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 hooded seal or bladdernose seal (Cystophora cristata) is a large phocid found only in the central and western North Atlantic, ranging from Svalbard in the east to the Gulf of St. Lawrence in the west. The seals are typically silver-grey or white in color, with black spots that vary in size covering most of the body. [3]
Seal meat is the flesh, including the blubber and organs, of seals used as food for humans or other animals. It is prepared in numerous ways, often being hung and dried before consumption. It is prepared in numerous ways, often being hung and dried before consumption.
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]
The ribbon seal dives to depths of up to 200 m in search of food; it is solitary and forms no herds. Ribbon seals located in the Bering Sea consume pollock, eelpout, and arctic cod. [ 13 ] Adult seals have relatively weak and smooth canines because their food does not need to be viciously torn.
Seal hunting stopped in Australia in 1923, and their population is still recovering, causing increasing friction with South Australian fishermen as their range expands. [22] Breeding and haul-out sites are protected by law. South African fur seals have a very robust and healthy population. Harvesting of seals was outlawed in South Africa in 1990.

These projects focused on southern elephant seals because they are deep divers as well as a major predator in the Southern Ocean in terms of their population size and food consumption. As predators of the upper levels of the food-web, their foraging success and population dynamics impart valuable information about productivity at different ...
