Parthenogenesis in an elasmobranch in the presence of conspecific males

Kevin A Feldheim et al. J Fish Biol. 2023 Feb.

Abstract

Parthenogenesis has been observed in several elasmobranch species, primarily in public aquaria. The majority of cases of parthenogenesis have occurred either when females were held without males or once a male was removed from a female's habitat. Here we report a second instance of parthenogenesis in a zebra shark female that was housed with conspecific mature males. This study calls into question the conditions under which elasmobranch females undergo parthenogenesis.

Keywords: elasmobranch; microsatellite; parthenogenesis; zebra shark.
