Southern Elephant Seals (Mirounga leonina) are named after the huge trunk-like nose on the males and make sounds that sound like a gurgling drain. They are the largest non-whale predators – males weigh up to three tonnes and adult females between 300-900 kg. Elephant Seals spend most of their lives at sea and are prodigious divers, reaching depths of 2 kilometres and staying down for two hours. They come to land to breed (October-November) and to moult (January to April). This old male Southern Elephant seal was dozing on the beach at St Andrew's Bay, South Georgia. His bulbous, trunk-like nose is huge and his head and neck are covered with scars from fighting with other males for dominance earlier in the season. There are King Penguins in the background, and their moulted feathers litter the sand.
