-------------------------
Description
Dorsal spines (total): 7; Dorsal soft rays (total): 10-11; Anal spines: 1; Anal soft rays: 9-10; Pectoral fin rays: 19-20; Longitudinal scale series: 22-24; Predorsal scales: 4; Ctenoid scales on body, becoming cycloid anterior to pelvic and pectoral fins. Depth of body: 3.7-4.0 in SL. Spines on rear edge of preopercle: 3-7, lowermost often larger than others; Rounded caudal fin; Pelvic fins united medially, disc-like; Fourth dorsal spine, forming long filament in adult. Max. length: 4.6 cm SL. Depth range: 1 - 30 m.
Color
Thick dark bar under the eye, a short dark bar on the tail base, and a black spot at the front of first dorsal fin. A diffuse black spot (about size of pupil) usually present between first and second spines of first dorsal fin; Black vertical suborbital bar broadened and rounded ventrally.
Etymology
Asterropteryx: from Greek prefix, a- , an- = not, without, (having) no + from Greek, sterrhos, -a, -on = firm, solid + from Greek, pteryx = fin. Referring to slender and flexible dorsal-fin spines.
spinosa: from Latin, spinosa = spiny. Referring to five bony, spine-like projections on preopercle.
Original description: Oplopomus spinosus Goren, 1981 - Type locality: north coast of Maitre Island, New Caledonia, depth 3-5 meters.
Distribution
Indo-West Pacific: Seychelles and Maldive Islands to Fiji and Tonga, north to Ryukyu Islands (Japan), south to Australia and New Caledonia.
Biology
Inhabits lagoon reefs. Found on sandy and muddy bottoms of coral rubble.
