Field Guide

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 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 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.

Dekay's brownsnake is a small, secretive species that prefers moist environments. It can be gray to brown to reddish brown. It usually has a tan stripe running down the back, bordered by two rows of small brown spots. The top of the head is usually dark. Occurs statewide.

The broad-banded watersnake is a semiaquatic snake with broad, irregularly shaped bands that can be brown, reddish brown, or black and are separated by yellow or gray. This nonvenomous species is restricted to the southeastern corner of the state.

The northern diamond-backed watersnake is our largest watersnake. It has numerous diamond-shaped light markings along the back. It occurs in the Bootheel and north along the Mississippi River, and in much of northern and western Missouri. It doesn’t occur in the Ozarks or in much of central-eastern 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.

The plain-bellied watersnake is a medium-sized, heavy-bodied, dark-colored, semiaquatic snake with a plain yellow belly. It's present in the Bootheel and north along the Mississippi River floodplain, and along our southernmost counties and northward in western Missouri into parts of northwest Missouri.
