Giant pandas are easily recognizable by their distinctive black spots surrounding their eyes, but do you know why they have them? These distinctive dark spots are the result of millions of years of evolution and play a crucial role in the animal's survival. The black spots around a panda's eyes serve to protect it from ultraviolet light, deter predators, and distinguish it from other members of the same species.
Protection from ultraviolet light
Pandas' small eyes, almost devoid of white parts, are extremely sensitive to bright light. The black spots absorb UV rays and increase the surface area of the fur that protects the eyes, similar to natural sunglasses, which helps reduce sensitivity to sunlight.
Intimidating function against predators
Although large predators are now rare in their habitat, pandas traditionally have to defend themselves from animals like tigers. The spots around their eyes can make them appear larger and therefore intimidating, acting as a visual deterrent.

Individual recognition
Each panda has a unique pattern of black spots around its eyes, similar to human fingerprints. This allows the animals to recognize each other and contributes to social interactions within the species.
Progressive development of spots
At birth, the pups are free of black spots, which begin to appear after a few days. By day 15, the spots appear, and they reach their adult form within a little over a month and a half.
Other curiosities
Polar bears, despite being related to pandas, lack black spots, but protect themselves with black skin beneath their fur and hollow, light-reflecting fur. Some pandas with genetic mutations, such as albinism, may lack the characteristic black spots. Other animals, such as the black-footed ferret, also have dark spots around their eyes, used for similar purposes.
