Title
Mother–offspring isotope fractionation in two species of placentatrophic sharks
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 δ15N compared to their mothers (0·82 and 0·88‰, respectively), but fractionation of δ13C varied. Embryonic S. lewini were enriched (1·00‰) in δ13C while C. limbatus were depleted (0·27‰) relative to their mothers.
