What is the only animal that never sleeps?

Some people think that sharks never sleep because they need to keep moving in order to breathe. However, some sharks need to keep moving to do this, while others don't. Some sharks have spiracles, a small opening behind their eyes, that force water across the shark's gills so the shark can rest. Other sharks do need to swim constantly to keep water moving over their gills and their bodies, but sharks can swim without using all of their brains. These sharks have active periods, and restful periods, rather than undergoing deep sleep like we do. They seem to be sleep-swimming, with parts of their brain resting.

Do sharks sleep, and if so, how do they do it?

Yes, sharks do sleep, but in a different way than humans. Sharks do not have eyelids, so they cannot close their eyes while sleeping. Instead, some sharks have to keep swimming to keep water flowing over their gills for oxygen. This is called "active rest." Other sharks can rest on the ocean floor or in a cave while still moving water over their gills to breathe.
