The solution for whales and dolphins is to let one half of the brain sleep at a time. In this way, the animal is never completely unconscious, but it still gets the rest it needs. Scientists have studied this phenomenon in dolphins, using electroencephalography.

How do whales and other marine animals sleep, for that matter, without drowning? I did a little research and found out that dolphins shut down half of their brain for a couple of hours, then reverse the process and let the active side rest whilst the sleeping side awakens and takes over. This phenomenon is sometimes referred to as cat-napping.

Do whales sleep?

The answer is simple, YES they do. Their bodies shut down but only half of their mind stays at rest so that they conscientiously remember to breathe. Breathing near the surface where whales sleep allows them to breathe more conscientiously, meaning each and every breath counts.
