WILDLIFE -- The Matchless Marsupial: Koala

A representative animal in the Otway Forest, south of Melbourne, Australia, is the koala. Here, their population density is extremely high, with up to six individuals living in a single tree. In this koala paradise, males are amazingly active as they grunt, chase each other on the ground, and engage in intense fights over females. In an interesting twist, on average, koalas are awake for a total of only four hours a day. Each day and each night, they repeat the cycle of spending an hour eating eucalyptus leaves and then sleeping for a few hours. Recent studies have led to an interesting discovery regarding the relationship between the eucalyptus trees and the sleepy lives of koalas. This episode features the surprising lives of koalas living in a pristine forest.
