description Small-mouthed Salamander Overview

The Small-mouthed Salamander (Ambystoma texanum) is a species of mole salamander native to the central and midwestern United States, with a range extending from the Great Lakes region to the Gulf Coast states. It typically inhabits floodplain forests, marshes, and prairie wetlands, breeding in temporary or ephemeral pools during late winter and early spring. The species is notable for its role in forming all-female, polyploid hybrid lineages known as ambystomatid unisexuals, which reproduce through kleptogenesis—a process in which they acquire sperm from related Ambystoma species to initiate egg development.
