Two-toed amphiuma

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'. Two-toed amphiumas are some of the largest extant amphibians in the world. Two-toed amphiumas can grow from 39 to 1,042 g (1.4 to 36.8 oz) in mass and from 34.8 to 116 cm (13.7 to 45.7 in) in length. They have four vestigial legs that end in two toes; the number of toes is one of the primary differences between Amphiuma means and its relatives, the one-toed and three-toed amphiumas. The head is pointed and wedge-shaped, and the eyes are small. Adults retain a single gill slit on each side of the head. They are black, dark grey or dark brown in color.
