Field Guide

The red-eared slider is an attractive aquatic turtle with yellow pinstripes and red ears. It is commonly seen basking on logs or rocks and occurs statewide, except for a few northern counties.

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.

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 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.

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.

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 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.

The green frog looks similar to a bullfrog but is smaller and has a ridge of skin along the sides of the back that is not found on bullfrogs. It is a game animal in Missouri.

The northern watersnake and midland watersnake are Missouri's two subspecies of common watersnake. Together they occur statewide. Color is variable: gray, tan, or reddish brown with dark crossbands or blotches. The belly is cream-colored with red, brown, or black spots or half-moon markings.

Graham's crawfish snake is a medium-sized, dull-colored, semiaquatic snake that occurs throughout Missouri, but not in the Ozarks. Like most other snakes associated with water, it is often misidentified as a cottonmouth and killed out of unwarranted fear.
