8 Strange Animal Sleeping Habits

The video explores the necessity of sleep across various animal species, highlighting unique adaptations that allow them to rest while remaining alert to danger. Large herbivores like giraffes and horses have evolved to sleep standing up, while birds like frigate birds can sleep while flying. Marine mammals such as dolphins use unihemispheric sleep to breathe and rest simultaneously. Sharks employ yo-yo diving to rest while moving, and parrotfish create mucus bubbles for protection during sleep. Octopuses exhibit REM sleep, suggesting a link to their intelligence.
