Description. Weddell seals measure about 2.5–3.5 m (8 ft 2 in – 11 ft 6 in) long and weigh 400–600 kg (880–1,320 lb). [5][6] They are amongst the largest seals, with a rather bulky body and short fore flippers relative to their body length. [7] Males weigh less than females, usually about 500 kg (1,100 lb) or less.
Hauling out is a behaviour associated with pinnipeds (true seals, sea lions, fur seals and walruses) temporarily leaving the water. [1][2] Hauling-out typically occurs between periods of foraging activity. [1][3][4] Rather than remain in the water, pinnipeds haul out onto land or sea ice for reasons such as reproduction and rest. [4][2] Hauling ...
Weddell seal. The North-west White Island Antarctic Specially Protected Area comprises a 142 km 2 area of coastal shelf ice on the north-west side of White Island in the Ross Archipelago of Antarctica.The site has been designated an Antarctic Specially Protected Area (ASPA 137) because it supports an unusual small breeding population of Weddell seals, which is not only the most southerly known ...
Ribbon seal. The ribbon seal (Histriophoca fasciata) is a medium-sized pinniped from the true seal family (Phocidae). A seasonally ice-bound species, it is found in the Arctic and Subarctic regions of the North Pacific Ocean, notably in the Bering Sea and Sea of Okhotsk. It is distinguished by its striking coloration, with two wide white strips ...
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.
The crabeater seal (Lobodon carcinophaga), also known as the krill-eater seal, is a true seal with a circumpolar distribution around the coast of Antarctica. They are the only member of the genus Lobodon. They are medium- to large-sized (over 2 m in length), relatively slender and pale-colored, found primarily on the free-floating pack ice that ...
Antarctic Peninsula. Coordinates: 69°30′S 65°00′W. The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. Antarctic Peninsula map.
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 ...
