Antarctic fur seal (Arctocephalus gazella) male opening its mouth. The male is much larger than the female, reaching a length of up to 2 metres and a weight of 120 kilograms. The male's pelt is brown in colour, and includes a mane of shoulder fur. The external ears (pinnae) of a seal are also seen here. This seal ranges throughout the Southern Ocean that surrounds Antarctica, feeding mainly on krill in shallow waters at night. During the breeding season (from November to January) the males compete to secure a harem of females. Photographed on South Georgia.
