海鬣蜥的戰鬥(Marine Iguana Combat)

繁殖季節開始，是驗收雄性海鬣蜥求偶打鬥能力的時候。強壯的雄性會彼此打鬥，除了少數以撕咬方式攻擊外，大多數選擇相對平和的角力比賽！用頭部特化前額鱗一帶互相頂住對方，可避免海鬣蜥彼此因打鬥太過激烈，而受傷以致失去生命。這是長久演化的成果呢！

At the start of the breeding season, male marine iguanas fight each other for the chance to mate. It is the stronger males that do battle. In only a few cases, will male iguanas violently bite each other, with most competitions decided by “wrestling”. They use specialized bony plates on their heads which can interlock. In this way, they avoid serious injury or death. This combat is the result of a long period of behavioral evolution!
