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). Male Southern Elephant Seals engage in vicious fights with each other to establish dominance and to establish a harem of females, with whom they mate after the females give birth. This exhausted, battle-scarred male Elephant Seal was sleeping on his back on the stony beach in Fortuna Bay, on the subantarctic island of South Georgia, breathing and snoring through on snotty nostril.
