(Threadfin breams, Whiptail breams)
Etymology: Scolopsis: Greek, skolex = worm + Greek, opsis = appearance (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 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. This species has been previously reported as Scolopsis dubiosus (a junior synonym of Scolopsis taeniopterus), or misidentified as Scolopsis temporalis.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 38.0 cm TL male/unsexed; (Ref. 90102); common length : 18.0 cm SL male/unsexed; (Ref. 3810)
soft rays: 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.
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.
