The most common land mammal in Australia is the kangaroo. These marsupials are iconic symbols of the Australian wildlife and can be found in various species across the continent. Kangaroos are known for their distinctive hopping movement, powerful hind legs, and long tails, which aid in balance. They primarily inhabit forests, grasslands, and savannas. Their social behavior typically includes living in groups called mobs, providing safety in numbers. Kangaroos are herbivores and play an essential role in the ecosystem, contributing to the maintenance of grasslands by grazing.
