When sleeping, dolphins often rest motionless at the surface of the water, breathing regularly or they may swim very slowly and steadily, close to the surface. In shallow water, dolphins sometimes sleep on the seabed rising regularly to the surface to breath.

Dolphins sleep by resting half of their brain at a time. This is called unihemispheric sleep. The brain waves of captive dolphins that are sleeping show that one side of the dolphin's brain is "awake" while the other is in a deep sleep, called slow-wave sleep. Also, during this time, the eye opposite the sleeping half of the brain is open while the other eye is closed.

When marine mammals like dolphins simultaneously sleep and swim, they are in a state that is similar to napping. Young dolphin calves actually eat, rest and sleep while their mother swims, towing them along in her slipstream. This placement is technically called echelon swimming. During these times, the mother dolphin will also sleep on the move with her calves.

Dolphins need about eight hours of sleep a day, but, unlike us, their brain sleeps in shifts. The right half gets four hours of sleep and the left half also gets four hours of sleep, just at different times. The awake half of of a dolphin's brain not only helps keeps the dolphin breathing.

Yes, dolphins do sleep when they are tired or need to rest, but not in the same way that humans or other land mammals sleep. Unfortunately dolphins do not have the same luxury as other animals when it comes to getting a good nights rest. In order to the answer question of whether or not dolphins sleep and how they rest we first need to examine the factors that affect a dolphin’s ability to ...

Dolphins have "solved" that by letting one half of their brain sleep at a time. Dolphins sleep about 8 hours a day in this fashion. REM (Rapid Eye Movement) sleep, usually associated with dreaming has been recorded only very rarely. Some scientists claim dolphins do not have REM sleep at all. A dolphin's behaviour when sleeping/resting depends on the circumstances and possibly on individual preferences.

Young dolphins or calves eat and sleep while their mothers " carry " them directly behind in their slipstream, also known as the wake, which moves the calf at the same speed as the mother, requiring less energy from the calf.
