One of several sliders/cooters seen, only one photographed and included here.
Three washed ashore dead, no obvious sign of bullet holes or clubbing damage. Drowned or diseased, or what?
Curled up in shell, hopefully close ups of shell helps someone id it better than I can.
Pseudemys is a genus of large, herbivorous, freshwater turtles of the eastern United States. 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.
