Question

Why did Dolphins open there one eye when they are sleeping​

Answer 1

Explanation:

• Because they need to periodically come up for air and keep an eye out for potential predators, dolphins can't curl up and zonk out at night like land mammals can. ... So they must stay somewhat conscious and sleep with the proverbial one eye open.

Answer 2

Answer:

Dolphins cannot sleep in this way; they have to remain conscious, even when they are sleeping. This is because their breathing is not automatic, it is consciously controlled.Dolphins only close one eye when they sleep; the left eye will be closed when the right half of the brain sleeps, and vice versa.
