The Sonora mud turtle (Kinosternon sonoriense) is a species of turtle in the Kinosternidae family. It is found in Mexico and the United States. Also known as the Sonoyta Mud Turtle
A small (shell up to 175 mm or 7" in length ) turtle with an olive or gray-brown, dome-shaped shell. The top part of the shell (carapace) has three mild lengthwise keels. The underside of the shell (plastron) is usually yellow-brown and has two hinges so that the front and back can close when the turtle retreats inside. There are small, fleshy projections on the throat. The head and neck are marked with yellow or cream colored reticulations on a dark olive background. The feet are webbed. The markings on the head and neck distinguish this turtle from our other mud turtles.[1]
This species is listed as Near Threatened by the IUCN Red List, but this species is relatively common and seems to need no conservation at the moment.
