There is evidence that marine mammals practice unihemisphericsleep: sleep that occurs in only one brain hemisphere at atime, so that while one hemisphere sleeps, the other is awake.Such sleep is essentially unheard of in terrestrial mammals(although common in birds). What might be the advantages ofunihemispheric sleep for a marine mammal?

Sleep Physiology

Sleep is a condition of reduced muscle movement in the body. Awareness about the surroundings is reduced at the time of sleep. The body stays mildly responsive or non-responsive to external stimuli. The sleep-wake cycle is controlled by the circadian rhythm that produces a resting phase for the body.
