Nemipteridae (Threadfin breams, Whiptail breams)
Etymology: Scolopsis: Name from the Greek masculine noun 'skolos' meaning 'thorn' and suffix '-opsis' (from Greek feminine n. 'opsis' meaning 'aspect', 'appearance') meaning ‘thorny appearance’ presumably referring to 'les dentelures de la préopercule, en ont aussi, et même d'épineuses, aux sous-orbitaires' mentioned by Cuvier (1814) in his designation of the genus. Name ending in -'opsis' are treated as feminine according to ICZN 1999: Article 30.1.2 (Ref. 130620).
More on author: Cuvier.

Ecologia
marino associati a barriera corallina; distribuzione batimetrica 2 - 50 m (Ref. 90102). Tropical; 32°N - 31°S, 90°E - 157°E (Ref. 3810)
Indo-West Pacific: eastern Indian Ocean (Andaman Sea and northwest Australia) to Papua New Guinea, north to the Ryukyu Islands, south to northeastern Australia.

Size / Peso / Age
Maturità: Lm ? range ? - ? cm
Max length : 38.0 cm TL maschio/sesso non determinato; (Ref. 90102); common length : 18.0 cm SL maschio/sesso non determinato; (Ref. 3810)
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 9; Spine anali: 3; Raggi anali molli: 7. Head scales reaching to between anterior margin of eyes and posterior nostrils. Lower limb of preopercle scaly. Antrorse (forward-directed) suborbital spine absent. Pelvic fins long, reaching almost to level of origin of anal fin. Upper lobe of caudal fin a little longer than lower lobe. In larger specimens, lobes produced to form short filamentous extensions in larger specimens. 3 blue stripes on snout; uppermost joining eyes above nostrils. A blue stripe on preopercle behind eye. A blue chevron-shaped stripe running upwards onto opercle from below eye and bending downward towards pectoral-fin base.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Occurs on sand bottoms close to reefs. Often silty habitats (Ref. 48635). Occurs solitary or in small groups. Feeds on small fishes, crustaceans, mollusks and polychaete worms (Ref. 90102). It is parasitised by the monogenean Anoplodiscus hutsonae on the pectoral fins and body surface (Ref. 124057).
