Cirrhitichthys aureus, the yellow hawkfish, the golden hawkfish or golden curlyfin, is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is native to tropical reefs of the Indian Ocean and the western Pacific Ocean.

Taxonomy[edit]

Cirrhitichthys aureus was first formally described in 1842 as Cirrhites aureus by Coenraad Jacob Temminck and Herman Schlegel with the type locality given as the outer bays of Nagasaki.[1] The specific name aureus means “gold”, a reference to its golden yellow colour.[2]

Description[edit]

Cirrhitichthys aureus has a dorsal fin which contains 10 spines and 12 soft rays,[3] the first soft ray is extended.[4] The anal fin has 3 spines and 6 soft rays.[3] The pelvic fin extends past the anus and the caudal fin is weakly emarginate.[4] This species reaches a maximum total length of 14 cm (5.5 in).[3] The overall colour is yellow to orange with large, indistinct, dusky brown blotches along the back. There is a pair of poorly defined brown spots just above the gill cover. The fins are yellowish in colour with spots on the soft rayed part of the dorsal fin.[3]

Distribution and habitat[edit]

Cirrhitichthys aureus is found in the Indo-Pacific region from India east to Japan and China, it has also been recorded in southern Indonesia.[3] Thus species is found around rocky cliffs within reefs and is found at depths between 5 and 20 m (16 and 66 ft).[5]

Biology[edit]

Cirrhitichthys aureus have been shown, at least in captivity, to be able to change sex in either direction. They lay pelagic eggs.[3] Their diet is made up of fishes and crustaceans.[5] In the wild these fish are largely solitary.[6]

Utilisation[edit]

Cirrhitichthys aureus are not often collected for the aquarium trade.[5][6]
