Do marsupials have a cloaca?

Best Answers

I think the thing that's throwing you off is that the marsupial genital tract is distinct from the urinary tract. That is, in the male marsupial, urine isn't excreted via the penis. Rather, it comes out of the cloaca/anus. I think that's the clearest way to think about a cloaca: are urine and feces excreted from the same place. read more

Marsupials have somewhat of a mosaic condition between the primitive condition (cloaca) and the configuration in placental mammals. Depending upon whether or not one's definition of"cloaca" includes the genital tract is the semantic issue here. read more

Yes. A cloaca is present in marsupials and monotremes, as well as in birds, amhibians and reptiles. Placental mammals do not have a cloaca. read more

Unlike other marsupials, marsupial moles have a true cloaca, a fact that has been used to argue against a marsupial identity for these mammals. Placentals. Most adult placental mammals have no remaining trace of the cloaca. read more
