Amphiuma is a genus of aquatic salamanders that have very small limbs and are sometimes misidentified as snakes or eels. Indeed, members of the genus, which may grow up to three feet long, are often better known by the name Congo eel or Congo snake. These salamanders spend most of their time burrowing through mud and debris searching for insects, mollusks, frogs, and other small prey, but they can also be dangerous to larger animals. Their teeth are quite sharp, their jaws are strong, and their bite can be brutal. Thus, anyone that comes into contact them should be wary.
