An aquarium in South China's Guangxi Zhuang Autonomous Region said it's been keeping a close eye on a 200-kilogram shark that just had successful surgery in a sensitive spot.
The resident nurse shark at Underwater World in the provincial capital of Nanning had apparently pushed too hard to pass an undigested fish in September, resulting in a prolapsed anus, park employees said.
Local veterinarians were finally called in on Thursday morning for the tricky procedure on the 3-meter shark they had to perform while keeping it submerged.
"The most difficult part about the surgery was doing it underwater," said Wei Jinni, an employee at the park.
Two vets and six technicians worked in waist-deep water as the sedated shark lay in a sling that served as an operating table, video showed.
"We hadn't done anything like this before at the aquarium," said Wei.
The shark, which has been at the park since 2009, is recovering and being closely monitored, she added.
