Field Guide

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.

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 smooth greensnake has been declared extirpated from Missouri. If it is ever found again within our borders, it will probably be as small, relict populations in grasslands in the extreme northern counties. It differs from the similar rough greensnake by having smooth scales, a preference for grassland habitats, and a more northern distribution in Missouri.

The western painted turtle is a small, brightly colored aquatic turtle. The upper shell is smooth and has a red-orange outer edge. The colorful lower shell has a prominent pattern of brown markings. It is found nearly everywhere in the state except the southeast region.

The American bullfrog is Missouri’s largest frog. This common species is easy to hear on warm nights when the males call a deep, sonorous “jug-a-rum, jug-a-rum” that can be heard from half a mile away.

The eastern gartersnake and red-sided gartersnake are Missouri's most common gartersnakes. The color is variable, but there are normally three yellowish stripes, one down the back and one on each side. There are narrow black bars between the scales along the upper lip.

A medium-sized, striped snake of wet prairies and marshes, the plains gartersnake occurs mainly in Missouri's north-central and northwestern counties, with isolated populations in and west of the St. Louis area.
