The leopard seal is the second largest species of seal in the Antarctic. It is most common in the southern hemishpere along the coast of Antarctica and on most sub-antarctic islands,but can also be found on the coast of Australia, Tasmania, South Africa, New Zealand, Lord Howe Island, Terra del fuego, the Cook Islands, and the Atlantic coast of South America. It can live twenty-six years, possibly more. Orcas and large sharks are the only natural predators of leopard seals.
The leopard seal is larger and muscular, with a dark grey back and light grey on its stomach. It's throat is whitish with the black spots that give the seal it's common name. Females are generally slightly larger then the maleson average. The bulls are generally 2.5- 3.2m (8.2-10.5 ft) and weigh between 200 and 460 kg (440 and 1,000 lb., while cows are between 2.4 and 3.4m (7.9 and 11.2 ft) in length and weigh between 225 and 600kg (500 and 1,300 lb). The Leopard Seal is highly evolved for it's role as apex predator. Although it is a true seal and swims with it's hind limbs, it has power.
