Description

They are typically much larger than other species of Kinosternidae, attaining sizes of up to 36 cm (14 in) carapace length, with males being significantly smaller than females. They are typically brown, black, or green in color, with yellow undersides. Their carapaces are distinguished by three distinct ridges, or keels, which run their length.

Diet

Like other musk turtle species, they are carnivorous, eating various types of aquatic invertebrates, as well as fish and carrion.
