small green snake coiled in straw
Species Types
Scientific Name
Opheodrys vernalis
Description
The smooth greensnake has been declared extirpated from Missouri. If it is ever found again within our borders, it will probably be in grassy meadows in the northern half of the state. It differs from the similar rough greensnake by having smooth scales, a smaller size, and a more northern distribution in Missouri.

northern rough greensnake
Species Types
Scientific Name
Opheodrys aestivus aestivus
Description
The northern rough greensnake is a long, slender snake common in the Ozarks. It is light green above with a white or yellowish belly, and the scales on the back have small ridges or keels that feel rough to the touch. Its beautiful green color helps this mild-mannered insectivore blend in with the trees that are its home.

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.
