A video of a bear at a Chinese zoo has gone viral in recent days, as debate rages over whether the animal is in fact a human wearing a costume.
Originally released last Friday, the video shows a bear standing on its hind legs inside its enclosure at Hangzhou Zoo in Zhejiang province as visitors looked on.
Due to the bear's humanlike stance and folds of loose skin on its lower back, people online have questioned the animal's authenticity.
The zoo responded in a light-hearted manner, with Reuters reporting that it had posted a statement on WeChat role-playing as the bear.
“Yesterday, after I got off work, I received a call from the director, asking me if I was lazy and did not go to work, and had hired a two-legged animal to replace me,” it read.
“Some people think I stand like a person. It seems you don’t understand me very well.”
Zookeepers told the local newspaper Hangzhou Daily that the sun bear, which comes from Malaysia, is smaller than other bears and has a different appearance.
Sun bears, which are the smallest bears in the world, are only about the size of a large dog.
It added that local temperatures, which have reached almost 34°C in recent days, would make any bear costume-wearing human extremely uncomfortable.

What is graphene?
Graphene is a single layer of carbon atoms arranged like honeycomb.
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.
At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.
It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.
But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.

Types of policy
Term life insurance: this is the cheapest and most-popular form of life cover. You pay a regular monthly premium for a pre-agreed period, typically anything between five and 25 years, or possibly longer. If you die within that time, the policy will pay a cash lump sum, which is typically tax-free even outside the UAE. If you die after the policy ends, you do not get anything in return. There is no cash-in value at any time. Once you stop paying premiums, cover stops.
Whole-of-life insurance: as its name suggests, this type of life cover is designed to run for the rest of your life. You pay regular monthly premiums and in return, get a guaranteed cash lump sum whenever you die. As a result, premiums are typically much higher than one term life insurance, although they do not usually increase with age. In some cases, you have to keep up premiums for as long as you live, although there may be a cut-off period, say, at age 80 but it can go as high as 95. There are penalties if you don’t last the course and you may get a lot less than you paid in.
Critical illness cover: this pays a cash lump sum if you suffer from a serious illness such as cancer, heart disease or stroke. Some policies cover as many as 50 different illnesses, although cancer triggers by far the most claims. The payout is designed to cover major financial responsibilities such as a mortgage or children’s education fees if you fall ill and are unable to work. It is cost effective to combine it with life insurance, with the policy paying out once if you either die or suffer a serious illness.
Income protection: this pays a replacement income if you fall ill and are unable to continue working. On the best policies, this will continue either until you recover, or reach retirement age. Unlike critical illness cover, policies will typically pay out for stress and musculoskeletal problems such as back trouble.
