简单描述 检索表 | 型态特徵 | 形态测量图

This species is distinguished by the following set of characters: slender body of moderate size, depth 9-10.6% TL; relatively narrow and very short snout, horizontal prenarial length is 8.4-9.1% TL; large eyes, length 5.1-5.6% TL; secondary lobe of anterior nasal flap is well developed; small dorsal fins that are strongly raked; first dorsal-fin spine is moderate, broad-based while the second dorsal-fin spine is moderate, robust and broad-based; weakly falcate pectoral fin in adults its inner margin relatively short, 6.9-7.8% TL; caudal fin with a short, broad caudal bar, enlarged upper caudal blotch and the fringe is located distally on lobe in juveniles; flank denticles are broadly unicuspidate to weakly tricuspidate; monospondylous centra 35-38, precaudal centra 72-76, total centra 96-100 (Ref. 58445).

生物学特性     字汇 (例如 epibenthic)

Apparently occurs on or near the bottom of upper continental and insular slopes, but depth distribution is undetermined; probably on shallower water than its congeners. Presumably feeds on small fishes, cephalopods and crustaceans. Viviparous, with yolk-sac dependency. Gives birth to 3 -10 pups, but gestation period is unknown. Males mature at about 43 cm TL and females by 61 cm TL; with largest embryo measured at 18 cm. The species is a very common catch component fo the demersal longline fishery in deepwater areas in eastern Indonesia. It is caught for its meat, fins and liver oil (Ref. 58042).
