Field Guide

The eastern copperhead is the most common venomous snake in Missouri. Its color varies from grayish brown to pinkish tan, with distinctive hourglass-shaped crossbands.

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 western mudsnake is a harmless swamp dweller of Missouri's Bootheel lowlands. It is burdened with misinformation and imaginative folklore. But it turns out that fact is more interesting than fiction.

The eastern long-tailed salamander and closely related dark-sided salamander are agile and can escape predators by using their tails for quick jumps. They live in the southern and eastern parts of Missouri.

The southern red-backed salamander is small and slender, with a distinct, narrow, red or orange stripe along the back that has saw-toothed edges. It hides under rocks, mosses, and rotten logs in Ozark forests.

The orange-striped ribbonsnake is a type of gartersnake named for the attractive orange or yellow stripes running the length of its body, alternating with wide black stripes. It is found statewide, but seldom far from water.

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.

One of Missouri's most brilliantly colored snakes is also extremely rare to find. The northern scarletsnake is similar in pattern and color to the more common red milksnake but has a red or orange snout and a spotless, white belly.

The harmless eastern milksnake is white, yellow, or light tan, with red or orange blotches bordered with black. The belly is white and strongly checked with black. This species often is misidentified as the venomous coralsnake, which is not found in Missouri.
