I do not know how many people have remembered a text learned in high school - "the mystery of animal games", which tells the story of why animals play games, and what they can bring the benefits of the game. And the animal kingdom, in addition to the game, more of a fight with each other, the same as the human world, and even more intense.
Battle is the innate nature of life, and the struggle usually has a certain purpose. Wildlife photographer Bloom Steve has taken photos of a group of wild animals fighting each other. Everyone in the process of viewing may wish to think about, they are in the end is in the game or fight.
Animal fighting sites simply in order to snatch, courtship, play, maybe the mood is not so clear will fight. The human characteristic of these animals is more varied and complex.
