Kangaroos are Australia's national treasure. They generally just move forward and not backward, so people also use kangaroos as a metaphor for their courage to move forward. Kangaroos are gifted boxers, which are related to their genetics and body structure.

Its whole body muscles are stronger than those of fitness people, and its upper limbs are very flexible. The stout tail not only balances and supports the body, but can also be used for attack. Their attack is very powerful, and it is said that it can break a tree with one tail.

When the kangaroo stood up, it was two meters tall and weighed more than 300 kilograms. Kangaroos are also kind by nature. As long as they are not provoked, they will not easily attack humans.

Most kangaroo fights are caused by male kangaroos fighting for the right to mate with females within the population. Moreover, they have strong territorial rights mind, so don't approach them easily.

Such a ferocious kangaroo is also liked by many people. Australia has kangaroo boxing competition. In the local area, many people have raised wallabies. With talent and acquired training, it is a good boxer.

Kangaroos are herbivores and mainly eat grass. In the process of eating, they will use their powerful hind legs to jump to the location of the food, and then land on their forelegs to bend their bodies, thus gnawing on the grass on the ground and occasionally on shrubs、young leaves and fruits.

Kangaroos also feed on fungi. In the process of living, kangaroos will use caves, rock crevices, trees, etc. as shelters, and such environments are prone to fungi with high humidity. Therefore, kangaroos will eat fungi and other foods, but they will use their noses to determine whether the fungi are poisonous before eating.

Kangaroos living in zoos mainly eat vegetables, hay, fruits, etc. These foods are rich in vitamins and amino acids, which can provide kangaroos with sufficient nutrients, but wallabies often feed on breast milk or fresh milk. It uses its forelimbs to grab objects while eating.

Kangaroos usually live in groups, sometimes as many as hundreds. But there are also smaller species of kangaroos that live alone. Most of them are active at night, but some are active in the morning or evening.

Kangaroos are the highest and furthest jumping mammals. Jumping is a strange gait for a large mammal, but it's not the only way kangaroos walk. Kangaroos don't just hop, they crawl on four feet when moving slowly, but a pair of forelimbs and a pair of hindlimbs move together, not in a cross.
