Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Chaetodontidae
Etymology: Chaetodon: Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Forsskål.
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 1 - 35 m (Ref. 11441). Tropical; 30°N - 20°S
Length at first maturity / Size / Weight / Age
Maturity: Lm 13.0  range ? - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 4859)
(total): 12 - 13;
soft rays: 19 - 21. There is a pattern of `chevron' markings on the sides and a prominent black spot at the posterior edge of the soft portion of the dorsal fin. Adults of this species have a prominent black vertical band running across the eye, and a filament trailing posteriorly from the upper soft portion of the dorsal fin. Juveniles with a black bar over the head that hides the eye and an eye-sized black spot on the soft dorsal fin (Ref. 48636).
Indo-Pacific: Red Sea and East Africa (extending to Mossel Bay, South Africa, Ref. 5372) to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to Lord Howe and Rapa islands.
May be seen in a variety of habitats ranging from rich coral reefs (Ref. 58652) to weedy and rubble covered areas (Ref. 1602). Benthopelagic (Ref. 58302). Maybe found singly, in pairs, and in aggregations that roam over large distances in search of food. Feed mainly by tearing pieces from polychaetes, sea anemones, coral polyps, and algae (Ref. 1602). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
