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] DescriptionAdults are {{convert|6|to|8.5|in|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] EcologyThis 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] References1. ^1 2 IUCN SSC Amphibian Specialist Group. 2014.
