Abstract

Of 929 piked spurdogs, Squalus megalops, collected in south-eastern Australia, one individual was hermaphrodite. This individual presents a rare case of abnormal hermaphroditism in sharks where the female reproductive tract (left side) possessed a mature yolky ovarian follicle but completely undeveloped uterus and oviducal gland, and the male reproductive tract (right side) was fully developed. The hermaphrodite was found schooling with mature males. The morphological and behavioural characteristics suggest that this individual would function as a normal male.
