A wallaby is a marsupial, closely related to kangaroos, that is native to Australia and nearby islands. These small to medium-sized animals belong to the family Macropodidae, meaning "big foot." Wallabies have several species that differ in size, habitat, and behavior, but they generally have strong hind legs for hopping, a long tail for balance, and a pouch for carrying their young. They are herbivorous, primarily grazing on grasses, leaves, and shoots. Wallabies are social creatures, often found in small groups, and they play an essential role in their ecosystems by helping to disperse seeds and graze on vegetation.
