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.

Researchers are exposing the secrets of the world’s southernmost mammal, the Weddell seal. These seals, found in Antarctica’s Erebus Bay, live in rapidly changing environments. They can weigh ...
Characteristic fauna of the sea include the Weddell seal and killer whales, humpback whales, minke whales, leopard seals, and crabeater seals are frequently seen during Weddell Sea voyages. The Adélie penguin is the dominant penguin species in this remote area because of their adaptation to the harsh environment.
Weddell in 1828. James Weddell FRSE (24 August 1787 – 9 September 1834) was a British sailor, navigator and seal hunter who in February 1823 sailed to latitude of 74° 15′ S—a record 7.69 degrees or 532 statute miles south of the Antarctic Circle—and into a region of the Southern Ocean that later became 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 Weddell seal has perhaps the most extensive vocal repertoire, producing both airborne and underwater sounds. Trilling, gluping, chirping, chugging and knocking are some examples of the calls produced underwater. When warning other seals, the calls may be pronounced by "prefixes" and "suffixes". [116]
Haul-out sites of Weddell seals are not necessarily geographically distinct from one another and vary due to physical factors (i.e. food availability) and biological factors (i.e. age). [7] Weddell seals are high latitude Antarctic inhabitants, allowing them to haul-out onto ice as adults year round for foraging. [7]
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 ...
