Kinosternon sonoriense

Body length: 3 1/8 - 6 1/2"
Diet: Insects, crustaceans, snails, fish, and frogs

This aquatic turtle is the true desert survivor. Small and secretive, it lives in most desert areas where water occurs throughout the year, and is very tolerant of poor water quality in drying pools.

Mud turtles probably do not currently occur at Tonto National Monument, but there have been intriguing findings of their shells in recent years, including a fresh shell found in 1996 in the Visitor center parking lot. This shell was possibly carried up from Roosevelt Lake by a bird, but much older shells found in the cliff dwellings were probably brought there by humans. Some shell fragments are burned, suggesting the Salado ate their contents; however, turtle shells were also made into rattles and jewelry.
