Consecutive parthenogenetic births in a spotted eagle ray Aetobatus narinari

J Fish Biol. 2016 Feb;88(2):741-5. doi: 10.1111/jfb.12819. Epub 2015 Nov 12.

Abstract

Genetic evidence is given to support consecutive parthenogenesis in a spotted eagle ray Aetobatus narinari using nuclear microsatellite genotyping. To date, only a handful of births involving the parthenogenesis process in chondrichthyans have been verified using microsatellite markers and even fewer verified as recurring births. This appears to be the first documented case of this process occurring in a myliobatid species.

Keywords: DNA; automixis; elasmobranch; myliobatid; reproduction.
