I WOULD like to introduce you to what is known as the Hawaiian triggerfish.

Despite its name making you think of tropical islands, dancing girls and cocktails by the water, the Hawaiian triggerfish has a tropical Indo-Pacific distribution.

Triggerfish are widespread in shallow tropical and subtropical waters. You can find them inhabiting shallow coral reefs in depths up to 50m.

You can find them in more temperate waters and the species occurs on sections of rocky reefs.

They can be found from Point Quobba to the Dampier Archipelago and offshore reefs of Western Australia, Ashmore Reef in the Timor Sea, and the northern Great Barrier Reef and reefs in the Coral Sea, to southern Queensland, with juveniles to at least Sydney, New South Wales; also, Cocos (Keeling) Islands in the eastern Indian Ocean, and Lord Howe Island in the Tasman Sea.

Elsewhere the species occurs in the tropical, Indo-west-central Pacific. They Inhabit reef flats and shallow offshore reefs.

The species feeds on algae, detritus and invertebrates. Triggerfish tend to be more carnivorous spending time eating a wide variety of echinoderms and crustaceans like crabs, shrimps, sea urchins, worms, and other invertebrates. …
