I am going to make a thread of sharks and their wikipedia articles. Did you know I like sharks? I sure hope so.

Nurse sharks! A good floor shark. https://en.wikipedia.org/wiki/Nurse_shark#Distribution_and_habitat

Wobbegongs are also good floor sharks. They actually look like a carpet. Why they haven't made cute rugs modeled after wobbegongs I will never understand. https://en.wikipedia.org/wiki/Wobbegong 

Lemon sharks! Their name is super cute. They also like to make groups. Social sharky. https://en.wikipedia.org/wiki/Lemon_shark#Social_behavior

A shark that is a teensy bit more reasonable to be scared of (but really, REALLY, sharks do not want to eat you) but bull sharks are super cool! They're like salt? fresh? water? PSH, i'm gonna swim in it. >:( Adorable chunky sharkos. https://en.wikipedia.org/wiki/Bull_shark#Distribution_and_habitat

Zebra sharks!! Why did they name you zebra...you clearly have spots... Well, their babies have stripes and I guess people didn't want to bother changing it. But I love!! Their round!! Faces!! Another good floor shark. https://en.wikipedia.org/wiki/Zebra_shark#Description

Reef sharks! The one linked is the whitetip reef shark. Also scroll up, the first pic is adorable. But the link has a legendary shark pile shot. Reef sharks are super chill, these guys especially. I want to chill like a whitetip reef shark... https://en.wikipedia.org/wiki/Whitetip_reef_shark#Biology_and_ecology

Most people know about the filter feeding whale shark, but basking sharks also filter feed!! They have biggo mouths, but they're just chilling, filtering, swimming. https://en.wikipedia.org/wiki/Basking_shark

But yes, whale sharks are adorable. Look at them filter feed. They are (somewhat) flat and big, but not a floor shark!! https://en.wikipedia.org/wiki/Whale_shark#Diet

Greenland sharks! Some people eat them. They can live over a hundred years (wikipedia says 392 ± 120 for their oldest, so that's a huge error margin but STILL) and are full of urea, like in human pee. Maybe the secret to longevity? https://en.wikipedia.org/wiki/Greenland_shark#Physiological_adaptations
