Understanding the ontogeny of diving behaviour in marine megafauna is crucial due to its influence on foraging success, energy budgets, and mortality. We compared the ontogeny of diving behaviour in two closely related species—northern elephant seals ( Mirounga angustirostris, n = 4) and southern el...
