The diet of southern elephant seals (Mirounga leonina) from Heard Island

Stomach contents were lavaged from 76 M. leonina. Eighty-six percent of stomachs contained cephalopods of 17 species. Sixty-six percent of stomachs contained fish remains. The diet of adults differed from that of juveniles, particularly pups in their first year. Smaller seals ate smaller squid. The species and size of cephalopods eaten by these seals are similar to those of other Southern Ocean predators, particularly some beaked whales. -from Author
