What animals carry their young on their back?

Answer:
Monkeys and Gorillas mainly.

Certain marsupials continue to carry their young on their back for several months, once the joeys have emerged permanently from the pouch. These are mainly the arboreal marsupials. Possums, koalas, quolls and cuscuses exhibit this behaviour.
