Despite its standard name, the Hawaiian Triggerfish has a tropical Indo-Pacific distribution.
The species can be recognised by its distinctive colouration. It is largely whitish with a dark region midlaterally. There are four white-blue stripes descending from the side of the body to that anal fin. Four blue lines cross between the eyes and there are three blue lines between the eyes and the pectoral fin bases. A yellow line enclosing a blue 'moustache' runs between the mouth and the pectoral fin base.
Coral reefs, often in lagoon areas. In more temperate waters, the species occurs on rocky reefs.
The Hawaiian Triggerfish occurs throughout the Indo-Pacific region. In Australia it is known from the central coast of Western Australia to the offshore islands of north-western Western Australia. It also occurs from the northern Great Barrier Reef south to Sydney, New South Wales.
