Along the beautiful coastline of California live the northern elephant seals (Mirounga angustirostris). When the females are ready, they emerge from the waters of the Pacific to nurse their newly-born youngsters, on land. They are then surveyed by several enormous bulls, one of whom comes to dominate during subsequent copulation-time, which starts about a month after the birth of their young. During copulation, the females utter a kind of snarl: this is thought to be a way of encouraging other males to intervene and compete among each other. How do we know this? Because on hand, in California, watching the struggle for ‘viable sperm’ is a mammalogist. Name? Burney Le Boeuf.
