Amphiuma is a genus of aquatic salamanders, the only extant genus within the family Amphiumidae /æmfᵻˈjuːmᵻdiː/. They are also known to fishermen as "conger eels" or "Congo snakes", which are zoologically incorrect designations, what with amphiumas being salamanders, and not reptiles, nor fish. Amphiuma exhibits one of the largest compliments of DNA in the living world, around 25 times more than a human.
