    The flatworm, Macrostomum hystrix, is able to use this reproductive strategy as they have both male and female sex organs. Though this produces ‘inbred’ offspring, it’s still better than not being able to reproduce at all, researchers suggest.

    Normally, these flatworms reproduce by exchanging sperm with others using their stylet – a sharp, needle-like protrusion – to penetrate their partner’s outer body membrane in a process that scientists describe as ‘traumatic insemination.’
