Parthenogenesis in an elasmobranch in the presence of conspecific males
K.A. Feldheim, J. Dubach, L. Watson
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.
