The Yellow Longnose Butterflyfish

The Yellow Longnose Butterflyfish (Forcipiger longirostris) is a very common butterflyfish. Along with its relative, the big longnose, they have one of the longest Hawaiian fish names, lau-wiliwili- nukunuku-‘oi-‘oi. Its meaning is “leaf of the wili-wili tree with a sharp nose.” The hue of the fish is similar to the coloring of the big, billowy leaves of the Hawaiian wili-wili tree. The Yellow Longnose Butterflyfish has a disc-like shaped body that is laterally compressed, and it has a long protruding snout tipped with a small mouth. The dorsal fin is continuous, and it has a rounded tail fin. This fish has a bright yellow body as well as yellow dorsal, anal, and pelvic fins. There is a black bar over the nape covering the upper half of the eyes, giving a mask-like appearance.

These Butterflyfish spend most of their time near exposed seaward reefs where there is lots of coral growth, rocky caves, and ledges, and they are also found in lagoon reefs. They inhabit depths from between 3 to 476 feet with environments that include everything from shallow flats to very deep walls. They are usually seen in pairs though sometimes seen in small groups of as many as five individuals, and occasionally they are seen alone.
