Male giraffes fight each other by 'necking'! They push their long necks against each other, bending and twisting them in order to win the fight by a show of strength. Many animals fight this way, including snakes, insects and crabs. Competing in this way allows animals to find out who's boss while protecting themselves from injury. The strongest wins and the loser just has to go away.
