A hermaphroditic Port Jackson shark, Heterodontus portusjacksoni , with complete and separate female and male reproductive tracts

One of 353 Port Jackson sharks, Heterodontus portusjacksoni, caught o¡ the southern coast of Western Australia, was a hermaphrodite. The female reproductive tract consisted of a large (functional) right ovary with three large yolked ova, a small non-functional left ovary and two well-developed uteri and oviducal glands. The male tract comprised two conspicuous but undeveloped testes, two vas deferens and two calci¢ed claspers with grooves. This individual represents the ¢rst published example of hermaphroditism in the order Heterodontiformes and is a rare example of an elasmobranch with a complete suite of both male and female reproductive structures.
