The three species of Amphiuma are similar but can be differentiated based on the number of toes (one, two, or three), coloration, and body size.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: United States
U.S. state distribution from AmphibiaWeb's database: Alabama, Florida, Georgia, Mississippi
Life History, Abundance, Activity, and Special Behaviors
Diet consists of mud-dwelling invertebrates, including earthworms, sphaeriid clams, arthropod larvae, and beetles. Possible predators include racoons, feral pigs, mud snakes (Farancia), snapping turtles, and two-toed amphiumas. Although they tend to keep to the thick bottom-layer of muck, one-toed amphiumas must come to the surface to breathe. During dry periods and droughts, one-toed amphiumas will stay in burrows at least 12 inches underground (Means 1992).
