Kangaroos are herbivores and eat a variety of plants, and they are mostly active at night. The long hind legs are strong and powerful. Kangaroo jumps instead of running. It can jump up to 4 meters and as far as 13 meters. It can be said to be the highest and farthest jumping mammal. Most kangaroos live on the ground, using their tails for balance during jumps and as a fifth leg when they move slowly. The kangaroo's tail is thick, long and full of muscles. It can not only support the kangaroo's body when it is resting, but also help the kangaroo jump faster and further when it jumps. All female kangaroos have a front-open pouch, but males do not, and it is in this pouch that the "pups" or joeys are raised until they are ready to survive in the outside world.

The emu (ér miáo) is the only species of the Emu family. It is famous for its good running. It is a specialty of Australia and the second largest bird in the world, second only to the African ostrich. Therefore, it is also called the Australian ostrich. , its wings are more vestigial than those of African ostriches and American ostriches, and it has three toes. It is one of the oldest bird species in the world. It inhabits Australian forests and open areas and eats leaves and wild fruits. Emu pair up for life. Each clutch lays 7-10 dark green eggs with an egg length of 13cm. Builds a nest on the ground. The male incubates the eggs for about 60 days. The striped chicks quickly follow the adult birds after hatching. Special tracheal structures produce loud rumbling sounds during the breeding season. The emus is Australia's national bird.
