What it does
Pseudoceros canadensis are simultaneous hermaphrodites that use a form of hypodermic insemination known as penis fencing to determine which breeding partner is the female, and which is the male. Gametes are passed from the victorious male into the female by puncturing the body wall and injecting them with gametes. After fertilization, eggs are laid and develop into Muller's larvae (a free-swimming larval stage).
