Some planarians (such as the genera Planaria, Artioposthia, Arthurdendyus, Coleocephalus and Newzealandia) have a series of finger-like projections, called adenodactyls, near the male and female atria. Adenodactyls contain glands and produce several secretions believed to be useful during reproduction. [7]
