Taxonomic Remarks
Considered valid in McEachran and Seret 1990 (Ref. 4441) but with a note that more recent authors consider it to be immature stages of R. marginata. Further study is needed to clarify problem (Ref. 4441). Tentatively valid in Last et al., 2016, for these differ subltly in their morphology (Ref. 114953:719).

Found in tropical to warm temperate coastal waters, but absent from islands of western Pacific. Often forming large groups swimming near the surface and quite destructive of commercial oyster and clam beds. Feeds on bottom-living mollusks, crustaceans and fishes. Seldom marketed. Ovoviviparous, gestation period up to one year with 2-6 embryos produced.
发现于热带到暖温带沿岸水域了, 但是西太平洋的岛没有出现。 时常形成游近表面的大的群而且对商业的牡蛎与蛤床相当具毁灭性。 吃底栖软件动物，甲壳动物和鱼类。 很少在市场上销售。 卵胎生的, 妊娠时期向上到一年用 2-6 ，胚胎生产。

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).東大西洋: 西班牙到塞內加爾南部, 包括地中海。
