Reptiles and Amphibians
Pituophis catenifer sayi
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.
Coluber flagellum flagellum
The eastern coachwhip is a long, slender, nonvenomous snake that usually escapes in an explosive burst of speed. It thrashes when captured, which led to the stubborn myth that this snake can whip a person to death.
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.
