Mudpuppies and Waterdogs of the United States
Two genera, Necturus, the mudpuppies and waterdogs, with 5 species in eastern North America, and 1 species of Proteus, a blind cave dweller in Europe. Mudpuppies and waterdogs are aquatic permanent larvae, characterized by deep red plume like gills, 4 toes on both front feet and hind feet, and strongly compressed tails. The male's vent is lined with tiny projectdions, bears 2 fleshy lobes, and is followed by a tranverse broove. Fertilization is internal and the eggs are laid on the undersides of stones or logs on stream bottoms. The female guards the eggs until hatching.
