Abstract

Stable-isotope values of a scalloped hammerhead Sphyrna lewini and blacktip shark Carcharhinus limbatus and their respective embryos were analysed. Embryos of both species were enriched in δ ¹⁵ N compared to their mothers (0·82 and 0·88‰, respectively), but fractionation of δ ¹³ C varied. Embryonic S. lewini were enriched (1·00‰) in δ ¹³ C while C. limbatus were depleted (0·27‰) relative to their mothers.
