The two-toed amphiuma (''Amphiuma means'') is a snake-like salamander found chiefly in the southeastern United States. It is commonly, but incorrectly, called "congo snake", "conger eel" or the "blind eel". One of the largest extant species of amphibians in the world, they can grow from in mass and from in length.〔(Caudata Culture Species Entry – Amphiuma ). Caudata.org. Retrieved on 2013-01-03.〕〔Deyle, Anna C. (2011) (Population Genetics of ''Amphiuma means'' and ''Siren lacertina'' in Central Florida ). M.S. Thesis, University of South Florida〕 They have four vestigial legs that end in two or three toes which are virtually useless, and eyes with lids. they are blue-black in color. They feed on small fish, crawfish, insect larvae, and even small snakes; they are harmless to humans when left alone, but when disturbed, they can deliver a tough bite, which may lead to a severe infection. Unlike other salamanders, which are mute, ''A. means'' gives a clear whistle when disturbed. == Behavior == Two-toed amphiumas are nocturnal, and are often difficult to handle because of their slippery skins. They may leave water temporarily if weather is wet enough and they dig burrows in muddy bottoms, or may invade the burrows of other aquatic creatures. Amphiumas breed from June to July in North Carolina and northern Florida. Females lay about 200 eggs in a damp cavity beneath debris, and they remain coiled around them during incubation (which lasts around five months). Hatchlings are about long with light-colored gills soon lost after hatching.
