  2. Aquatic respiration - Wikipedia

    en.wikipedia.org/wiki/Aquatic_respiration

    All aquatic amniotes (reptiles, birds and mammals) have thick and impermeable cutes that preclude cutaneous respiration, and thus rely solely on the lungs to breathe air. When underwater, the animal is essentially holding its breath and has to routinely return to the surface to breathe in new air.

    en.wikipedia.org/wiki/Marine_reptile

    Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment. Only about 100 of the 12,000 extant reptile species and subspecies are classed as marine reptiles, including marine iguanas , sea snakes , sea turtles and saltwater crocodiles .

    A semiaquatic lizard called a diving anole produces a special bubble atop its head to breathe underwater and avoid predators on land, according to research.

  6. Cutaneous respiration - Wikipedia

    en.wikipedia.org/wiki/Cutaneous_respiration

    Some turtles rely on cutaneous respiration from enteral respiration around the cloaca during underwater hibernation. [ 4 ] In some sea snakes , cutaneous respiration can account for up to 30 percent of total oxygen uptake and is important when diving, during which blood is shunted away from the lungs and towards capillaries in the skin, in some ...

  7. Physiology of underwater diving - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_underwater...

    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.

  8. Aquatic animal - Wikipedia

    en.wikipedia.org/wiki/Aquatic_animal

    Aquatic animals generally conduct gas exchange in water by extracting dissolved oxygen via specialised respiratory organs called gills, through the skin or across enteral mucosae, although some are evolved from terrestrial ancestors that re-adapted to aquatic environments (e.g. marine reptiles and marine mammals), in which case they actually ...

  9. Sea turtle - Wikipedia

    en.wikipedia.org/wiki/Sea_turtle

    Sea turtles are air-breathing reptiles that have lungs, so they regularly surface to breathe. Sea turtles spend a majority of their time underwater, so they must be able to hold their breath for long periods. [57] Dive duration largely depends on activity.
