From the IUCN Red List Species Account:


Range Description

This species can be found in Lower Coastal Plain from Texas eastward to the Mobile Bay drainage in Alabama, USA (Bart et al. 1997).

Habitat and Ecology

It can be found in spring-fed streams with sandy bottom. It is a bottom dweller. In Louisiana, it is closely associated with leaf-litter deposits in streams, and animals may burrow into the bottom during the warm season (Bart and Holzenthal 1985). It probably attaches eggs to objects in water.


Subpopulations in the core of the range are apparently secure.

Population Trend


Major Threats

It is possibly threatened by stream siltation and pollution, but the importance of this factor is unknown (Petranka 1998).

Conservation Actions

Its range overlaps with several protected areas. More information is needed on its taxonomic status, population status, life history and threats.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution and presumed large population.

Taxonomic Notes

Bart et al. (1997) determined that Necturus alabamensis and N. beyeri are distinct species and that the name N. alabamensis applies only to the waterdog in the upper Black Warrior River drainage (see Bart et al. (1997) for an account of the nomenclatural history of this and related species). Waterdogs included here in the N. beyeri complex evidently comprise multiple species (Guttman et al. 1990; Bart et al. 1997); further study is needed to resolve the taxonomic status of the involved populations.
