Zookeeper Kim Jong-kap touches the mouth of 22-year-old Asian elephant Koshik at South Korea's largest amusement park Everland in Yongin, about 50 km south of Seoul. The Asian elephant named Koshik can imitate human speech, saying words in Korean that can be understood by speakers of the language, researchers from the University of Vienna say. Koshik was the only elephant living at the Everland Zoo in South Korea for about five years in his youth, with only people for company during an important phase for bonding and development.KIM HONG-JI/Reuters
