Field Guide

Graham's crawfish snake is a medium-sized, dull-colored, semiaquatic snake known from prairie streams, marshes, and ponds. Like most other snakes associated with water, it is often misidentified as a cottonmouth and needlessly killed.

The Mississippi green watersnake is a medium-sized, heavy-bodied, dark-colored semiaquatic snake that was once somewhat common in southeastern Missouri. It probably no longer occurs in our state at all.

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.

Mudpuppies are aquatic salamanders that have plumelike external gills throughout their entire lives. They’re found in the southern half and along the eastern edge of Missouri.

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 eastern river cooter is a broad-shelled aquatic turtle with a seemingly small head. It is most abundant in the rivers and sloughs of southern Missouri but also occurs in some of our large reservoirs.

The eastern spiny softshell is a medium to large softshell turtle with small bumps or spines on the front edge of the upper shell. There are dark spots on the fore- and hind limbs.

The midland smooth softshell is a rather plain-looking softshell turtle, with a smooth, rather featureless olive-gray or brown shell, and a light stripe bordered by black extending backward from each eye.

The northern map turtle is a medium-sized aquatic species with a low ridge along the center of the upper shell. A small yellow spot is present behind each eye. It occurs mainly in the Ozarks and the upper Mississippi River in northeastern Missouri.

The Ouachita map turtle is a medium-sized aquatic species with a prominent ridge down the center of the upper shell and bright yellow lines on the head and limbs. A large yellow marking behind each eye extends, narrowing, on top of the head. It occurs in southern and eastern Missouri.
