The dwarf waterdog (Necturus punctatus) is the smallest member of the family Proteidae, and is endemic to the United States.

Description[edit]

This species is usually between 4.5 and 7.5 in (11.4–18.9 cm) long, and has bushy, narrow gills and a compressed tail. All feet have four toes. The salamander is dark brown or slate-grey to black above, and has a grey belly with a bluish-white band along the midline. Unlike other members of the Proteidae family, it is without any black spots.

Habitat[edit]

Dwarf waterdogs live in slow-moving, muddy or sandy-bottomed streams and associated deep irrigation ditches.

Geographic range[edit]

Necturus punctatus is found on the coastal plain from southeastern Virginia to southcentral Georgia,[1] and may extend westward along the Gulf Coastal plain.
