Geographic range

edit

S. triporcatus is found in Belize, northeastern Guatemala, western Honduras, and Mexico. In Mexico it is found in the Mexican states of Campeche, Chiapas, Oaxaca, Quintana Roo, Tabasco, Tamaulipas, and Veracruz.[3]

Description

edit

S. triporcatus is typically much larger than other species of Kinosternidae, attaining a straight carapace length of up to 36 cm (14 in), with males being significantly smaller than females. It is typically brown, black, or green in color, with a yellow underside. The carapace is distinguished by three distinct ridges, or keels, which run the length.[citation needed]

S. triporcatus exhibits XX/XY sex determination, in contrast to the temperature-dependent sex determination of most turtles.[4]

Diet

edit

Like other musk turtle species, S. triporcatus is carnivorous, eating various types of aquatic invertebrates, as well as fish and carrion.[citation needed].
