زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Inhabits sandy and muddy bottoms, from the intertidal zone to about 100 m. Sometimes near rocky reefs (Ref. 12951). Slow swimming over bottom or partially buried. Feeds on benthic invertebrates, mainly crustaceans and small fishes. Males mature at ca. 56 cm TL, females at ca. 64 cm TL; born at ca. 25 cm TL (Ref. 114953). Ovoviviparous, one or two litters per year with 4-10 embryos.

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). One or two litters per year, of 4-10 embryos (Ref. 6675)
