The Reef Triggerfish also known by its Hawaiian name Humuhumunukunukuāpuaʻa is the state fish of Hawaii. It is one of several species of triggerfish found at reefs in the Indo-Pacific.

This Hawaiian fish with a long name is pronounced“who moo who moo new coo new coo ah poo ah ah”...or just shortened to "humuhumu".

The name means “trigger fish with a snout like a pig.“

The triggerfish's teeth and top lip are blue and the teeth are set close together inside its relatively plump mouth.

It has a small second dorsal spine which is used to lock its main spine into an upright position. When sheltering in a small crevice, this locking of its spine helps protect the fish against extraction by predators. When fleeing from predators, it sometimes makes grunting noises, possibly to warn other nearby triggerfish.

The triggerfish can blow jets of water from its mouth to help it find food hidden under the sand. It can often be seen spitting sand from its mouth to sift through the material for edible items.

It was chosen as Hawaii’s state fish in 1984 by a public survey. When the humuhumu was first selected as the state fish, lawmakers only made this designation official for five years. So, for a period of over a decade, the Humuhumunukunukuapuaa lost its reign as the state fish, but in 2006 the fish regained it's official state title.

It is not unique to Hawaii, but it is endemic to the waters around the central and south Pacific islands.

It is not a fish people commonly eat.
