, the surgeonfishes, unicornfishes and tangs. This fish is found in the western Pacific Ocean in Indonesia.

Taxonomy

Prionurus chrysurus was first formally

type locality given as “the blue lagoon” at Padang Bai on Bali.[2] The genus Prionurus is the only genus in the tribe Prionurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamiles in the family Acanthuridae.[3]

Etymology

Prionurus chrysurus has a specific name, chrysurus which combines "chrysos", meaning ”gold” , with ouros, which means “tail”, a reference to the yellow caudal fin of this fish.[4]

Prionurus chrysurus is a distinctive species within the genus Prionurus, the

standard length of the Indonesian sawtail is 30 cm (12 in).[6]

Distribution and habitat

Prionurus chrysurus is found in the Western Pacific Ocean where it is known only from Indonesia. It is found from Bali to western Flores and also off Lombok. The species in the genus Prionurus shows an Antitropical distribution in the Pacific preferring cooler waters and the Indonesian sawtail prefers upwellings where the water temperature is 20-23 °C. It has been postulated that it is a glacial relict which had a wider distribution in a period off global cooler temperatures.[1]
