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 African slaves.
The genus Pseudemys comprises approximately seven species, although the validity of some taxa remains in question. Members of this genus are among the largest of the Emydidae, with carapace lengths reaching 17.3 in (44 cm) and weighing up to 22 lbs (10 kg). All are aquatic, spending the majority of their time in lakes, rivers, and ponds where they can easily be seen basking on rocks and logs in sunny weather.
