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.

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.

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 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 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.
