Two heads are better than one. Eastern Grey Kangaroo

The eastern grey kangaroo is a marsupial found in southern and eastern Australia, with a population of several million. 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.
