Long treated as one species. The Mississippi Mud Turtle lives west of the Mississippi lowlands (Oklahoma, Arkansas, Louisiana, eastern Texas) and down the Mississippi valley; the Eastern Mud Turtle east of it, meeting in Mississippi, Louisiana and Tennessee. A: Two narrow yellow lines along each side, one above and one below the eye in the Mississippi Mud Turtle; mottled or speckled, without two bold lines in the Eastern Mud Turtle. Both have the same big lower shell with two hinges; where both live, the head lines and the place decide.
