The Gulf Coast waterdog (Necturus beyeri) is a species of aquatic salamander in the family Proteidae. It is native to the southeastern United States, where it occurs in Alabama, Florida, Georgia, Louisiana, Mississippi, and Texas .[1] This may be a species complex that could be split into different taxa as research indicates.[2] It is closely related to Necturus alabamensis.[1]

Description

Adults are 6 to 8.5 inches (15 to 22 cm) in length. It is brown with light brown and black speckles. It exhibits neoteny, retaining its gills and larva-like tail into adulthood.[3]

Ecology

This species lives in streams with sandy bottoms. It remains on the substrate or burrows into it, sometimes hiding in debris.[1]

Individuals of both sexes move more during the colder months of the year and seem to use one site as a home area from which they occasionally exhibit long distance movements.[4]

The female attaches its eggs to aquatic debris.[5]
