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).

Dorsale stekels (totaal) : 10; Dorsale zachte stralen (totaal) : 9; Anale stekels: 3; Anale zachte stralen: 7. This species is distinguished by the following set of characters: head is scaly except for subopercle which is naked with numerous small pores; scales on top of the head reaching forward to between the anterior nostrils and snout tip; lower margin of the eye tangent to a line from snout tip to upper pectoral-fin base; suborbital with a large retrorse spine (a small antrorse spine may also be present on third infraorbital, immediately above suborbital spine); posterior margin of the preopercle is rugose, bearing one or two rows of short blunt spines along its length; second anal-fin spine is longer and more robust than first or third anal-fin spines. Colouration: most body scales, except for breast and caudal peduncle, with greenish yellow spot (spots darker in live fish); caudal peduncle often yellowish; with a broad white bar from nape onto operculum; suborbital with obscure, rectangular, white patch; white band beneath lateral
line never present; the upper limb of opercular margin blackish, while lower limb reddish orange; upper base of pectoral fin with a small wedge-shaped dark spot; fins are yellow (Ref. 130620).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Occurs over mud bottoms near reefs or in open sand areas in turbid waters and usually observed underwater solitary or in pairs (Ref. 130620).
