زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Found on the continental shelf from close inshore to about 150 m depth (Ref. 9997). Found throughout the water column but usually near the sea bed during the day and near the surface at night (Ref. 6390). Prefers teleost fishes but also feeds on cephalopods to a lesser degree. Viviparous (Ref. 50449). Forms large aggregations (Ref. 6871). Utilized for its meat and fins (Ref. 6871). The flesh has a relatively high mercury content (Ref. 6871).

Life cycle and mating behavior بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)
