Eastern Hog-Nosed Snake
Heterodon platirhinos
The eastern hog-nosed snake is a nonvenomous snake that is highly variable in color and pattern. It has an upturned snout and can hiss loudly and spread its neck like a cobra. If this defense fails, the snake may thrash around, open its mouth, roll over, and play dead.

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.

Bullsnake
Pituophis catenifer sayi
Missouri's largest snake, the bullsnake may hiss loudly and vibrate its tail when alarmed, but it is nonvenomous. This species is extremely valuable in controlling destructive rodents.

Timber Rattlesnake
Crotalus horridus
Missouri’s largest venomous snake, the timber rattlesnake, is dangerously venomous, but there are few cases of rattlesnake bites in our state. It frequents rough country, is mostly nocturnal in summer, and few Missourians ever encounter it.

Broad-Banded Watersnake
Nerodia fasciata confluens
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.

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.
Dusty hog-nosed snake curled on a sand prairie
Dusty Hog-Nosed Snake
Heterodon gloydi
In Missouri, the dusty hog-nosed snake is found only in a few southeastern counties. This nonvenomous snake is a species of conservation concern. Like other hog-nosed snakes, it has several interesting defensive behaviors.

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.
