An ugly, scaleless fish living in the depths of caverns, the monstrous Red Jaw had its eyes set in the top of its head. Its gaping jaws, like those of the sea shark, contained up to seven rows of sharp teeth (but this characteristic did not endear them to Dwarves...). Aside from the bright red jaw and the luminescent growths of their fins, the Red Jaw was colorless. These fish could provide quite a brilliant display in a darkened stream or lake, as their luminescent red fins flicked to and fro; they could provide quite a display of another sort as they swallowed a dog or goat whole or devoured a Dwarf's leg in seconds.
