Did you guys know that the most recent version of sharks have fins that are kinda leg like and they like to walk up onto land?

no way i must have missed an update!

The Epaulette shark is only about 9 million years old as a species, making it the most recent branch in the shark family. And it is slowly but surely evolving into a land animal

Shark Enjoying some sea grass.......

alex51324

I 100% had no idea that sea grass looked that much like, y’know, grass.  

I do not know what I would have guessed it looked like, had anyone asked me to do so, but my answer would definitely have been Less Like Grass Than That.  

Also it is adorable that sharks like to roll in the grass like horses.

Also best not to pet sharks without gloves. Their skin can really tear up ours with lots of petting.

yeah, this is what sharkskin looks like under a microscope:

it’s covered with tiny interlocking teeth that form a one-way-only surface! petting a shark the wrong way will literally make you bleed, which is still never a thing you want to do if you are in the water with a shark.

(yes, those are literally teeth-sharks ended up evolving a skin covering completely separate from the scales that bony fish ran with and they did it by mutating the teeth out of their fucking mouths and over their entire surface area)

Being internet-shitpost-aware means that you know damn well that this post is a dread summoning spell

Amazing how they still manage to be perfectly smooth while covered in literal teeth

What colors can sharks see?

bunjywunjy answered:

sharks actually can’t see any colors at all!

they’re colorblind in the truest sense of the word- shark eyes have NO cone cells to work with, only light-sensitive rod cells! 

image

so sharks still have excellent vision especially in low-light conditions, but they see the world only as the presence or absence of light with no concept of color.

Does that mean only black and white, in simple terms?

bunjywunjy

what we call “black” is a function of being able to process the absence of color, and a shark’s visual experience would be different since it’s coming from a different place altogether. I don’t know if humans would be able to conceptualize how a shark sees the world at all, especially once you throw their electrical sense in there!

I've thought about this a lot and I think I may be close here.


What we see

What sharks see. They'd get a distortion around the fish or other shark because of the electrical field. You can pick up immediately what it is in shape and reflected light from its skin. It stands out compared to the darker background but its not easy to tell exact species. Would also describe why surfers get nipped on boards, sharks thinking they're other animals.

that's a cool theory! now we just need to spin it for the grant committee
