Kangaroos and wallabies are marsupials from the family Macropodidae, known for their powerful hind legs and long tails that help them hop and balance. Found mainly in Australia and nearby islands, they carry their young, called joeys, in a pouch. Kangaroos are generally larger and live in open grasslands, while wallabies are smaller and prefer forests or rocky areas. Both are herbivores, feeding on grasses and leaves.
