Graham's Crayfish Snake

Family: 
Colubridae (nonvenomous snakes) in the order Squamata (lizards and snakes)
Description: 

This semi-aquatic snake is fairly nondescript. They are brown to yellow-brown with yellowish-tan stripes along the side of the body. Like most other snakes associated with water, Graham's crayfish snakes are often misidentified as western cottonmouths and needlessly killed.

Size: 
Length ranges from 18 to 28 inches (46-71 cm).
Habitat and conservation: 
This reclusive snake often takes shelter under rocks, logs, or in crayfish burrows along the edge of streams, marshes, sloughs or ponds.
Foods: 
It is named for feeding mainly on freshly molted crayfish and overwintering in crayfish burrows.
Distribution in Missouri: 
Statewide, except for the Ozarks.
