Vernacular names
Cirrhitichthys is a genus of marine ray-finned fish, hawkfishes from the family Cirrhitidae. They are found on tropical reefs in the Indian and western Pacific oceans. Some species can be found in the aquarium trade.

Taxonomy

Cirrhitichthys was first formally described in 1857 by the Dutch ichthyologist Pieter Bleeker. The type species designated by Bleeker was Cirrhites graphidopterus which had been described by him in 1853,[1] although this taxon has subsequently been considered a synonym of Cirrhites aprinus which Georges Cuvier had described in 1829.[2] The name of this genus is a compound of Cirrhitus, referring to the similarity between the two genera, although there are differences in dentition, and ichthys meaning “fish”.[3]
Species

The currently recognized species in this genus are:[4]

Cirrhitichthys aprinus (G. Cuvier, 1829) (spotted hawkfish)
Cirrhitichthys aureus (Temminck & Schlegel, 1842) (yellow hawkfish)
Cirrhitichthys bleekeri F. Day, 1874
Cirrhitichthys calliurus Regan, 1905 (spottedtail hawkfish)
Cirrhitichthys falco J. E. Randall, 1963 (dwarf hawkfish)
Cirrhitichthys guichenoti (Sauvage, 1880)
Cirrhitichthys oxycephalus (Bleeker, 1855) (coral hawkfish)
Cirrhitichthys randalli Kotthaus, 1976

Characteristics

Cirrhitichthys hawkfishes have an oval, moderately compressed body with a sharp, more or less straight-profiled snout. The anterior nostril has a tuft of cirri on its posterior margin. The mouth is moderately large with a row of small canine-like teeth on the jaws and a band of simple teeth within the outer band. There are patches of teeth on the middle and sides of the roof of the mouth. The margin of the preoperculum has quite large serrations and the gill cover has 2 flattened spines. The dorsal fin is continuous, with 10 spines and 11-12 soft rays, there is a slight incision between the spines and the soft rays. The membranes between the dorsal fin spines deeply notched and each spine has a sizeable tuft of cirri at its tip. The anal fin has 3 spines and 5-7 soft rays. The caudal fin is truncate. The lower 5-7 pectoral fin rays are robust with deep incisions in the membranes between them and they are notably longer than the other rays. The upper 1-2 and lower 6-7 pectoral fin rays are simple. The pelvic fin has a single spine and 5 soft rays and has its origin to the rear of the base of the pectoral fin.[5] Their total length varies from 7 cm (2.8 in) in the dwarf hawkfish (C.s falco) and 14 cm (5.5 in) in the yellow hawkfish (C. aureus).[4]
Distribution and habitat

Cirrhitichthys hawkfishes are mainly found in the Indo-West Pacific[4] with one species, the coral hawkfish (C. oxycephalus) extending into the eastern Pacific.[5] These fishes are associated with coral and rocky habitats.[6]
Biology

Cirrhitichthys hawkfishes are predatory, using the "sit and wait" technique to ambush benthic prey which can be invertebrates or fish, perching on their thickened lower pectoral fin rays among sponges and corals.[7] They are protogynous hermaphrodites, all start out as female and live in harems, if the male is lost the largest and more dominant female will change sex.[8] They are pelagic spawners rising upwards into the water column in pairts to spawn.[9]
Utilisation

Cirrhitichthys hawkfishes are collected for the aquarium trade.[8]
