生物学特性     字汇 (例如 epibenthic)

Dasyatis margarita is a coastal marine species, entering lagoons, shallow bays and estuaries (Ref. 3497, 81259). Feeds on shrimps, crabs, bivalves and annelids (Ref. 28587). Ovoviviparous (Ref. 50449).

常见于海洋与河口的栖息地。 (参考文献 3497) 吃虾,螃蟹,二枚贝与环节动物。 (参考文献 28587) 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). Distinct pairing with embrace (Ref. 205).東大西洋: 茅利塔尼亞到安哥拉。
