Hunters of the Animal World

    In the cycle of life, predators always occupy an important position. They are killers. But they kill, only to 'kill' their hunger. In fact, the story of the animal kingdom is full of predators trying to catch prey, and the prey trying to outwit predators. It is the balance between the two that takes the drama of life forward.
