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 post-molting juveniles, males and females, leave Península Valdés and head SW they cross the deep Atlantic basin reaching the waters that surround South Georgia. Months later, they return to the Patagonian coasts traveling distances of over 10,000 km.
