The Eastern Grey Kangaroo is a marsupial found in southern and eastern Australia, with a population of several million. It is also known as the Great Grey Kangaroo and the Forester Kangaroo. Although a big Eastern Grey male typically masses around 66 kg.and stands almost 2 m tall, the scientific name, Macropus giganteus, is misleading, as the Red Kangaroo of the semi-arid inland is, at 85 kg, larger.
