Flatworm uses 'hypodermic penis' to inject sperm into own head

The pursuit of reproductive success in the animal kingdom sometimes calls for extreme measures. But few creatures can match the hermaphrodite flatworm, which scientists have discovered can reproduce by injecting sperm into its own head.

The tiny aquatic worm, Macrostomum hystix, is able to self-fertilise because it produces both eggs and sperm. Although it prefers to reproduce with other flatworms, when no mating opportunities are present it resorts to using its needle-like penis to inject sperm into its own head.

The sperm then swim down the creature’s transparent body to fertilise eggs in the tail region, leading to viable offspring.

“...hypodermic penis...inject sperm into own head...” That doesn’t sound like a lot of fun.

New territory for Apple. Forget the watch, what you need is a hypodermic penis that injects sperm into your head.
