Description

The redtooth triggerfish is a triggerfish (Balistidae) from the Indo-West Pacific. The species has a blue-green to purplish body, a deeply forked tail with elongated lobes and conspicuous red teeth, to which the name refers. It inhabits reef channels and slopes with strong currents, where it often hovers above the reef in large, loose schools. Unlike many triggerfishes it is a peaceful planktivore: it captures zooplankton from the current. When threatened it dives into a crevice and locks itself in place with its dorsal spine. The species is harmless to humans.
