Meet Yaku the koala and her joey Wabi! Koalas are a type of mammal called marsupials, and most marsupials like koalas have pouches where their babies develop. Do you like to climb? Climbing is one of Yaku and Wabi’s favorite things to do. Living all across East Australia, koalas make their homes in tree canopies. You can help protect koalas by raising awareness in your community about threats facing them like bushfires, deforestation, and disease.
