Field Guide

The Ozark zigzag salamander is small and slender, with a narrow, somewhat lobed back stripe that can be yellow, orange, or red. This woodland species lives in Missouri’s southwestern counties along the Arkansas border.

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 marbled salamander is a small, stout salamander with silvery, white, or gray saddle-shaped markings on its body from head to tail. They occur in the southeastern half of the state and are seldom encountered except during the autumn breeding season.

The spotted salamander is one of Missouri's six species of mole salamanders. It is slate black with two irregular rows of rounded yellow spots from the head onto the tail. It occurs in forests in the southern two-thirds of the state.

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.

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.

The prairie massasauga is a medium-sized rattlesnake associated with bottomland prairie habitats in north-central and northwestern Missouri. This endangered species is shy, reclusive, and nonaggressive.

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.

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.

The northern diamond-backed watersnake is our largest watersnake. It has numerous diamond-shaped light markings along the back. It occurs in the Bootheel and north along the Mississippi River, and in much of northern and western Missouri. It doesn’t occur in the Ozarks or in much of central-eastern Missouri.
