A 65-day-old tigon, the offspring of a male tiger and a female lion, is shown to the visitors in Yancheng Zoo, Changzhou, Jiangsu province on Feb. 28, 2012. With brown hair and the tiger-like figure, it can climb a tree swiftly better than a lion does and swim as a tiger. With low fertilization rate and survival ratio, there is no successful fertilization by men in China at present. (Photo/Xinhua)
