Male elephant seals have a simple breeding biology: they struggle to mate with as many females as possible. Their main mating tactic is to get control of a female harem, and mate multiple times with each harem female (which is called polygyny). That usually means fighting against other males.
In October 2022, during elephant seals peak of the breeding season at Sea Lion Island (Falkland Islands), male BAM decided to challenge DOZ, the harem holder of a big harem. DOZ was not very happy about this, he won the fight and kept control of his harem; after the fight he carried out various matings. This is something that males often do. If they take over a harem, or defeat a challenger, they mate with as many females as possible. In the case of challengers taking over a harem, this is probably related to sperm competition, i.e., they try to fertilize females that already copulated with the previous harem holder. In the case of harem holders keeping their harem, this can be a behavioral tactics to re-affirm the control over the harem females.
