Seal Pet

Life history
Reproduction
Males of some species, including Elephant seals, South American Sea Lions, and Northern Fur Seals) aggressively defend groups of specific females, referred to as harems. Males of other species, including most sea lions and Brown Fur Seals) defend territories on reproductive rookeries while females move freely between them. Occasionally violent competition for females or territories is an integral part of male breeding strategy among most pinnipeds. Otariids, which are generally more land-adapted, form major aggregations in the summer months on beaches or rocky outcrops. Consequently, their reproductive behavior is easier to observe and relatively well-studied. Walruses and many phocids, on the other hand, form smaller aggregations, often in remote locations or on ice, and copulate in the water. Their reproductive behavior is less well known.
