Marsupials were a subgroup of mammals whose members were born one at a time incompletely developed and were typically carried and nursed in a pouch on the mother's belly. Although they were in fact reptomammals, the wampas of Hoth could be considered marsupials in terms of their mating process, as their cubs were developed within their mothers' pouches for a period of roughly three months. Similarly, the reptilian Hutts were normally nourished in a brood pouch for the first fifty years of their life.
