Short description
ຕົວທີ່ໃຊ້ໃນການຈຳແນກຊະນິດ | ສະລີລະວິທະຍາ | ການວັດແທກຮູບຮ່າງລັກສະນະພາຍນອກຂອງດິນ,ສັດ,ປາ…
ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 60; ຄີກົ້ນຂອງປາ: 53 - 55; ສັດທີ່ມີກະດູກສັນຫຼັງ: 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).
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).
