Albula argentea, the silver sharpjaw bonefish, 'ō'io, or simply sharpjaw bonefish, is a species of bonefish found in the tropical Western Pacific Ocean.
The name 'ō'io may refer to other species of bonefish in Hawaii, such as the longjaw bonefish Albula virgata, and the roundjaw/shortjaw bonefish Albula glossodonta.
Taxonomy and nomenclature
Bonefish were once believed to be a single species with a global distribution, but 11 different species have since been identified.
Albula virgata (the longjaw bonefish) and Albula oligolepis (the smallscale bonefish) were formerly assigned to this species, but are now recognized as distinct. A. virgata is only found around the Hawaiian islands, while A. argentea has a wider distribution.
Description
Sharpjaw bonefish grow up to 70cm (28in). Like other bonefish, they have an elongated, silvery white body, with large scales.
