The white spots behind a tiger's ears are one of the most curious details of its appearance. Scientists call them "false eyes." This feature is found in various animals and serves as a powerful tool for protection: the contrasting circles create the illusion of a gaze and deter potential enemies.
When a tiger lowers its head or rests, the white markings become particularly noticeable. From behind, it seems as if someone is watching the approaching predator. This deception often saves the tiger's life — an opponent prefers not to attack, thinking that it has been noticed.
This natural trick has proven so effective that humans have adopted it as well. In the mangrove forest area of Sundarbans on the border of India and Bangladesh, where Bengal tigers live, locals wear masks with images of eyes on the back of their heads when going out for firewood or fishing. It is believed that a tiger will not attack if it feels that it is being watched. This technique is based on an understanding of predator behavior and truly helps avoid attacks.
But the function of the white spots is not limited to protection. They also serve as an important means of communication. The contrasting markings help tiger cubs keep track of their mother in dense underbrush and low light. Additionally, a tiger's ears are mobile: their position can indicate the animal's mood — alertness, fear, or aggression. The white spots enhance these signals, making them more noticeable to other tigers.
This feature has developed over millions of years of natural selection. Animals with more expressive "false eyes" survived better and passed the trait on to their offspring. Combined with their camouflage coloring — orange with black stripes — the white spots have become an ideal element of the evolutionary strategy: they provide protection, aid communication, and make the tiger almost invisible in the eyes of its prey.
