Etymology: Rhinecanthus: Greek, rhinos = nose + Greek, akantha = thorn (Ref. 45335).
Eponymy: Pablo Ruiz Picasso (1881–1973) was a Spanish painter and sculptor. The vivid patterns and colours of Rhinecanthus triggerfish have led to them being popularly known as picassofish. (Ref. 128868), visit book page.

Commonly found in subtidal reef flats and shallow protected lagoons, Ref. 48637. Benthopelagic (Ref. 58302). Juveniles secretive with rubble patches, adults swim about openly but are usually shy (Ref. 48637). Territorial. Feed on algae, detritus, mollusks, crustaceans, worms, sea urchins, fishes, corals, tunicates, forams, and eggs (Ref. 3921). Oviparous (Ref. 205). Sleep on its side; makes a whirring noise when alarmed (Ref. 4420). Also caught with drive-in nets and is considered a popular aquarium fish (Ref. 9770).
Lebenszyklus und Paarungsverhalten
Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fruchtbarkeit | Larven
Distinct pairing (Ref. 205). Mating system may be a mixture of polygyny, monogamy, and potential promiscuity in solitary females but the primary mating system considered for this species is polygyny (Ref. 116439). Females are territorial, solely tending and guarding the eggs (Ref. 116451). Males exhibit polygyny (Ref. 116451).
