生物学特性     字汇 (例如 epibenthic)

This benthic inshore species is found over soft bottoms to at least 50 m; feeds on benthic crustaceans and polychaetes. Gestation last about a year, produces litters of 1-8 pups in autumn (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size for males at 43-45 cm TL, females at 42-48 cm TL; birth size at 13-16 cm TL (Ref. 114953).

卵胎生的.(参考文献 50449)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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).西南大西洋。
