Description
Distribution: Atlantic, Indian and Pacific Oceans. Usually compressed body. Pelvic fins fused to one spine. First dorsal spine with locking mechanism. With 12 principal rays in caudal fin. 18 vertebrae. Upper jaw non-protrusible. Upper jaw usually with four teeth in outer and three in the inner series on each premaxillary. Capable of rotating eyeballs independently. Triggerfish normally swim by undulating their second dorsal and anal fins, but will use their tail for rapid bursts. Most triggerfishes are solitary diurnal carnivores, feeding on a wide variety of invertebrates including hard-shelled mollusks and echinoderms; some also feed on algae or zooplankton. They lay demersal eggs in a nest which is aggressively guarded by the female, less often by the male. Popular and hardy in aquaria, but often aggressive.
