The arc-eye hawkfish (Paracirrhites arcatus), the ringeye hawkfish, horseshoe hawkfish or whiteline hawkfish, is a species of marine

hawkfish belonging to the family Cirrhitidae. It is found in shallow waters in the tropical Indo-Pacific on reefs
, resting on coral heads much of the time.

Taxonomy

The arc-eye hawkfish was first formally

Fishbase treats this taxon as a synonym of P. arcatus.[2]

Description

Arc-eye hawkfish at Kona, Hawaii

The arc-eye hawkfish has a relatively deep body, the

caudal fin.[5] The dorsal fin contains 10 spines and 11 soft rays while the anal fin has 3 spines and 6 soft rays, each dorsal fin spine being tipped with a branched cirrus.[6] This species reaches a maximum published total length of 20 cm (7.9 in).[2] This species has a variable background colour on the body, the typical colour being pale pinkish brown.[7] There is a horseshoe-shaped mark to the rear of the eye that consists of three thin lines. The gill cover has three orange bands set in a light blue area. A white to pink stripe is frequently present from around halfway along the flank and running to the rear.[8]

Distribution and habitat

The arc-eye hawkfish is widespread in the tropical

Ashmore Reef in the Timor Sea, and from the northern Great Barrier Reef and reefs in the Coral Sea south to the Solitary Islands in New South Wales. It has also been recorded at the Australian Indian Ocean territories of Christmas Island and the Cocos (Keeling) Islands; and the Tasman Sea locations of Middleton Reef, Elizabeth Reef and Norfolk Island. It is a benthic species associated with coral reefs. It usually can be found in lagoon and seaward reefs, at a depth of 1–30 m (3 ft 3 in – 98 ft 5 in), with a maximum of 91 m (299 ft).[2]
