Like every mammal, dolphins need to sleep. Since they have a breathing spout for water when dolphins sleep it can be dangerous because the can get to much water in them so a lot of times when dolphins are sleeping youll see them come up a lot every now and then. Also its dangerous for whale to sleep too but not as dangerous as dolphins because whales can stay underwater much longer than dolphins.

Do humpback whales sleep?
Yes, whales and dolphins do sleep; however, they do not sleep in the same way that humans do. For example, while human sleep involves a period of unconsciousness followed by a period of conscious dreaming or REM sleep, cetaceans (whales and dolphins) show a pattern of unihemispheric slow-wave sleep, meaning that they only sleep with one half of their brain at a time. This allows them to remain aware of their surroundings and continue to surface for air, even while sleeping.
When do whales sleep?
Whales and other water-dwelling mammals such as dolphins are concious breathers. This means they must make a concious effort to swim to the surface to get air. This is opposite to humans, as the brain controls breathing. Whales and dolphins instead let half of the brain sleep at one time, so the animal is never completely unconscious, but it still gets rest periods.
Which are better dolphins or whales?
