Pseudobiceros Bedfordi is a type of flat worm. They are fast moving and swim by indulating their bodies. They are hermaphroditic organisms. This means that they have both female and male reproductive organs. These organsims have two penises on the underside of their body. During mating they perform a ritual called Penis Fencing. This is a process by which the flatworms try to stab one aother with their penises and inject their sperm into the other. The sperm can be injected into any part of the body that tho other flatworm can puncture. The sperm then travels to the ovaries that are held inside the body . Every single worm contains a set of ovaries. The stream of sperm can be seen traveling through the flatworms body. Depicted to the left is a pair of Bedford's flatworms . One is injecting the sperm into the other and therefore becoming the father. The purpose for the penis fencing is to become the father. The mother has to bear the burden of the children inside her.
