Two-toed amphiuma

The two-toed amphiuma 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 39 to 1,042 g in mass and from 34.8 to 116 cm in length. 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.
