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 δN compared to their mothers (0·82 and 0·88‰, respectively), but fractionation of δC varied. Embryonic S. lewini were enriched (1·00‰) in δC while C. limbatus were depleted (0·27‰) relative to their mothers. [ABSTRACT FROM AUTHOR]
