  • Summary Though very little is known about sleep in wild cetaceans, toothed cetaceans in captivity sleep with one side of their brain at a time [1]. Such uni-hemispheric sleep is thought to enable swimming, voluntary breathing, predator avoidance and/or social contact during sleep at sea [2,3]. Using suction cup tags, we discovered that sperm whales ( Physeter macrocephalus ) worldwide conduct passive shallow ‘drift-dives' in stereotypical vertical postures just below the sea surface.
