Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
duri punggung lunak (Keseluruhan (total)) : 60; Sirip dubur lunak: 53 - 55; vertebrata, bertulang belakang: 63 - 64. The species is distinguished from its congeners by the following set of characters: D 60; A 53-55; pectoral-fin rays 20-21; caudal-fin rays 6; vertebrae 63-64; dorsal contour of head rounded to snout, covered with gelatinous tissue; short snout with rounded tip projecting past upper jaw; small mouth, horizontal, inferior, with cleft reaching to nearly vertical below center of eye; large eye with dorsal margin level with or slightly above top of gill
opening; large opercular flap, rounded, projecting slightly toward dorsal; upper lobe of pectoral fin with 15 rays, one in
notch, and 4 or 5 in lower lobe, both lobes extending beyond anal-fin origin; cephalic pores are equal to or smaller in diameter than nostril; suprabranchial pore elevated, anterior of gill opening a distance about equal to opercular flap width; 3 pyloric caeca (Ref. 82595).
Body shape (shape guide): elongated.
The male (5.30 and 6.20 cm) specimens appear to be mature, while the female (9.40 cm) was mature with ovaries containing numerous mature and immature, spherical, pale-colored, opaque, yolked oocytes, ranging in diameter from 0.20-2.12 mm; from gross observation, there appear to be fewer than 100 eggs in each ovary. Specimens were collected with a 60 cm bongo net, epibenthic sled and bottom trawl (Ref. 82595).
