All female kangaroos have a pouch with four nipples. "Cubs" or kangaroos grow up in the pouch until they can survive in the outside world.
Kangaroos belong to Kangaroo family, which refers to Kangaroo suborder, marsupials, mammals, chordates and animal kingdom. They are famous mammals in Australia and occupy an important ecological position in Australia. Kangaroos have short forelimbs and developed hind limbs. They often lift their forelimbs and jump on the ground with their hind legs instead of running. Kangaroos are generally 2.6 meters tall and weigh about 80 kilograms.
Kangaroo pictures are often used as national symbols of Australia, such as green triangle kangaroos used to represent Australian manufacturing. Kangaroos often appear in expressway, which means kangaroos often appear nearby, especially when driving at night. Kangaroos have poor eyesight, are curious about the light and will jump out to "see the truth". However, due to their high reproductive rate, even if they are killed accidentally, they will not be responsible, and there will be special people to take away the bodies of kangaroos.
