Biology & Feeding
The Pink Flatworm is a predator. It feeds on a variety of creatures. These include moss animals, cnidarians, crustaceans, tunicates and other molluscs.
The mating ritual of Prostheceraeus roseus is very combative. Although they are hermaphrodites, each of them wants to be the male part. They ‘fight’ with their penises, each of which has two, like swords. The winner is the one who first injects his sperm into the other and the loser must carry the eggs.
