The red-eared slider is an attractive aquatic turtle with yellow pinstripes and red ears. It is commonly seen basking on logs or rocks and occurs statewide, except for a few northern counties.

The eastern musk turtle is one of the world’s smallest turtles. It has a dark, domed upper shell and reduced lower shell. It occurs along our Mississippi River counties and in the southern two-thirds of the state.

The eastern spiny softshell is a medium to large softshell turtle with small bumps or spines on the front edge of the upper shell. There are dark spots on the fore- and hind limbs.

The cottonmouth is named for the cotton-white lining of its mouth, which it opens widely when alarmed. This dangerously venomous, semiaquatic snake occurs in the southeastern corner of Missouri, with a spotty distribution in the Ozark Region.

The small-mouthed salamander is a medium-sized, dark gray to black or dark brown salamander with a small head and mouth. In Missouri, it’s found nearly statewide — but not in the Ozarks.

The yellow mud turtle is a small, uniformly colored, semiaquatic turtle restricted to certain counties in west-central, northeastern, and southwestern Missouri. It is an endangered species in our state.

The southern painted turtle is small and has a prominent yellow, orange, or red lengthwise stripe down the middle of the upper shell. In Missouri, this aquatic turtle is found only in the Bootheel region.

In Missouri, alligator snapping turtles are protected, and it is illegal to harvest them. This species is totally aquatic and rarely leaves the water. In Missouri, it mainly occurs in the large rivers, sloughs, and oxbow lakes of our southern, southeastern, and eastern counties.

The western lesser siren is an eel-like, aquatic salamander with external gills, small eyes, small forelimbs with four toes, and no hind limbs. In Missouri, it’s found mostly in the Bootheel and northward in counties near the Mississippi River.

A large aquatic turtle with a big pointed head, long thick tail, and small lower shell, the eastern snapping turtle is common throughout the state, anywhere there is permanent water.
