Rough-footed mud turtle

The rough-footed mud turtle (Kinosternon hirtipes) is a species of mud turtle in the family Kinosternidae. The species is endemic to the southwestern United States and northern Mexico.

Geographic range
K. hirtipes is found in the United States in Texas, and it is also found in Mexico in the Mexican states: Aguascalientes, Chihuahua, Coahuila, Mexico DF, Durango, Guanajuato, Jalisco, Mexico State, Michoacán, Morelos, and Zacatecas.

Diet
As omnivores, the diet of K. hirtipes primarily consists of vegetation and insects including filamentous algae, seeds and fruits, aquatic, terrestrial, flying arthropods, as well as aquatic gastropods. K. hirtipes undergoes a dietary shift from insects to vegetation as body size increases which facilitates rapid growth. Although male K. hirtipes are larger in size than females, both sexes share a dietary overlap consuming similar foods.

Predation
Based on tracks around kill sites, bite marks and shell damage it has been determined that the main predators of the K. hirtipes are racoons and feral pigs. Not surprisingly, both racoons and pigs are known to hunt several other species of turtle. These turtles seem to be relatively "immune" to predation but are at the highest risk when coming out of the water to nest.

Subspecies
Five subspecies of Kinosternon hirtipes are recognized as being valid, including the nominotypical subspecies.
 * Valley of Mexico mud turtle – Kinosternon hirtipes hirtipes (Wagler, 1830)
 * Lake Chapala mud turtle – Kinosternon hirtipes chapalaense Iverson, 1981
 * San Juanico mud turtle – Kinosternon hirtipes magdalense Iverson, 1981
 * Viesca mud turtle – Kinosternon hirtipes megacephalum Iverson, 1981 (Extinct)
 * Mexican Plateau mud turtle – Kinosternon hirtipes murrayi Glass & Hartweg, 1951
 * Patzcuarco mud turtle – Kinosternon hirtipes tarascense Iverson, 1981

Etymology
The subspecific name, murrayi, is in honor of American zoologist Leo Tildon Murray (1902–1958).
