Checkup time

Yangyang the dolphin is lifted out of a water tank at Yangzhou Ocean World in Yangzhou, Jiangsu province, on Tuesday. It was given a gastroscopy — an examination of its stomach. Trainers found plastic residue in the animal’s mouth and feared Yangyang might have eaten something by mistake. The checkup showed a 1 centimeter object in Yangyang’s stomach that is likely to be excreted naturally. Doctors have asked tourists not to feed the animals.
