Western Foxsnake
Pantherophis ramspotti
The western foxsnake is a moderately large snake with distinct brown blotches. In Missouri, it is rare and found only in our far northwestern counties.
Eastern Foxsnake
Pantherophis vulpinus
The eastern foxsnake is extremely similar to the western foxsnake and is mainly identified by its different geographic distribution: in Missouri, this rare species is found only in a few counties along the Mississippi River floodplain north from St. Louis.

Kirtland's Snake
Clonophis kirtlandii
Kirtland’s snake is extremely rare and occurs in only a few states in the Midwest. It lives in crayfish burrows in grassland habitats that are damp and near a stream or wetland. It is restricted in Missouri to a few northeastern counties.

Graham's Crawfish Snake
Regina grahamii
Graham's crawfish snake is a medium-sized, dull-colored, semiaquatic snake that occurs throughout Missouri, but not in the Ozarks. Like most other snakes associated with water, it is often misidentified as a cottonmouth and killed out of unwarranted fear.

Smooth Greensnake
Opheodrys vernalis
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.

Orange-Striped Ribbonsnake
Thamnophis proximus proximus
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.
Eastern gartersnake
Eastern Gartersnake and Red-Sided Gartersnake
Thamnophis sirtalis sirtalis (eastern gartersnake) and T. s. parietalis (red-sided gartersnake)
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.

About Reptiles and Amphibians in Missouri

Missouri’s herptiles comprise 43 amphibians and 75 reptiles. Amphibians, including salamanders, toads, and frogs, are vertebrate animals that spend at least part of their life cycle in water. They usually have moist skin, lack scales or claws, and are ectothermal (cold-blooded), so they do not produce their own body heat the way birds and mammals do. Reptiles, including turtles, lizards, and snakes, are also vertebrates, and most are ectothermal, but unlike amphibians, reptiles have dry skin with scales, the ones with legs have claws, and they do not have to live part of their lives in water.
