Yellow Mud Turtle

The yellow mud turtle is a small, olive-colored turtle. Both the common name, yellow mud turtle, and the specific name, flavescens (Latin: yellow), refer to the yellow-colored areas on the throat, head, and sides of the neck. The bottom shell (plastron) is yellow to brown with two hinges, allowing the turtle to close each end separately. The male's tail has a blunt spine on the end, but the female's tail does not.

Northeastern Mexico: Chihuahua, Coahuila, Nuevo León, and Tamaulipas. Midwestern and Southwestern United States: Arizona, Colorado, Illinois, Iowa, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, and Texas. Its current presence is uncertain in Veracruz (Mexico) and Arkansas (United States).

Yellow mud turtles are omnivorous. Their diet includes worms, crayfish, frogs, snails, fish, fairy shrimp, slugs, leeches, tadpoles, and other aquatic insects and invertebrates. They also eat vegetation and dead and decaying matter. Yellow mud turtles forage on land and water for food. In early spring their main diet is fairy shrimp they find in the shallows of their ponds. While they are burrowing, they will eat earthworms or grubs they encounter. Some studies show these turtles will eat earthworms that pass in front of them while hibernating. They also consume fish and other aquatic organisms.
