Apparently koala fighting for territory results in one of the males backing down 96% of the time. The other 4% of the time it’s on like an MMA fight, but fluffier, and in a tree.
A fight erupts between two koalas after one of the males invades the other’s territory. Watch a scene from Cracking the Koala Code which premiered May 16, 2012 on PBS Nature.
