The Mexican musk turtle (Staurotypus triporcatus), also known commonly as the giant musk turtle, is a species of turtle in the family Kinosternidae. The species occurs in Central America and Mexico.

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].
