Description

The rough triggerfish is an open-ocean triggerfish (family Balistidae) occurring worldwide in warm seas. The species grows to about 50 cm and has a deep, laterally compressed, brown-grey body often dotted with pale spots. It lives almost its entire life epipelagically in shallow coastal and offshore waters and often stays near drifting objects; sometimes it occurs over deep rocky slopes. Its diet consists of zooplankton and small invertebrates. Like all triggerfish it can lock the first dorsal spine upright. In some tropical areas the flesh can contain ciguatera.
