Southern elephant seal diving abilities Southern elephant seals can dive from 400 to 1,000 meters (1,300 to 3,300 feet) for up to 20 minutes at time. The deepest recorded dive doubled that average, reaching a little over 2,100 meters (6,890 feet) deep. To stay underwater so long,...
Male southern elephant seals can be as long as 6 meters and can reach up to 4,000 kilograms in weight, while female seals or cows measure around 3 meters and weigh 900 kilograms on average. The northern elephant seal displays a yellowish or gray-brown color, while the southern elephant sea...
Elephant seals are wide-ranging, pelagic, deep-diving (average of 400–600 m) predators that typically travel to open waters and continental shelf edges thousands of kilometers from their land breeding colonies. We report a less common pattern of foraging in the shallow waters of a continental ...

All data shown have been processed as described in Methods. Full size image While much remains to be learned about northern elephant seals, the long-term biologging data set that began during the TOPP program has contributed greatly to our understanding of elephant seal behavior, physiology, and...
During its 85 day trip, the seal encounters two well-defined mesoscale features: a cyclonic eddy and a meander located at the easternmost tip of the standing meander area (Fig.2). The cyclonic eddy has a size of∼150 km and is located north of an anticyclonic one, creating a dipo...
The southern elephant seal is a deep-diving, wide-ranging marine predator spe- cies20 that forages in either one of three main habitats: the Antarctic continental shelf, the Kerguelen Plateau or deep open water regions21. Antarctic shelf waters provide prime habitat for both sexes, but females...
In this regard, the southern elephant seal (SES hereafter, Mirounga leonina) represents a particularly interesting model. It is the largest phocid species whose pups nurse for only about 21 days before undergoing a PWF lasting 5–6 weeks [51]. There are few data on the behaviour of weaned ...
