The attack took place on Saturday night at Lake Naivasha, about 58 miles from the Kenyan capital Nairobi. Chang Ming Chuang, 65, took photos of the hippopotamus on the shores of the lake with a colleague as the animal attacked.
Chuang was taken to the Naivasha County Hospital where he was pronounced dead. Chuang's colleague Wu Peng Te, 62, survived the attack with mild bruising and recovered at the Naivasha Sopa Resort, the Wildlife Service said. KWS tracks the hippopotamus.
