Do Dolphins Sleep with One Eye Open?

Answer

Dolphins normally sleep only with half of their brain at a time. This is due to the fact that dolphins are conscious breathers, if they sleep and go unconscious, they would simply suffocate or drown. This is why sleeping dolphins are seen as resting, floating with one eye open at the surface.

Dolphins sleep with only one hemisphere of their brains in a resting state. This allows them to maintain enough conciousness to breathe and watch for possible threats.
In captivity, dolphins enter a full sleep state. A tail kick reflex keeps their blowholes above water, allowing them to breathe.
