An eagle and a cobra hunt for their prey
An explanation of how the eyes of the eagle and the cobra help hunt their prey. The eagle can spot its prey from four miles away while the cobra's eyes have light sensing cells. The presenter attempts to approach the cobra without it unleashing a venomous strike, which can kill in minutes. He explains how light-sensitive cells in the cobra's eyes tire in minutes if what they are looking at does not move. He demonstrates this by kneeling in front of the cobra and staying very still. When he moves away from the cobra it attacks.
