An otter at a zoo in eastern China retrieved a phone dropped into its enclosure pool by a tourist.

Video filmed in the city of Shanghai on October 7 shows a keeper named Shen Yanhong introducing a 4-year-old otter and demonstrating his behaviours to the tourists at Shanghai Wild Animal Park.

However, a tourist who was filming the clip suddenly dropped their phone and the otter dived into the water to pick it up immediately.

Shen said the otter named "You Tiao" was trained to pick up rubbish, so he thought the phone was rubbish and picked it up.

10月7日，上海野生动物园的小爪水獭展区在进行水獭科普讲解和行为展示时，一名游客不小心将手机掉入水中，水獭第一时间捡回了水里的手机，手机里的相机正好记录了这一幕。对此，上海野生动物园保育员沈燕红称，水獭平时会做一些“捡拾垃圾”的行为训练，所以手机掉到水里时它的第一反应是有垃圾，于是把手机给捡回来了。（视频由上海台提供）
