How whales sleep ? Relaxation animation movie - relaxing music, GURUDE-whales’ lullaby

Whales are the largest existing animals on the planet today. In addition, whales have a unique ability to grit - they have spectral sounds that they use to communicate and hunt in the ocean. They also have a complex social structure and display incredible migratory abilities. Whales sleep by swimming on the surface of the water or by diving to shallow depths to allow access to air. While sleeping, they close one eye to stay alert so they can breathe in time.
