diving

Diving in animal behavior refers to the act of submerging underwater, often for feeding or to escape predators. Different animals have evolved specialized methods for diving. For instance, pelecaniform birds like boobies and gannets plunge from the air to catch prey underwater, relying on the dive's momentum rather than swimming ability. Frigate birds may steal prey from other birds or snatch fish from the surface. Pelicans scoop up fish with their pouches while swimming, sometimes cooperating to herd fish. Cormorants and anhingas are adapted for underwater swimming, pursuing fish or ambushing them.

Mammals like whales exhibit remarkable breath-holding capabilities. Sperm whales can dive for about an hour, reaching depths of over 1,000 meters to hunt giant squid. Blue whales typically dive for 10-20 minutes, but can stay submerged for up to half an hour. Beaked whales are also deep divers, with some species holding their breath for close to an hour. The longest recorded breath-hold is by a Cuvier's beaked whale, lasting over three hours.123
