The midland and southern painted turtles seek especially quiet waters, usually shores and coves. They favor shallows that contain dense vegetation and have an unusual toleration of pollution. [103] [104] The western painted turtle lives in streams and lakes, similar to the other painted turtles, but also inhabits pasture ponds and roadside ...
As air-breathing reptiles, sea turtles must surface to breathe. They spend most of their time underwater, so must be able to hold their breath for long periods to avoid frequent surfacing. Dive duration largely depends on the activity. A foraging sea turtle may typically spend 5–40 minutes under water [108] while a sleeping sea turtle can ...
They can hold their breath for much longer periods than other reptiles and they can tolerate the resulting low oxygen levels. They can moderate the increase in acidity during anaerobic (non-oxygen-based) respiration by chemical buffering and they can lie dormant for months, in aestivation or brumation .
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 ...
The painted wood turtle feeds on fruit, insects, and worms. Their diet should consist of 60% leafy greens, 30% protein, and 20% fruits and vegetables. Along with a varied diet, they require additional calcium to insure healthy shell growth. Unlike aquatic turtles, the painted wood turtle doesn't require water in order to swallow its food.
They can be very beneficial to aquariums because some species can live for more than 30 years and they can help to clear your tank, through the process of natural filtration. 26. Stinkpot Musk Turtles
The southern painted turtle ranges from extreme southern Illinois and Missouri, roughly along the Mississippi River Valley, to the south. In Arkansas, it branches out to the west towards Texas, where it is found in the far northeast part of that state (Caddo Lake region) [13] as well as extreme southeastern Oklahoma (McCurtain County).

Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply.
