Bengal Tiger on the Hunt 🐅 Life in Color with David Attenborough | Netflix After School

Chital have only two types of color receptors in their eyes, compared to our three, which means that they are effectively blind to red and orange. So to the deer, the tiger isn't orange at all. This is how we see the world, and this is how the deer do. The tiger's orange coat, to them, is a muted shade of green. So it's nearly impossible for the deer to register. She creeps closer. The chital don't see her. The odds appear stacked in the tiger's favor. But the deer aren't entirely defenseless. They have help from an unusual ally, langur monkeys. They're known as the eyes of the forest, and their color vision is excellent. Their eyes, like ours, have three types of color receptors, and they can see orange. The langurs sounded the alarm before she could get close enough. If the langurs can easily spot her, why then is the tiger orange at all? Why isn't she green? That's because mammals are unable to develop green pigments. So it seems the next best solution for the tiger is to have orange fur, which appears green to her main prey.
