How do Tasmanian devils raise their babies?

The Tasmanian devil is a marsupial so, like most (not all) marsupials, it has a pouch to protect its joeys while they are developing. The young joeys are born extremely undeveloped and must compete for a teat in the pouch. Tasmanian devils can actually give birth to up to 20 joeys at a time, but having only four teats, this means most of the young die.
