The kangaroo is only one bean when it is born, and it can reach 60,000 times of birth when it is adult.
The baby kangaroo was born on the ground, but the newly born baby kangaroo was similar to a small worm, only one large broad bean, and the eyes, ears and legs did not grow. Can such a small game climb into the pouch?
The wallaby really climbed into the pouch. It has no eyes and no legs. How do you see a baby pouch and how to climb?
After the baby kangaroo lays the pup, he bends his neck and rubs his stomach with his tongue. The baby kangaroo is a trace of the kangaroo squirrels, and he wriggles and crawls into the bag like a worm.
The kangaroo is still not fully developed. It is crawling up by the smell of the smell, or is the musk squirrel sucking the kangaroo up? These are still not clear, zoologists are still observing and studying.
