Summary:
A reddish-brown to pale greyish-brown rockcod becoming darker towards the rear, with distinctive whitish to pale blue oblique stripes across upper and lower lobes of the tail, often six faint bars along the side that divide ventrally, small orange-red spots on the head and nape, and a pair of dark spots on the front of the lower lip. The Flagtail Rockcod also has yellowish pectoral fins and usually a large reddish to brownish spot on the outer margin of the gill cover.

Although once considered to be widespread in the Indian Ocean, the Flagtail Rockcod is known from Christmas Island in the eastern Indian Ocean to French Polynesia and the Pitcairn Islands. The Indian Ocean species is Cephalopholis nigripinnis, which hybridizes with C. urodeta at Christmas Island.

Distribution

Claremont to Rowley Shoals, Western Australia, Ashmore Reef, Timor Sea, and the northern Great Barrier Reef and reefs in the Coral Sea, to at least the Solitary Islands, New South Wales; also at Christmas Island in the eastern Indian Ocean, and the Lord Howe Island region in the Tasman Sea. Elsewhere the species occurs in the tropical, east-Indo-west-central Pacific - from Christmas Island to French Polynesia and the Pitcairn Islands.
Usually inhabits clear, shallow outer reef areas in depths to 60 m; occasionally also in lagoons, back-reef areas, and reef crests.

Features

Dorsal fin IX, 14-16; Anal fin III, 8-9.
Greatest body depth 2.7-3.1 in SL; HL 2.4-2.7 in SL; interorbital area convex; preopercle rounded, finely serrate with fleshy lower edge; subopercle and interopercle usually smooth; maxilla reaching well beyond eye; caudal fin rounded; pelvic fin 1.8-2.2 in HL; pectoral fin distinctly longer than pelvic fin; caudal fin rounded; body scales ctenoid; snout and maxilla with minute cycloid scales.
