Description
The dotterel filefish is an elongate filefish of the family Monacanthidae (filefishes) reaching about 45 cm. The laterally compressed, grey-brown body with fine spots feels rough like a file due to its minute scales. On the head stands a first dorsal spine that can be locked upright like a trigger. The small mouth bears strong teeth. The species roams open water above the continental shelf on both sides of the Atlantic, often hanging head-down near drifting weed or material, where it camouflages itself. It is an omnivore eating growth, weeds, small invertebrates and drifting material. It has little fishery value.
