Actinopteri (ray-finned fishes) > Acanthuriformes
(Surgeonfishes) > Chaetodontidae
Etymology: Parachaetodon: Greek, para = the side of + Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Cuvier.
It is unclear if Chaetodon oligacanthus Bleeker, 1850 is a distinct species in Parachaetodon, taking into accont that it is the type species of the genus. The species page will be created in the next update. This species is valid in Eschmeyer (CofF ver. May 2011: Ref. 86870). Please send references, or more studies are needed.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 5 - 40 m (Ref. 90102), usually - m (Ref. ). Tropical; 0°C -

Occur in pairs on flat sand or silty bottoms on coastal reefs. Adults school in large numbers over open muddy substrates in deep water. Juveniles sometimes in large lagoons with seagrasses in depths of about 5 m or more (Ref. 48636). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
