Pseudobiceros bedfordi
Note, Pseudoceros bedfordi has been moved to Pseudobiceros bedfordi (Faubel 1984) because it has duplicate male reproductive systems. In the image below showing two animals just before copulation, the two penis papillae can be seen.

Comments A quite rare photo document showing the complex mating behaviour of marine polyclads which has been recently described as an act of hypodermic insemination. During copulation worms were observed to move towards each other, touch, then roll around together (= "rearing up" - left photo), simultaneously everting their penis papillae and stylets outward. They then try to stab each other anywhere (= "penis fencing" - right photo). When one animal is successful in penetrating the other, it holds on with its stylet embedded in the epidermis of its partner and spermatozoa are transferred.

Check out the introductory page to learn more about the mating behaviour of marine polyclads!
