Mirounga leonina
Largest of the 'true' seals (that is to say, earless and hind flippers cannot be turned forward. Family Phocidae). Mature males average weights of up to 3500kg, females 500kg and pups are born around the 40kg mark. Males are unmistakeable with a large inflatable proboscis. These animals have no under fur but rely on a thick layer of blubber for insulation from the cold. seen on land during mating, giving birth and a most remarkable moulting process. (see notes)
Found around most sub Antarctic zones where there is suitable land to pull up on such as beaches, and flat coastal areas. The southern Pacific population took a nose dive after intense harvesting for blubber oil. Since the ban on hunting in 1830, populations have stabilized in this region but not grown hugely whereas in the Southern Atlantic, this species is doing well. These images were taken on Maquarie Island in Australian territory.
There are so many notes that could be added to this fascinating species. However one of the most interesting is the incredible moult these animals go through each year. For 4-6 weeks of the year they are land bound as they slough off their hair and skin in large patches. The cost in energy is immense as they are forced to fast during this period and basically regrow their skin. Images show, a battle scared young male, male, female, pup and pup with a male for size comparison.

Hi Guys, saw these ones on Maquari Island in the Sub Antarctic. Yes Josh, they are brutal with each other.
He's one brutal looking guy!
