    something to note is that while finning is absolutely still a problem that exists, the vast majority of shark deaths are due to unintentional bycatch or getting caught in ghost nets, not targeted fishing for fins. focusing on finning makes it harder for actual effective policy to be put in place (such as online petitions demanding shark finning be made illegal in the US, unaware that the practice is already illegal and has been since 2000), and also often devolves into xenophobia. "why sharks matter" by david shiffman is a great book about threats to shark and how you can support effective shark management!

      actually I don't believe bycatch is the biggest issue. There is definitely a ton of bycatch killing sharks, but I'm pretty sure the vast majority of sharks killed are the targeted fishing of the spiny dogfish that constitutes the biggest proportion of the 100million sharks killed. Only spiny dogfish have numbers high enough to barely sustain such fishing pressure, and they are fished for products in many Western countries for dog food, fertilizer, table fare, and fish oil. You're correct though that the message at the ending unfairly targets finning as the culprit.

    My favorite shark's are the Salmon sharks and the Porbeagle shark because one is like a specialized version of a great white shark/the other a large specialized mako shark. Both able to have their internal body temperature 🌡️ way above the surrounding water. Which is an INSANE capability that allows them to be way faster and agile than it's prey in the colder waters that it hunts in. It's amazing they are able to do this. That's not even including all the other amazing traits sharks have/like sensing electric pulses from creatures muscles to find prey.

    I'm being serious mind. When I hear the word shark I think of the times I've been in the water with them, swam alongside them and seen them do their thing. A creature which basic bodily shape hasn't changed all that much since the Devonian period some 400 million years ago. A sleak, powerful, efficient and effective predator that survives. Whether it be Stethacanthus some 400 million years ago, or megalodon or the great white which I've seen up close in person in open water or any other species of shark past, present or future. They'll still continue to be amazing creatures and that's why I like them, I respect them.

    By the way it’s theorized that stethocanthus aka the island boarding shark wasn’t actually a shark but was part of a different group of cartilaginous fish called the chimeras. There’s still a few members of this group of fish alive today like the elephant fish and the rat fish.

    I like that you made sure to note that most of the Carboniferous and Permian “sharks” were not really sharks but stem-chimaeras, but but this is also the case for Cladoselache, which you identify as a “true shark”. Come to think of it, the fact that so many of the earlier fish in this video aren’t sharks makes me think it could’ve just covered the full history of cartilaginous fish, rays and true chimaeras included.

    Something interesting is early sharks had to stay small and nimble to out maneuver the bigger predators of the Devonian like Dunkleostious and Hyneria. Kind made me start sensing a pattern. Something starts off small to avoid bigger threats and when those threats are gone they explode into a variety of forms. Sound familiar?

    • @AncientCreature-i2o

      Actually, increases in size has been directly correlated to an increase in predation and predator size. So growing larger is absolutely a defensive evolutionary trait.

      @TheSandwhichman108 2 года назад

      @@AncientCreature-i2o well bigger isn’t always better I mean look at early mammals for example. They had to stay small to avoid being eaten. Early sharks most likely had to do the same because of the bigger predators. Plus being small has its advantages. You can hide in places nothing else can get you in. You can be faster and your body demands less fuel to keep going.

    Always fascinating; sharks. Long before the movie Jaws, and the book 'The Old Man & the Sea', Sharks have been an issue to Sea Faring peoples.
    Sharks have been getting killed on site, BEFORE man knew there were so many different species.
    Fishermen, proud to have reeled in a 10' Great White, we now know was just a juvenile shark. It makes me wonder, if humans didn't nearly decimate the Great Whites, would they & the Meg turn out to be one-&-the same? Is Megaledon a fully mature Great White?
    I will always wonder.
