features

The diamond Picasso triggerfish becomes 30 centimeters long. It has a striking, high-contrast coloration. A large black wedge extends from the anal fin to the eyes and camouflages them. The caudal, anal and dorsal fins are light blue. Like all representatives of the triggerfish, it can fix the first dorsal spine in an upright position using the second spine.

Fin formula : dorsal III / 22–25, anal 0 / 20–22.

Way of life

The diamond Picasso triggerfish live mainly as solitary animals on reef terraces and in the shallow zones of the outer reefs. It eats algae, foraminifera , molluscs , crustaceans , worms, echinoderms , fish and their spawn.

Hawaiian state fish

The fish, which is called Humuhumunukunukuāpua'a in Hawaiian (roughly translated: triggerfish with a mouth like a pig ), is the state fish of the US state of Hawaii .

Fish had already been given this role in 1985, but this regulation expired automatically in 1990, after five years. On April 17, 2006, the Senate approved the submission of Ordinance HB1982, which permanently establishes fish as the state fish. The ordinance came into force on May 2, 2006.
