There is a sex difference in the foraging behavior of adult elephant seals from Península Valdés. Most females travel long distances to the Atlantic basin, while males forage at or near the shelf break.

Juveniles would not show a sex-dependent strategy.

Some juveniles depart after the molt and remain on the continental shelf, feeding in the productive fronts that surround the Malvinas Islands, or explore other shallow waters such as the Chilean fiords (SE Pacific). After months at sea, they migrate back to the coasts of Argentine Patagonia.
