Except for koalas, all other bears have tails, but the bear's tail hardly grows up in the process of growth and development. Therefore, when the bear is young, the tail appears relatively large and easy to see. However, the bear becomes larger in adulthood, but the tail does not grow up. Moreover, the bear does not move its tail very much. It is generally holding its ass, so it is difficult to observe.
