Field Guide

The western lesser siren is an eel-like, aquatic salamander with external gills, small eyes, small forelimbs with four toes, and no hind limbs. In Missouri, it’s found mostly in the Bootheel and northward in counties near the Mississippi River.

The northern rough greensnake is a long, slender snake common in the Ozarks. It is light green above with a white or yellowish belly. The scales on the back have small ridges that feel rough to the touch. Its beautiful green color helps this mild-mannered insectivore blend in with tree leaves.

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 hellbender is a large, entirely aquatic salamander with a wide, flat head, small, lidless eyes, and soft folds of skin on the sides. In Missouri, it occurs in the northern Ozark highlands in spring-fed rivers that drain north into the Missouri and Meramec river drainages.

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.
