Plains Hog-Nosed Snake
Heterodon nasicus
The plains hog-nosed snake has probably been extirpated from Missouri. It has a sharply upturned snout, black pigment on the underside of the tail, and was only known from the loess hill region of extreme northwest Missouri.
Image of a western foxsnake
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.
Image of a bullsnake
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.
Image of a variable groundsnake
Variable Groundsnake
Sonora semiannulata semiannulata
The variable groundsnake is a small species with smooth, shiny scales and highly variable coloration. In Missouri, it is mostly restricted to open, rocky hillsides of the southwestern corner of the state.
Image of a timber rattlesnake
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.

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.
Image of a broad-banded watersnake
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.

Eastern Long-Tailed Salamander and Dark-Sided Salamander
Eurycea longicauda longicauda (eastern dark-sided salamander) and E. l. melanopleura (dark-sided salamander)
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.
Photo of an eastern yellow-bellied racer.
Eastern Yellow-Bellied Racer and Southern Black Racer
Coluber constrictor flaviventris (eastern yellow-bellied racer) and Coluber constrictor priapus (southern black racer)
The eastern yellow-bellied racer is uniformly tan, brown, olive, blue, gray, or nearly black on top, with a yellow, cream, or light blue-gray belly. It occurs nearly statewide. The southern black racer subspecies also lives in the southeastern half of the state.

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.
