It is turned downwards and carries a pair of brood-pouches in the female Cladocera. It serves as locomotory organ in Copepods where the males also use it as clasping organ. Hexapoda are traditionally shown to be monophyletic or descended from one evolutionary group. The head is composed of a presegmental acron that usually bears eyes (absent in Protura and Diplura), followed by six segments, all closely fused together, with the following appendages: Segment I.
