What is a "great grey kangaroo"?

The great grey kangaroo, also known as the eastern grey kangaroo, is a large marsupial that is native to Australia. It is the second largest kangaroo species, with males growing up to 1.8 meters in length, excluding their long tail, and weighing over 60 kg. They are known for their distinctive grey fur, which provides excellent camouflage in their natural habitat. Great grey kangaroos are well-adapted for hopping, with powerful hind legs and a long, muscular tail used for balance. They are herbivores, primarily feeding on grasses and other vegetation, and are known for their efficient digestive system that allows them to extract maximum nutrition from their plant-based diet. Great grey kangaroos are social animals, often forming loose groups known as "mobs" or "troops," and are known for their impressive hopping abilities and graceful movements. They are iconic symbols of Australia and are found in a variety of habitats, including forests, woodlands, and grasslands.
