Humuhumunukunukuapua'a
Imagine yourself snorkeling in the clear blue waters of Hawaii. The sun shines down, revealing
a magical underwater world. Suddenly, a colorful fish with bold stripes and a pig-like snout
darts past. You’ve just met the humuhumunukunukuāpua'a, the ocial Hawaii State Fish. This
fearless little warrior is not only a marvel of nature but also a legend in Hawaiian culture. But
why does it have such a long name? What makes it so special? Let’s dive deep into the world
of this unique fish.
The Hawaii State Fish
The humuhumunukunukuāpua'a (Rhinecanthus rectangulus), also known as the reef
triggerfish, was ocially recognized as the Hawaii State Fish in 1985. This title was rearmed
in 2006 due to its deep connection to Hawaiian traditions and its striking appearance in local
waters. The name means “triggerfish with a pig-like snout” in Hawaiian, a fitting description
for this fascinating creature.
A Bold and Colorful Appearance
This small but mighty fish is known for its vibrant colors and patterns. Its body displays a mix
of black, yellow, and gray, with a dark band running across its eyes and a bold stripe on its
cheek. One of its most distinct features is its blue-tinted lips, often described as a “blue
mustache.” These stunning colors help it blend into the reef while also making it one of the
most recognizable fish in Hawaiian waters.

The Habitat of the Hawaii State Fish
The reef triggerfish thrives in the warm, shallow waters of Hawaii’s coral reefs, lagoons, and
coastal areas. It prefers rocky crevices where it can hide and protect itself from predators.
Found throughout the Indo-Pacific region, including Hawaii, this species plays a key role in
maintaining the balance of the reef ecosystem by feeding on algae and invertebrates.
The Unique Behavior of the Humuhumunukunukuapua'a
The Hawaii State Fish is a territorial and aggressive species, especially when it feels
threatened. It has an interesting feeding habit—blowing jets of water to uncover buried prey.
This intelligent hunting technique allows it to feast on algae, small crustaceans, mollusks, and
sea urchins.
Another fascinating defense mechanism is its ability to wedge itself into crevices using a
special dorsal spine. This spine locks in place, making it nearly impossible for predators to
pull the fish out of its hiding spot. When caught or disturbed, the fish makes a grunting sound
similar to a pig, which is how it got part of its name.
The Mystical Connection to Hawaiian Culture
The humuhumunukunukuāpua'a is not just a fish; it is a symbol of Hawaiian folklore and
culture. Ancient Hawaiians believed this fish had mystical powers and saw it as a guardian of
the ocean. Songs, stories, and chants mention this iconic fish, and its importance continues
today. Even visitors to Hawaii often hear the fun and playful Hawaiian song about the
humuhumunukunukuāpua'a, keeping its legend alive.
A Fierce Yet Playful Creature
Despite its small size, the Hawaii State Fish is incredibly bold. It will not hesitate to defend its
territory from intruders, even if they are much larger. During breeding season, males become
even more aggressive, protecting their nests and ensuring the survival of their young. This
fearless nature makes it one of the most interesting fish to observe while snorkeling or diving
in Hawaiian waters.
The Life Cycle of the Hawaii State Fish
Like many reef fish, the humuhumunukunukuāpua'a goes through several life stages. It begins
as an egg, then hatches into a tiny larva. As it grows, it becomes a fry, then a juvenile, and
finally an adult. In captivity, these fish have been known to live up to 20 years, though their
lifespan in the wild remains uncertain. Their body temperature depends on the surrounding
ocean, usually ranging from 77°F to 80°F (25°C to 27°C).
Why This Fish is Special
The Hawaii State Fish is unlike any other. Its ability to change color helps it blend into the
environment or display emotions. It is a master at hiding from predators, using its tough skin
and strong spine as protection. Its grunting noise is a form of communication, especially

A Fish Loved by Many

popular choice for home aquariums. However, keeping one requires careful attention, as they
can be aggressive toward other fish. Aquarium hobbyists admire this species for its beauty
and intelligence, but it thrives best in its natural habitat.
The Role of the Hawaii State Fish in the Ecosystem
This fish plays a crucial role in maintaining a healthy reef. By feeding on algae and sea urchins,
