Video by @bertiegregory | A pod of spinner dolphins rests in the shallow waters of Sataya Reef, in the Red Sea. These dolphins use the "flat" water created by the reef to rest and play during the day. Sleeping involves shutting down half the brain at a time. This allows them to breathe and look out for predators during naps. At night they head out to hunt in the open ocean, when their prey is nearer the surface.
