زيست شناسي     واژه نامه (بعنوان مثال 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).
