What is kangaroo's bag?

Kangaroo's pocket is a nursery bag, and newborn kangaroos will stay in the kangaroo pocket until they grow up.

Zoologists have confirmed that kangaroos are typical representatives of marsupials. Marsupials are immature animals, belonging to premature fetuses, and need to develop in breast-feeding bags. The female kangaroo has four nipples, two with high fat and two with low fat. Generally, female kangaroos give birth to 3-4 cubs per litter. Kangaroos have to climb into the bag through the cloakroom and eat low-fat milk after birth, which determines that only two kangaroos can survive in each fetus.

Kangaroos are very small at birth, only about 1 peanut. Adult kangaroos are about 1.6 meters tall and can weigh up to 50 kilograms. Kangaroos jump with their lower limbs and run very fast, with a speed of more than 50 kilometers per hour.

Kangaroos have a "multifunctional" tail, which plays a very important role. When resting, you can support yourself on the ground and balance your body with your lower limbs. Tail is an important balance tool in running, and kangaroo tail is also an important weapon in attack and defense. Others say that kangaroo is a brave animal. It only goes forward, not backward.

Generally speaking, large kangaroos are highly adaptable to human development in Australia; In contrast, many of their little relatives face a greater threat to their survival, and the number is not large.

At present, there is no large-scale kangaroo breeding industry, but wild kangaroos will be hunted and made into edible meat, and this industry is also controversial.

The origin of Kangaroo's English name "Kangaroo" is said to have originated from an Australian aborigine, Guugu Yimidhirr, which means "gangurru", which is due to a misunderstanding.

James cook, England, made its maiden voyage, and hit the rocks on the Great Barrier Reef in the northeast of Australia in June, 770, and finally repaired the ship on the bank of Endeavour River (now the port of Cook Town). For seven weeks, joseph banks, a botanist, accidentally discovered a strange animal, so he asked Guguyi Mishe, a local Australian aborigine. Because the aborigines don't know English, they replied that they don't know (gangurru).

Banks mistook gangurru for the English name of Kangaroo. This legend was confirmed by John B. Haviland, a linguist, in his research on the ancient Amish people in 1970s. Kangaroo's local name is ganguro, which means "I don't know".

Kangaroo is a symbol of Australia, which appears in the national emblem of Australia and some Australian currency patterns. Many Australian organizations, such as Qantas, also use kangaroos as their symbols. Australian military vehicles and ships are often painted with kangaroo signs when performing overseas missions.
