Field Guide

The eastern musk turtle is one of the world’s smallest turtles. It has a dark, domed upper shell and reduced lower shell. It occurs along our Mississippi River counties and in the southern two-thirds of the state.

The western painted turtle is a small, brightly colored aquatic turtle. The upper shell is smooth and has a red-orange outer edge. The colorful lower shell has a prominent pattern of brown markings. It is found nearly everywhere in the state except the southeast region.

Although well equipped for an aquatic existence, the Mississippi mud turtle spends as much time wandering about on land as it does in water. Look for it in the Mississippi Lowlands of Missouri’s Bootheel.

The small-mouthed salamander is a medium-sized, dark gray to black or dark brown salamander with a small head and mouth. In Missouri, it’s found nearly statewide — but not in the Ozarks.

The yellow mud turtle is a small, uniformly colored, semiaquatic turtle restricted to certain counties in west-central, northeastern, and southwestern Missouri. It is an endangered species in our state.

The southern painted turtle is small and has a prominent yellow, orange, or red lengthwise stripe down the middle of the upper shell. In Missouri, this aquatic turtle is found only in the Bootheel region.

A large aquatic turtle with a big pointed head, long thick tail, and small lower shell, the eastern snapping turtle is common throughout the state, anywhere there is permanent water.

In Missouri, alligator snapping turtles are protected, and it is illegal to harvest them. This species is totally aquatic and rarely leaves the water. In Missouri, it mainly occurs in the large rivers, sloughs, and oxbow lakes of our southern, southeastern, and eastern counties.

The southern coal skink is secretive. It lives in the southern half of Missouri, excluding the Bootheel. Adults are small, shiny, and brownish, with a wide, coal-black line on the side. Juveniles are black with faint lines down the back and sides and a blue-gray tail.

The cottonmouth is named for the cotton-white lining of its mouth, which it opens widely when alarmed. This dangerously venomous, semiaquatic snake occurs in the southeastern corner of Missouri, with a spotty distribution in the Ozark Region.
