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.
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 ...
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]
In the sea, leopard seals, sea lions and killer whales are all predators of the gentoo. On land, no predators of full-grown, healthy gentoo penguins exist. Skuas and giant petrels regularly kill many chicks and steal eggs; petrels kill injured and sick adult gentoos.
According to DOC, Owha is "the longest tracked leopard seal in the world". [1] In order to track her movements, and the movements of other leopard seals, DOC helped modify a phone app used to report Hector's dolphin sightings so that it can accept reports of other marine species. [14]
Emperor penguin attacked by a leopard seal Giant petrel and emperor penguin chicks. The emperor penguin's predators include birds and aquatic mammals. Southern giant petrels (Macronectes giganteus) are the predominant land predator of chicks, responsible for over one-third of chick deaths in some colonies; they also scavenge dead penguins.
Fossil in Peru. The fossils of A. longirostris have been discovered in the Pisco Formation of Peru and the Bahía Inglesa Formation of Chile. [1] When it was first described in 1981, it was thought to have been closely related to the lobodontine seals which includes the modern-day leopard seal (Hydrurga leptonyx), the crabeater seal (Lobodon carcinophaga), the Weddell seal (Leptonychotes ...
Indeed, first-year mortality is exceedingly high, possibly reaching 80%, and up to 78% of crabeaters that survive through their first year have injuries and scars from leopard seal attacks. [1] Long scars and sets of parallel scars, visible on the otherwise pale and relatively unmarked pelage of crabeaters, are present on nearly all young seals.
