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.

As with other crabs, the body is roughly square, with the reduced abdomen tucked beneath the thorax. The thorax bears five pairs of legs, the first of which is armed with large claws. The life span of P. fluviatile is typically 10–12 years. [7] Moulting does not occur in winter. [8]
The fiddler crabs' carapaces are broadened at the front, while the carapaces of ghost crabs are more or less box-like. Lastly, the eyes of ghost crabs have large and elongated eyestalks, with the corneas occupying the entire lower part, while in fiddler crabs the eyestalks are long and thin, with the corneas small and located at the tip.

In the winter, a female crab will bury herself in the sand and become inactive in order to protect her eggs. [3] Eggs typically hatch in the spring, although exact time varies with location. [3] [9] Young crabs are free-swimming after hatching and are diel vertical migrators that can be found at depths up to 80 ft (24 m) during the day. [9]
Sea turtles are not able to regulate body temperature, so a sudden cold snap can turn fatal if the animals become lethargic and experience decreased circulation, causing other body functions slow ...
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. [30]
They also have a similar internal anatomy to freshwater turtles except for the fact that they lack a degenerative cloacal bursae because they do not need to hibernate in water. [ 3 ] Most adults have about a 125–130 mm carapace length, in where the females were significantly longer than males.
According to Price, that could be a south-facing slope in Kentucky’s Red River Gorge, for example. The foundations of old homes can also be attractive places for a snake looking to pass the winter.
