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.
