7か月齢のホッキョクグマ、じゃれて負傷し死亡

The death of a seven-month old polar bear at the Ouwehands Zoo in Rhenen was likely caused by rough play with her older, larger sister, the zoo said on Wednesday. The conclusion was made based on autopsy results, which also showed that the young male cub had a respiratory infection. Yura's twin brother, Yuka, was not harmed. While Yura weighed roughly 65 kilograms, his five-year-old sister weighs in at around 300 kilograms. "Sura and the boy played together regularly, always under the watchful eye of their mother and grandmother," the zoo said.
