This study reports a second case of parthenogenesis in a zebra shark female that was housed with conspecific mature males, questioning the conditions under which elasmobranch females undergo parthenogenesis.
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.
