does a possum carry newborns in a pouch or have a nest?

A possum, specifically the Virginia opossum, carries its newborns in a pouch. Female opossums have a marsupial pouch where the tiny, underdeveloped babies attach to a teat for nourishment and continue to grow. After they outgrow the pouch, the young may ride on their mother's back while she forages for food. Opossums do not build traditional nests; instead, they often use dens or burrows for shelter.
