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).

Ecologia
marino associati a barriera corallina; distribuzione batimetrica 2 - 25 m (Ref. 9785). Tropical; 24°N - 27°S, 94°E - 172°E (Ref. 3810)

Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 28.0 cm TL maschio/sesso non determinato; (Ref. 9710); common length : 15.0 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 or almost to posterior nostrils. Lower limb of preopercle scaly. Antrorse (forward-directed) suborbital spine absent. Pelvic fins long, reaching almost to or beyond level of origin of anal fin. Color: Upper body olive, white below. 2 pearly white stripes on snout in front of eyes. Lower lobe of caudal fin reddish. Juveniles white, with a narrow black stripe along back (only on some specimens) and black midlateral stripe. Some with a yellowish ventral surface. Presence of a black spot between first four dorsal spines. Some color variation between Indian and Pacific populations: juveniles lack yellow stripe in the Indian Ocean population and adults show a contrasting dark back compared to Pacific form (Ref. 48635).
Found on sand bottoms close to reefs. Feed on crustaceans, polychaete worms, mollusks and small fishes (Ref. 3810, 9785). Juveniles may be Batesian mimics of poison-fang blennies, Meiacanthus spp. (M. geminatus and M. vittatus) (Ref. 37816, 90102). It is parasitised by the monogenean Anoplodiscus hutsonae on the pectoral fins and body surface (Ref. 124057).
