Description

The black triggerfish is a triggerfish of the family Balistidae from tropical seas worldwide. The species grows to about 50 cm and has a dark, nearly black body that shines blue-green in the right light, with pale lines along the base of the dorsal and anal fins. It inhabits clear seaward reefs, especially around oceanic islands, and often gathers in loose groups in the water column. As an omnivore it feeds on zooplankton, algae and small invertebrates. Triggerfishes can lock the first dorsal spine upright to wedge themselves in crevices. The species is harmless to humans.
