In the northern part of their range common snapping turtles do not breathe for more than six months because ice covers their hibernating site. These turtles can get oxygen by pushing their head out of the mud and allowing gas exchange to take place through the membranes of their mouth and throat. This is known as extrapulmonary respiration.

Northern map turtles spend the winter under water and do not surface to breathe, especially when ice cover makes this impossible. Adults rest on the bottom or wedged underneath rocks or logs and often hibernate communally with other northern map turtles where they may remain somewhat active throughout the entirety of the winter.

Box turtles in North America are increasingly becoming a conservation concern because of habitat loss and because they are being harvested for the pet trade. [2] The destruction of prairies due to land renovations has led to the decline of the desert box turtles ( Terrapene ornata luteola ) across much of their geographical range.
The single location where Coahuilan box turtles are found is a 360 km 2 region characterized by marshes, permanent presence of water and several types of cacti. Prior to hibernation, box turtles tend to move further into the woods, where they dig a chamber for overwintering. Ornate box turtles dig chambers up to 50 centimeters, while eastern ...
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.
Hibernation takes place during the late autumn season until the spring for softshell turtles. They bury themselves at the bottom of a river/lake in the mud. Food is not as essential as oxygen during this period. Oxygen is needed at a reduced rate than normal and the turtles practice a technique called “pharyngeal breathing”. [17]
Sea turtles: there are seven extant species of sea turtles, which live mostly along the tropical and subtropical coastlines, though some do migrate long distances and have been known to travel as far north as Scandinavia. Sea turtles are largely solitary animals, though some do form large, though often loosely connected groups during nesting ...
Sea turtles will move north during spring and summer seasons to more nutrient rich bodies of water. In fall and winter seasons, they will migrate back in a southward direction. [5] Loggerhead Sea Turtle. Sea turtles are considered ectothermic non-avian reptiles. Temperature has a major effect on both metabolic and physiological process of the ...
