Male northern elephant seals (Mirounga angustirostris) compete with one another for territories along the beach and defend these territories throughout the breeding season. The males that win the male-male competitions defend the "best" territories and have access to females that stay in that territory of the beach. The females land on the beach during mating season, chose which territory of the beach to join, and then disproportionately breed with the male that defends that area of ...
