Dolphins Sleep With One Eye Open

How do dolphins sleep?

Dolphins sleep only with one half of their brain at a time. Dolphins are conscious breathers. Should they sleep and go unconscious as we do they would simply suffocate or drown. Sleeping dolphins can be seen as resting, floating at the surface, with one eye open. After a time, they will close the one eye and open the other one. They alternate like this throughout their entire nap.

Watching a dolphin sleep isn’t exactly the most exciting thing to see but nether the less, here it is.
