Elephant seals return to their island of birth to breed and moult, but the rest of the year they range widely, often visiting the continents adjoining the Southern Ocean, the pack-ice region and the Antarctic continent.
The two fur seals found on Marion Island are similar in appearance (especially the females and pups), but the males can be told apart by the fl crest and ginger-brown belly of the Sub-Antarctic compared to the more uniform grey-brown of the Antarctic Fur seal.
Breeding sites of the Sub-Antarctic Fur seals are mainly confined to the exposed west side of the island, while breeders of the smaller Antarctic fur seal population are found on the southern coast.
