Hawaiian Squirrelfish

‘ala‘ihi

The Hawaiian squirrelfish, or ‘ala‘ihi in Hawaiian, are easily identified by their unique, vibrant red coloration, large eyes, and silvery-white stripes. The Hawaiian squirrelfish reaches approximately 6.5 inches in length and has a deep red dorsal fin with white spine tips and a unique white line beneath its mouth. Their dark, distinct eyes and unique behavior probably contribute to their popular name, squirrelfish.

Unlikely to be spotted in the daylight, the Hawaiian squirrelfish is a nocturnal species that spends most of the day hiding in ledges and caves, emerging at dusk to feed. Their large eyes and mouth are an adaptation for these nighttime predators; they take advantage of the darkness to feed on crustaceans found on the reef.

Often spotted peering out from holes in the reef, the Hawaiian squirrelfish will quickly flee when approached. The Hawaiian squirrelfish is amongst the most common types of fish in the islands. They are endemic to Hawaiian waters, meaning that they are found nowhere else in the world.
