the former taxa Cyclostomata, Chondrichthyes, and Osteichthyes paraphyletic.

Sharks aren't near extinction. There are a select few subspecies of ground sharks that are all found off the coast of Africa. Do you want to tell poor African they should stop fishing?

@@c_f0rce If you look at the trends of all sharks populations over time, you'd see that their populations are drastically going down. If apex predators populations are brought down too much or if they are made extinct that has a catastrophic effect of the ecosystem. Overfishing, climate change, ocean acidification migration patterns changing and many other causes are making it so sharks overall are going extinct.

I think, so long as we can remind people of the importance of sharks, they'll always have a chance. Sadly we'll never be rid of something so daft as shark fin soup and its made up medical benefits, but we can push for sustainable harvesting and more laws regarding bycatch prevention.

"How can someone enjoy his or her burger when it is known how the meat is "harvested". Obviously it's different but the wording used in your comment bothered me. I agree that sharks shouldn't be killed without restriction (there should be a hunting season or something). But outright banning killing sharks is dumb. There are plenty of fish we kill in massive quantities but you wouldn't give a damn about them, probably just because "there are more of them." or something. Sorry, something about your comment rubbed me the wrong way and I couldn't say nothing.

@@resurrectedhelicoprion maybe, but usually fish with large populations greatly benefit the ecosystem as they give a lot of food and sometimes symbiotic relationships to local predators. (I also love ur profile name. The helicoprion is one of my favorite extinct sharks)

'Conan the Bacterium' . *Deinococcus radiodurans* // ... An extremophilic bacterium and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a *polyextremophile.* It has been listed as the world's toughest known bacterium in The Guinness Book Of World Records. The name *Deinococcus radiodurans* derives from the Ancient Greek δεινός (deinos) and κόκκος (kokkos) meaning "terrible grain/berry" and the Latin radius and durare, meaning "radiation surviving". The species was formerly called Micrococcus radiodurans. As a consequence of its hardiness, it has been nicknamed “Conan the Bacterium”, in reference to Conan the Barbarian. *Resistance to ionising radiation* *D. radiodurans* is capable of withstanding an acute dose of 5,000 grays (Gy), or 500,000 rad, of ionizing radiation with almost no loss of viability, and an acute dose of 15,000 Gy with 37% viability. A dose of 5,000 Gy is estimated to introduce several hundred double-strand breaks (DSBs) into the organism's DNA (~0.005 DSB/Gy/Mbp (haploid genome)). For comparison, a chest X-ray or Apollo mission involves about 1 mGy, 5 Gy can kill a human, 200-800 Gy will kill E. coli, and more than 4,000 Gy will kill the radiation-resistant tardigrade. // . en.wikipedia.org/wiki/Deinococcus_radiodurans
