Species of Conservation Concern
Scientific Name
Ambystoma talpoideum
Ambystomatidae (mole salamanders) in the order Caudata (salamanders)

A salamander with a large head, small body and tail, and large limbs. There are 10 or 11 costal grooves (vertical grooves on the sides of the body). It is usually dull gray or brown. Most individuals have white or light gray flecks over most of the body, limbs, and tail.

Length: 3–4 inches.
Where To Find
Mole Salamander Distribution Map
Restricted to the Mississippi Lowlands in southeastern Missouri. The overall range extends into Virginia, Florida, and Texas, with isolated populations in some southern states.
Lives in lowland forests, taking shelter under logs, leaf litter, and in the soil. Mole salamanders are associated with marbled and small-mouthed salamanders. They are seldom encountered because they rarely venture above ground, except during breeding season.
Mole salamanders eat a variety of small insects, worms, and land snails.
A Species of Conservation Concern in Missouri. It requires natural swamps and lowland forests to survive. This habitat has been greatly reduced in southeastern Missouri, and the remaining swamps and forests should be protected.
Life Cycle
Breeding occurs in leaf-littered ephemeral or semipermanent pools and woodland ponds. Adults move to breeding ponds and pools in bottomland forests in late autumn or early winter, where breeding likely takes place between December and February. Courtship occurs in the water. A female may produce 200 to over 500 eggs, which are loosely attached to submerged twigs or leaves in small clumps of 4–20 eggs. The larval stage usually lasts 3–4 months, sometimes much longer.
As humans pursue our own needs, such food, territory, shelter, and money, we tend to destroy and fragment natural landscapes. The swamplands of the Bootheel were mostly destroyed for cotton farming. The natural swamps that remain should be carefully protected.
Adults of most salamanders in this family spend most of their time in the soil, often in burrows made by small mammals. Their welfare is therefore linked to the activities of mice, moles, shrews, and other animals.

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.
