The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
Sea snakes, crocodiles and marine iguanas only dive in inshore waters and seldom dive deeper than 10 m, but both of these groups can make much deeper and longer dives. Emperor penguins regularly dive to depths of 400 to 500 m for 4 to 5 minutes, often dive for 8 to 12 minutes and have a maximum endurance of about 22 minutes.
