This simultaneous collection of behavioural and environmental data, spanning more than ten years, has enabled researchers to study the impact of climate change on southern elephant seals and the Antarctic ecosystem. This data provides information on how the Southern Ocean is changing in relation to climate change as well as how these species ...
The northern elephant seal (Mirounga angustirostris) is one of two species of elephant seal (the other is the southern elephant seal). It is a member of the family Phocidae (true seals ). Elephant seals derive their name from their great size and from the male's large proboscis , which is used in making extraordinarily loud roaring noises ...
Elephant seals or sea elephants are very large, oceangoing earless seals in the genus Mirounga.Both species, the northern elephant seal (M. angustirostris) and the southern elephant seal (M. leonina), were hunted to the brink of extinction for lamp oil by the end of the 19th century, but their numbers have since recovered.
Crabeater seals can raise their heads and arch their backs while on ice, and they are able to move quickly if not subject to overheating. Crabeater seals exhibit scarring either from leopard seal attacks around the flippers or, for males, during the breeding season while fighting for mates around the throat and jaw. [3]
CCAS forbids the killing or capture of Antarctic seals except in specific circumstances. [3] The contracting parties of CCAS may decide the standards for killing and capture as dynamics of the seal populations change, and these decisions should be "based upon the best scientific and technical evidence available".
These seals spend two-thirds of their time at sea. Monk seals spend much of their time foraging in deeper water outside of shallow lagoon reefs at sub-photic depths of 300 metres (160 fathoms) or more. [20] [21] Hawaiian monk seals breed and haul-out on sand, corals, and volcanic rock; sandy beaches are more commonly used for pupping. [13]
Harp seal births are rapid, with recorded lengths as short as 15 seconds in duration. [19] In order to cope with the shock of a rapid change in environmental temperature and undeveloped blubber layers, the pup relies on solar heating, and behavioral responses such as shivering or seeking warmth in the shade or even water. [19]
The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic ...
