Field Guide

The southern coal skink is secretive. It lives in the southern half of Missouri, excluding the Bootheel. Adults are small, shiny, and brownish, with a wide, coal-black line on the side. Juveniles are black with faint lines down the back and sides and a blue-gray tail.

The western ratsnake, a glossy black snake, is one of Missouri’s largest and most familiar snakes. Its size and dark color make it seem imposing, but it is as harmless to humans as it is bad news for rodents.

The lined snake looks similar to a gartersnake. It is brown to grayish brown, with three lighter-colored stripes down the length of its body and a double row of half-moon-shaped markings along the belly. It occurs mainly in the northwestern part of the state, along the northern border, with a separate population in the St. Louis area.

The western slimy salamander is a black to blue-black salamander irregularly marked with silvery flecks. It occurs in the Ozark Highlands and the Lincoln Hills north of the Missouri River. True to its name, it secretes a thick substance that sticks to skin like glue.

The cave salamander is a common amphibian of the Ozark Plateau. It lives in caves, springs, and rocky streams. Recognize it by its normally bright orange skin dotted with dark brown or black spots.

The prairie kingsnake is fairly common over most of the state. The overall color is tan, brownish gray, or greenish gray. Numerous dark blotches down the back and sides are brown, reddish, or greenish brown. It lives in prairies, open woods, and rocky, wooded hillsides, statewide.

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.

The Great Plains ratsnake is seldom seen. It has numerous brown blotches along the body, a brown eye stripe, and a spearhead marking on top of the head.

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.

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.
