Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335 ) .  More on author: Valenciennes .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; reef-associated; depth range 1 - 25 m (Ref. 90102 ).   Tropical; 30°N - 13°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: Maldives to New Ireland in Papua New Guinea, including Cocos-Keeling Islands, north to Ryukyu Islands and south to the Philippines, including Palau. This species is the terminal male of Scarus singaporensis . Possibly replaced by Scarus falcipinnis in the western Indian Ocean (Ref. 2689 ).

Size / Weight / Age

Maturity: L m   ?   range ? - ? cm
Max length : 70.0 cm TL male/unsexed; (Ref. 9710 )

Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines : 3; Anal soft rays : 9. Scales large. Median predorsal scales 6; 3 scale rows on cheek, with 1-3 scales in ventral row. Caudal fins emarginate in initial phase to deeply concave in large terminal phase. Lips nearly covering dental plates; terminal males with 0-2 canines posteriorly on side of upper plate, none on lower. The initial phase closely resembles that of S. altipinnis (Ref. 1602 ). The terminal phase has the distinctive brilliant green throat and lacks the filamentous middle dorsal spine (Ref. 1602 ).

Biology     Glossary (e.g. epibenthic)

Found in seaward slopes and reef flats (Ref. 90102 ). Usually associated with outer reefs but will enter shallow water in protected areas. Often in large schools (Ref. 9710 ). Grazes on benthic algae (Ref. 3488 ). Also caught with nets and other types of artisanal gear (Ref. 2689 ). Minimum depth of 1 m reported from Ref. 30874.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing during breeding (Ref. 205 ).
