Researchers with a nature reserve in China's Sichuan province said two wild pandas recently captured on the reserve's infrared cameras are suspected to be a pair of twins.
In a clip filmed on October 21, two wild giant pandas of similar size were seen playing with each other on a mountain in Wolong National Nature Reserve, Xinhua news agency reported.
Experts said it was the first time the reserve observed a pair of pandas living together during non-mating season.
Wild pandas are solitary animals and live with their mothers before the age of two. The pandas are possibly twins brought up together, experts said.
The reserve has started collecting DNA near the site where the pandas appeared in order to back up their suspicions.
