The Weddell seal [2] (Leptonychotes weddellii) is a relatively large and abundant true seal with a circumpolar distribution surrounding Antarctica.The Weddell seal was discovered and named in the 1820s during expeditions led by British sealing captain James Weddell to the area of the Southern Ocean now known as the Weddell Sea.

All lobodontine seals have circumpolar distributions surrounding Antarctica. They include both the world's most abundant seal (the crabeater seal) and the only predominantly mammal-eating seal (the leopard seal). While the Weddell seal prefers the shore-fast ice, the other species live primarily on and around the off-shore pack ice. Thus ...

The seals can live for as many as 30 years in the wild, while dealing with predators like orcas and larger leopard seals. They survive on fish, squid, and other smaller prey to survive.
The skull of the leopard seal. The leopard seal has a distinctively long and muscular body shape when compared to other seals. The overall length of adults is 2.4–3.5 m (7.9–11.5 ft) and their weight is in the range 200 to 600 kilograms (440 to 1,320 lb), making them the same length as the northern walrus but usually less than half the weight.
Other residents are facing an uncertain future too, including wave-washing killer whales. We discover that their favourite prey, Weddell seals, are now harder to reach, so instead they are resorting to targeting much more feisty prey, like crabeater seals and even leopard seals, an apex predator in its own right. This dramatic encounter has ...
Weddell seals (Leptonychotes weddellii) are the most southerly of Antarctic mammals. Six pinniped species inhabit Antarctica. The largest, the Southern elephant seal ( Mirounga leonina ), can reach up to 4,000 kilograms (8,818 lb) [ 4 ] and over 6 metres (20 ft) long, [ 29 ] while females of the smallest, the Antarctic fur seal ( Arctophoca ...
The polar bear is the most carnivorous of bears due to the arctic climate in which it lives, and shows a preference for eating seals. The giant panda is the most herbivorous bear and has evolved a number of adaptations, including a sixth "toe", specialized teeth, and strong jaw muscles, to allow it to feed nearly exclusively on bamboo , a tough ...
