And if you haven’t had enough ocean creature facts for one day, head over to listen to our new podcast episode “Deciphering the Mind of the Octopus” on Nebula. It will take you behind the scenes on what it’s like to take care of these mischievous animals. This is probably my favorite episode yet!  nebula.app/modulus

That footage of the finless shark plummeting to the sea floor was appalling. I'm incredibly glad you showed it, but it's appalling. I'm not outright against the killing of animals, but the combination of outright cruelty and waste is just mind bending. I struggle with how humans can so easily disconnect from certain realities (I struggle with how I see it in myself as well). A fisherman would know that these sharks would still be alive when they're thrown back in, if they just stopped to even think about what they're doing. If they're hellbent on wasting the rest of the shark, just slit the damn thing's throat before you throw it back, you sick fuck

Lobsters most definitely DO feel pain. Old (19th century maybe?) whalers reports mention the wailing moans and cries of agony as sperm whales were caught and processed on the ships, and that dealing with THAT was one of the hardest parts of the job. And for what? Fucking OIL to fuel fucking LAMPS. Thank god oil (petroleum) extraction and processing came right along, to fill the gap until eletric powered public and home lighting became a thing. Humans are capable of any atrocities given the right circunstances - against anyone, and everyone. And I’m pretty sure we committed most of them. And it doesn’t have to be much: it is not hard to imagine a fisherman ou whaler performing their job disconnected from the morality of it, just as a meat packing plant worker, for that most needed paycheck. We suck.

@furthings Год назад

@@jangofett9083 There are studies being done on it because humans are still unsure. From some studies I've read about, I think they do. Even if you don't know whether they do or not, why risk torturing them anyways? It's equally as cruel as not caring, if not worse.

@skychaserthedragon2046 Год назад

The predator/prey eye placement thing is actually tenuous at best. Eye placement is more of a cost/benefit thing. In the ocean, threats can come at you from any direction, so having binocular vision is less bebeficial than seeing as much as possible.

Y'know, I love sharks and nature and all the cool stuff it produces, but at the same time, the idea that we humans might actually be the ones to game-end them is kinda impressive. Like these things have survived everything, asteroid impacts, super volcanos, ice-ages, massive changes to their environments, and just about every other top-tier species the ocean can produce. With having endured all that, It's crazy to think that a bunch of anxious apes with fancy sticks are their biggest threat to date. Really puts into perspective how nature doesn't pick favorites.

Just a slight correction, Eugeneodontida and Stethacanthus were not sharks! They fall into the holocephali subclass, which is only somewhat related to elasmobranches (sharks and rays). I study holocephali, and it's a pet peeve of mine when people say that Chimaeras (the only extant holocephali), stethacanthus, or helicoprion are sharks

@yeasstt Год назад

If you want an extant species related to those 2 (and also Falcatus, which is another holocephali species) look at the plough nosed chimaeras! They have weird head shapes too!

@arieltarrand834 2 года назад

Wonderful video and I appreciate the level of detail. You mention hydrodynamics in terms of lift, but not the incredible sideways maneuverability. The shape of the cephalofoil allows hammerheads to turn on a dime, faster than other sharks, which helps them hunt their erratic bottom-dwelling prey. I also suspect that having the ampullae of lorenzini spread out over a wider distance aids in directional sensing, the same way having two nostrils or two ears helps us determine what direction a stimulus is coming from. A hammerhead should be able to pinpoint the direction of the electrical signal with greater accuracy than a pointy-headed shark.
