Description

The planehead filefish is a small, strongly compressed reef fish of the family Monacanthidae reaching nearly 37 cm. Its skin feels rough and the body carries a large, erectile first dorsal spine that can be locked upright like a trigger. The colour is brown with a marbled pattern that helps it hide among drifting Sargassum weed. The species occurs in the western and eastern Atlantic and the Mediterranean, living on sand and mud bottoms to 293 m and feeding on benthic invertebrates. It is rarely eaten and has been linked to ciguatera poisoning when consumed.
