Do whales sleep under water?
If asked, do whales sleep underwater? 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.
