Menobranchus punctatus Gibbes, 1850
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.
Dwarf waterdogs live in slow-moving, muddy or sandy-bottomed streams and associated deep irrigation ditches.
