Octopuses in Hawaii
Octopuses are some of the most fascinating animals on Hawaii's reefs. They have eight arms, powerful suction cups, flexible bodies and the ability to change color and texture quickly. Because they have no bones or shell, they can squeeze into small reef holes and rocky crevices.
In Hawaiian, octopus is called he'e. The Hawaiian Day Octopus is known as he'e mauli. This is the octopus snorkelers and divers are most likely to see in Hawaii because it is active during the day.
Camouflage and Intelligence
Octopuses are very good at hiding. A Hawaiian Day Octopus can shift color, change skin texture and flatten against the reef so well that it may look like rock or coral rubble. If threatened, it may also release ink and slip away quickly.
They are also intelligent animals. They can solve problems, inspect objects and use their arms with careful control. Their suction cups help them grip rocks, search holes and hold prey.
Where They Live and Feed
Hawaiian Day Octopuses live around shallow reefs, rocky areas and reef crevices. They hunt crabs, shrimp, small fish and other reef animals, often using their arms to search along rocks and inside holes.
If you see an octopus, watch from a respectful distance. Do not touch, chase or corner it, and never reach into reef holes. Related pages include the Hawaii fish guide, eels, crabs, scorpionfishes and Hawaii snorkeling tours.
