Why pandas have dark circles under their eyes

According to the Xingdao daily, Carol, a professor at the University of California Davis who led the research, said that a long-standing problem in the biological community is how to understand the black and white color of giant pandas. This is not easy to answer, because other mammals do not look like this, so it is difficult to explain by analogy. Researchers from the University and California State University at Long Beach divided the body of the giant panda into different regions according to the color of its fur, and compared it with 195 carnivorous animals such as dogs, cats and bears and 39 subspecies of bears. To find relevance and determine its function.

Researchers found that the face, neck, belly and buttocks of giant pandas are white Because it can help them hide in their snowy habitat; The reason why the limbs are black is that it can help them hide themselves in the shadow. Researchers believe that the reason why giant pandas grow like this is that they have weak digestive ability and can only eat bamboo instead of more plants. They can't store excess fat in winter to hibernate like some bears. They must be active all year round and travel long distances to find food. Their habitat changes greatly, from snow mountains to tropical forests.
