@@ghostshirt1984 he said nothing about humans or endangered . There is nothing to disagree about. They are resilient, dont think you understood what he wrote
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.
Thank you for an educational, honest video on sharks! I especially appreciate the nice calm voice. So many animal videos have spastic narrators and obnoxious "music"!
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.
The Habsburgs of predatory animals for sure. Not always on top but surviving and abiding their time until it is their chance again to be on top of the food chain.
Sharks are almost Second Fiddle to other animals from the Devonian with the Armored Fish through the Mesozoic with the Marine Reptiles and now in the Cenozoic with Mammals. Even Megalodon had stiff competition from Whales. I feel kinda sad for them. Still a Great Video and Great Job! :)
This is an excellent and accurate documentary. Thank you! I collect fossil shark teeth, vertebrae and so forth. It's fascinating to see how they evolved and diversified over hundreds of milions of years.
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?
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.
@@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.
Maybe there is a simple answer for this. If sharks have no bones, therefore no body parts to fossilize, how can certain weird body features be determined?
I know it’s really unlikely, but with megalodon, I kind of wish scientists would eventually discover that it was actually just a couple inches long, but with a BIG-ass mouth, lol. Not sure why, but that would be the funniest shit…. The mental image is ridiculous, haha
Very interesting video. Unfortunately, your narrator's voice would be better reading bedtime stories to kids. Listening to this video came close to putting me to sleep.
Helicoprion has to be one of the weirdest extinct sharks. Species of sharks on earth today, I would say Goblin sharks and Cookie Cutter sharks are very weird. My favorite is still the Great White (beautiful looking sharks and Apex predator)
Sharks. Broca's area, or the Broca area is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production. 2/8/2021 and I lived again. Broca's aphasia (non-fluent aphasia) Mike Caputo, Year 1 Stroke Recovery, Up Up Up - Aphasia with attitude, Broca's Aphasia, Right-side Weakness, Mark's 22 years-old Stroke: Broca's Aphasia.
Interesting: the truly oddball fish shown at :56 seconds in (the one who looks like a political caricature) is a Mola, or Sunfish--a bony fish. NOT a member of the shark taxa. (I think the camera was trying to show a shark farther away and above, but the cameraperson got distracted by the attractive Sunfish weirdness!) Also, the narrator comments on the remarkable diversity of sharks being around "before vertebrate life" made it on to land. True; but they were thriving before MULTICELLULAR life made it on to land! (And now I'm off to top up my pedantry!)
Plus, I wonder how much science REALLY knows about the appearance of certain sharks. As everyone know they didn't had a bone skeleton, so mostly they've found teeth. I always was laughing inside by thinking all the Megalodon teeth did belong to a shark, that wasn't nearly as big, but had a very broad and big mouth instead...
Think for a second about what's the coolest looking land animal...Peacock...Giraffe...Spider.. Now what about ocean animals...Octopus...King Crab...etc...but the coolest HAS TO BE THE HAMMERHEAD SHARK
While cartilage doesn’t fossilize well, it DOES happen! Otherwise, there’d be no soft body fossils at all and we’d know nothing about a lot of prehistoric animals - such as what we have from the Cambrian explosion (burgess shales, for example). Many things need to be juuust right for those non-bones to fossilize, though.
@@TheaSvendsen not disagreeing with you, but many soft body fossils are what they call compression fossil or a negative fossil if im not misstaken? Basically a mold of the creature and not the creature itself.
Ref to the quote at the end, that sharks has been painted as a mindless killer. The ONLY "mindless killer " creature/life form to ever to exist on this planet. Throughout the entire history of life.. human beings aka Homo sapiens
All the magnificent natural history of sharks will unfortunately but undoubtedly be snuffed out because of our desire for a bowl of soup!how very sad 😢
Sharks are the most resilient things in nature next to crocodiles. They both survived several mass extinctions and evolved.
I disagree! With people here on earth! Sharks are now endangered species.

Wait so if the finners try fish for something else entirely, they'll catch even more sharks?
Seems counter intuitive.
@@xengen212 No, there's just much more fishing that targets other species
