И матки 2, а влагалища по некоторым данным вообще 3 - одно специально для родов. А мочатся самцы вообще как-то по-другому, на это моих познаний английского не хватило, чтобы перевести. Marsupials' reproductive systems differ markedly from those of placental mammals (Placentalia). Females have two lateral vaginas, which lead to separate uteruses, but both open externally through the same orifice. A third canal, the median vagina, is used for birth. This canal can be transitory or permanent.[19] The males generally have a two-pronged penis, which corresponds to the females' two vaginas. The penis is used only for discharging semen into females, and there is instead a urogenital sac used to store waste before expulsion.http://en.wikipedia.org/wiki/Marsupial
