Cyphopods, also known as vulvae, are paired sacs in female
millipedes that located on the underside of the third body segment that store sperm and connect to the
oviduct. Cyphopods are sclerotized, and usually hidden behind a small opening. Despite the connotation of the suffix -''pod'' (generally referring to legs or feet), cyphopds are not derived from walking legs.
