Amphiuma
''Amphiuma'' is a genus of aquatic salamanders, the only extant genus within the family Amphiumidae . They are also known to fishermen as "conger eels" or "Congo snakes", which are zoologically incorrect designations. The Amphiuma has one of the largest amounts of DNA in the living world, around 25 times more than a human.〔("Junk DNA and the Onion Test" ) 1 June 2008.〕
== Description ==
Amphiumas have an elongated body, generally grey-black in color. They do have legs, but they are merely vestigial and very small. While amphiumas can be up to long, their legs measure only up to about . It is because of this that they are often mistaken for eels or snakes. They also lack eyelids and a tongue. Amphiumas also have a lateral line visible on the sides of their bodies, which are capable of detecting movement and are used in aid of hunting.〔()〕
Female amphiumas lay their eggs in wet mud, and then remain coiled around them for about five months, until they hatch. The larvae have external gills, but after about four months these external gills disappear and the lungs begin to work. One pair of gill slits, with fully functioning internal gills, is retained and never disappears, so the metamorphosis remains incomplete.〔
