They do have home territories, but they will not stay in one particular tree. The koala is an arboreal animal. Arboreal means âliving in treesâ. Koalas live, eat, and sleep in the top branches of eucalyptus trees, also known as gum trees. Males koalas have a special area on their chest that leaves a scent. They rub their chests on their âhome treesâ to leave their scent and mark the trees as their own.
