Mounting between females is known from insects, birds and
mammals. Female bonobos (Pan paniscus) show a mounting behavior which physically
differs from other primate species. They embrace each other ventro-ventrally and rub their
genital swellings laterally against each other. Although many functions were suggested, so
far none has been object of detailed investigation.
