Reptiles and Amphibians
The eastern collared lizard is colorful and has a long tail. If surprised in an open area with no rock crevices nearby to dart into, it often runs on its hind limbs with the forward part of the body held upright.
The six-lined racerunner is a fast, alert ground dweller that don’t usually climb trees. Also called field-streaks and sand lappers, racerunners are close kin to the whiptail lizards you might know from the western United States.
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.
