Description

The fringed filefish is a deep, strongly compressed fish of the family Monacanthidae (filefishes) reaching about 20 cm. The skin feels rough like a file, hence the name, and the colour is brown to greenish and marbled, camouflaging it superbly among seagrass and weed. On the head stands a stout, erect dorsal spine that it can lock upright, and under the belly is a fold of skin it can fan out to look larger. The species lives among seagrass, weed and reefs of shallow coastal water along the western Atlantic coast. As an omnivore it eats algae, seagrass, small crustaceans and growth. Because of its camouflage and slow swimming it draws little notice.
