Do sea animals ever go to asleep like fishes and sharks?

And if they do, how would you know?

Not ALL animals need to sleep. Animals with brains USUALLY need to sleep

Fish do indeed need to sleep.

Jellyfish, coral, sponges, sea cucumbers, zooplankton, krill, clams, sea stars… these are all animals and they never sleep.
