Turtles can breath through their butts. No sh…..kidding. Technically it’s called cloacal respiration and it’s not so much breathing as it is defusing oxygen in and expelling carbon dioxide out. Whatever you call it, when a turtle hibernates their main source of oxygen is through their butt. Because they are cold blooded, when their internal temperature drops so does their metabolism and therefore their need for oxygen is greatly reduced. For the most part water running over them is enough to sustain their life until Spring and warmer weather arrives. This breathing process is fairly common amongst amphibians and reptiles and is properly called cutaneous respiration, meaning through the skin rather than by using lungs of gills. Besides the turtle butt-breathers, other users of cutaneous respiration include frogs, salamanders and sea snakes.
