Pseudemys is a genus of large, herbivorous, freshwater turtles of the eastern United States and adjacent northeast Mexico. They are often referred to as cooters, which stems from kuta, the word for turtle in the Bambara and Malinké languages, brought to America by enslaved people from Africa.

Pseudemys in the context of Ectotherm
An ectotherm (from Ancient Greek ἐκτός (ektós) 'outside' and θερμός (thermós) 'heat'), more commonly referred to as a "cold-blooded animal", is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. Such organisms (frogs, for example) rely on environmental heat sources, which permit them to operate at very economical metabolic rates.
Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms. In contrast, in places where temperature varies so widely as to limit the physiological activities of other kinds of ectotherms, many species habitually seek out external sources of heat or shelter from heat; for example, many reptiles regulate their body temperature by basking in the sun, or seeking shade when necessary in addition to a host of other behavioral thermoregulation mechanisms.
