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.
Seal meat hanging to dry on St. Lawrence Island. The study showed significant differences in nutritional composition from one seal to another. This may have been due to the highly varied age and size of the seals tested. In general, both the meat and blubber can be considered to be high quality food in terms of bioactive components and nutrients.
Diet: Lanternfish, as well as a narrow range of fish from the Scomberesocidae, Carangidae, Engraulidae, and Bathylagidae families, and cephalopods [12] LC 16,000 [12] New Zealand fur seal. A. forsteri (Lesson, 1828) Southern Australian and New Zealand coasts: Size: Male: 150–250 cm (59–98 in) long; 120–180 kg (265–397 lb)
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.
Seals typically swallow their food whole, and will rip apart prey that is too big. [97] [98] The leopard seal, a prolific predator of penguins, is known to violently shake its prey to death. [99] Complex serrations in the teeth of filter-feeding species, such as crabeater seals, allow water to leak out as they swallow their planktonic food. [85]
The leopard seal (Hydrurga leptonyx), also known as the sea leopard, is the second largest species of seal in the Antarctic, after the southern elephant seal. Its only natural predators are the killer whale and possibly the elephant seal. It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, birds and fish.
The diet of these seals is primarily composed of Salmonids in the summer with the diet of these seals remaining obscure throughout the remainder of the year. [14] This population has been recorded at around 400 individuals, though following particularly harsh winters in the 1970s, the population is thought to have dropped to as low as only 50 ...
