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 - 40 m (Ref. 89972), usually - m (Ref. ). Tropical; 0°C - ; 30°N - 30°S
Pacific Ocean: Ryukyu Islands to the Great Barrier Reef and the Hawaiian, Marquesan and Ducie islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 48636)
Relatively common on exposed seaward reefs; occasionally on shallow lagoon reefs in areas of rich coral growth and clear water. Juveniles in protected coral areas (Ref. 48636). Benthopelagic (Ref. 58302). In pairs in Indonesia but schools in some Pacific locations (Ref. 48636). Often in pairs during breeding and feed mainly on scleractinian coral polyps. Easily approached (Ref. 9710). Oviparous (Ref. 205), monogamous (Ref. 52884).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
