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.
It is exhibited strongly in aquatic mammals (seals, [17] otters, dolphins, muskrats), [18] but exists in other mammals, including humans. Diving birds, such as penguins, have a similar diving reflex. [6] The diving reflex is triggered specifically by chilling the face and breath-hold.
Diving reflex in a human baby. The diving reflex, also known as the diving response and mammalian diving reflex, is a set of physiological responses to immersion that overrides the basic homeostatic reflexes, and is found in all air-breathing vertebrates studied to date.
Randall William Davis (born 10 May 1952) is an American educator [1] and researcher who studies the physiology and behavioral ecology of marine mammals and other aquatic vertebrates. His physiological research focuses on adaptations of marine mammals for deep, prolonged diving. [2]
The science of underwater diving includes those concepts which are useful for understanding the underwater environment in which diving takes place, and its influence on the diver. It includes aspects of physics, physiology and oceanography. The practice of scientific work while diving is known as Scientific diving.
It is exhibited strongly in aquatic mammals (seals, [7] otters, dolphins and muskrats), [8] and also exists in other mammals, including humans. Diving birds, such as penguins, have a similar diving reflex. [5] The diving reflex is triggered by chilling the face and holding the breath.

Cetacea (/ s ɪ ˈ t eɪ ʃ ə /; from Latin cetus 'whale', from Ancient Greek κῆτος () 'huge fish, sea monster') [3] is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises.
