Menopome

Menopome, either of the two species of Amphibian genus Menopoma, from the Mississippi basin, and having the gill-slits persistent. With the Giant Salamander, they form a family. They are ugly and voracious; and such names as ." mud-devil" and "hell-bender" show the abhorrence in which they are held.
