Animal Sleep Characteristics and Behaviors

The video explores the diverse sleep patterns of animals, highlighting how different species, including mammals, sea animals, birds, reptiles, and fish, have adapted their sleep behaviors to their environments. Mammals experience REM and non-REM sleep, with some hibernating to conserve energy. Sea animals like dolphins sleep unihemispherically, allowing one brain hemisphere to rest while the other remains alert. Birds and some reptiles also exhibit this behavior. Fish, on the other hand, rest rather than sleep, often seeking protection from predators. Overall, animal sleep is complex and varies widely across species.
