A number of species reproduced hermaphroditically. For instance, individual Hutts contained both male and female reproductive organs. Other hermaphroditic species included the Pui-ui, the Verpine, and Strills. Another example of a hermaphrodite species is the Vratix. A Vratix individual would, during its life assume both the role of impregnator and gestator "male" and "female", depending on its age.
