Note
The capture of recently inseminated or pregnant specimens of Carcharias taurus, Isurus paucus, I. oxyrinchus, Alopias superciliosus and A. vulpinus has allowed new information to be obtained on the reproductive biology of these species. Oophagy and embryonic cannibalism (adelphophagy) have been documented in C. taurus, but only oophagy in other lamnoid species.
