Pandas Giant pandas are black-and-white Chinese bears that are on the verge of extinction. These large, cuddly-looking mammals have a big head, a heavy body, rounded ears, and a short tail. The Chinese people call the panda "Da xiong mao," which means "giant bear cat" in Chinese. The panda is a symbol of peace in China. This bear is quite different from other bears. It has unusual cat-like eyes, and its front paws have an opposable "thumb." Female pandas are called sows, males are called boars, and the young are called cubs. EYES Most bears' eyes have round pupils. The exception is the giant panda, whose pupils are vertical slits, like cats' eyes. These unusual eyes inspired the Chinese to call the panda the "giant cat bear." Pandas have very good eyesight. 参考资料：
