Abstract
Fully aquatic cetaceans can sleep while in motion with only one eye closed at a time. They display a unique form of sleep called unihemispheric slow-wave sleep and show no apparent indications of rapid eye movement (REM). Semiaquatic mammals can sleep both on land and in water and display two different sleep patterns. Sleep in the first group (true seals and walrus) is largely not different from that seen in terrestrial mammals, except for long apneas displayed both on land and in water. Sleep in others (e.g., fur seals) is similar to the sleep of terrestrial mammals while on land and to the sleep of cetaceans while in water.
