The American Heritage Dictionary of the English Language: Fourth Edition. 2000 ] ] ), is one of several species of triggerfish. Classified as "Rhinecanthus rectangulus", it is endemic to the salt water coasts of various central and south Pacific Ocean islands. It is often asserted that the Hawaiian name is one of the longest words in the Hawaiian Language and that "the name is longer than the fish."

Description

The triggerfish's teeth are blue and are set close together inside its relatively chubby mouth, it has a small second spine, which it can use to lock its main spine into an upright position. The triggerfish can wedge itself into small crevices and lock its spine to make it extremely difficult to get out. In addition, when fleeing from predators, the triggerfish will sometimes make grunting noises, possibly a call to warn other nearby triggerfish of danger at hand.

One particularly interesting aspect of the fish's behavior is the ability to blow jets of water from its mouth. These jets help the fish find benthic invertebrates that may be buried under the substrate. Triggerfish can often be seen spitting sand from their mouths in order to sift through the material in search of edible detritus or organisms. Reef triggers are fairly aggressive and will generally not tolerate conspecific species in its general vicinity, thus the fish is often found solitary. This is particularly true in captivity. Triggers have the remarkable ability to rapidly alter their coloration. They can fade into a relatively drab appearance when sleeping or demonstrating submission while the coloration is often the most vivid when the fish is healthy and unthreatened by its surroundings.

Distribution

The reef triggerfish is distributed throughout the Indo-Pacific region, and it is especially prominent in the coral reefs of the Hawaiian Islands.

Hawaii state fish

Due to an expiration of a Hawaiian state law, the trigger fish ceased to be the state fish of Hawaii in 1990. [ [http://www.usatoday.com/news/nation/2006-01-28-humu_x.htm USATODAY.com - Lawmaker seeks official status for humuhumunukunukuapuaa ] ] On April 17, 2006, bill HB1982 was presented to the Governor of Hawaiunicode|i which permanently reinstated the reef triggerfish (humuhumunukunukuapuaunicode|a) as the state fish of Hawaiunicode|i. [ [http://www.capitol.hawaii.gov/session2006/status/HB1982.asp HB1982 Measure History ] ] The bill passed into law on May 2, 2006 and was effective upon its approval.

"Humuhumunukunukuapuaunicode|a" means "triggerfish with a pig-like short snout". It is not, as often claimed, the longest fish name in Hawaiian; that distinction belongs to "lauwiliwilinukunukuunicode|oiunicode|oi" ("long-snouted fish shaped like a "wiliwili" leaf"), the butterflyfish "Forcipiger longirostris". For the purposes of religious sacrifices, every land animal in the Hawaiian islands had an equivalent in the sea.fact|date=September 2007 The Humuhumunukunukuapua‘a was seen as equal to a pig.
