Why do giant pandas have dark circles under their eyes, and why do giant pandas have 2 dark circles?

On the one hand, it is to adapt to the cold environment. Pandas inhabit high altitudes, often have long winters and a lot of snowfall, so it is so cold that white fur alone is not enough. In the process of evolution, in order to protect the visual organs, there is a "dark circle" that everyone loves, and similarly, in order to ensure that the chewing organs, olfactory organs, auditory organs and locomotor organs are not frostbitten, their coat color changes from light to dark, absorbing sunlight, just as people often wear dark clothes in winter, with dark earmuffs, gloves, and knee pads, which plays a role in reducing heat loss.

On the other hand, for the sake of defense and self-protection. The dark circles of the panda are like wearing a pair of dark sunglasses, and it looks like a pair of big round eyes from a distance, and the real eyeballs of the panda are very small, due to the long-term living in the secluded environment of the deep mountains, forests and seas, the visual range is limited, and the cool "dark circles" outside the eyes make the eyes look magnified countless times, if other animals look at it, they can't see the size of the real eyeballs, which is enough to make the enemy "think twice". But this limited visual range and short-sighted ability allows pandas to be active after nightfall, because they have cat-like eyes that can adjust to changes in light at night.

The black and white tones of the whole body, shuttling through the snowy environment of the alpine forest, adapt to the natural environment, and their clothing becomes a protective color.

During the long winter months, when food for all animals is scarce, and the ferocious beasts are more difficult to prey, threatening the animals of their neighbors, and the panda is much less threatened by such clothing. This protective color, coupled with the coarser fur of the pandas, the thicker layer of hair, and the special oil on the surface of the fur, make the pandas dress with a thermal insulation effect, and can sleep comfortably in the snow at night.
