Actinopteri (ray-finned fishes) > Acanthuriformes
(Surgeonfishes) > Chaetodontidae
Etymology: Chaetodon: Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 36 m (Ref. 1602). Tropical; 30°N - 30°S, 77°E - 124°W
Indo-Pacific: Sri Lanka to the Hawaiian, Marquesan and Ducie islands, north to southern Japan, south to Lord Howe and Rapa Islands; throughout Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 9710)
(total): 12 - 13;
soft rays: 20 - 23. Body is white with orange to orange-brown oblique bands on the sides. Two broad yellow-edged black bars are on the head; one running across the eye and another on the snout (Ref. 4855). Snout length 2.6-3.2 in HL. Body depth 1.3-1.6 in SL (Ref. 90102).
Occur in clear waters and coral-rich areas of lagoon and seaward reefs. However, only common in seaward reefs (Ref. 1602). Benthopelagic (Ref. 58302). Juveniles are solitary, living among branching corals, while adults are almost always in pairs and are home-ranging. Feed exclusively on coral tissue (Ref. 1602). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Monogamous mating is observed as obligate, genetic and social (Ref. 52884).
