one the security camera is recording Mongolian, Chinese, impressive images in which you observe as a flock of sheep move together in a circle at the same time, as if it were a carousel.

Hundreds of sheep walked in a circle continuously for 14 days in the region of Mainland Mongoliain northern China, as reported on Nov. 16, People’s newspaper.

The strange behavior, captured by a CCTV camera shows the herd walking in the clockwise in an almost perfect circle.

​In the recordings it is observed how the flock circulates, while some sheep are left out of the rotation and others are motionless in the center of the circle. The most incredible thing, both for the farm owner and for the thousands of users who have already seen the clip, is that the mammals are said to be in perfect health. It has no visible condition beyond its attitude of walking on the same axis .

The People’s Daily reports it the sheep were healthy and that the cause of the strange behavior remains a mystery.

The owner of the herd, identified as Ms Miao, said the show was started by some sheep before the others joined, according to UK portal Metro. Although there are 34 pens in the ranch, only those of the pen number 13 they acted this way.

The experts of the British veterinary company Molecare farm veterinarians point out that the exact cause of such behavior is not known, but do not rule out that it is the effects of listeriosis, a bacterial disease.

This disease causes swelling on one side of the braincausing animals to walk in circles or suffer from paralysis on the affected side.

Zoological specialists explain that this mysterious dance is not that rare and this type of behavior can be too a defensive instinct.

What do they do it for? Animals do this movement create an impregnable fence to protect the most vulnerable of their pack from predators.

In the center of these circles are usually located females and their young then the males crowd around her in large numbers. Between this and the continuous movement they make it difficult for the attackers to attack, who generally give up and go in search of other prey that are easier to devour.

The fact that animals already have the protection of man and real fences like those seen in the video that accompanies this note, the sheep don’t seem to care if that’s the reason.
