Species Types
Scientific Name
Ambystoma opacum
Description
Unlike many of its close relatives, this salamander breeds in the autumn instead of early spring, and on land instead of in water. Females lay their eggs near a pond, curl protectively around them, then wait until rains make the pond water high enough to cover the eggs.

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.
