Females bear pups conceived during the previous season and mate again about six to seven days after giving birth.

Email Newsletter They are faster than humans when travelling across slippery rocks and amongst dense grasses. The Antarctic fur seal is a large, hardy, charismatic animal, well adapted to the severe climate in the Southern Ocean area and its surrounding sub-Antarctic islands.

This increase in visits has led to greater interaction between the local fauna and humans. In the South Georgia Islands, the mackerel icefish is the main prey. Where they go is not known or whether it is a dispersal or a directional migration, and some of the adult males and juveniles stay ashore for the whole year. The males feature a very dark brown color. Antarctic fur seals, Arctocephalus gazella (Peters, 1875), also known as Kerguelen and southern fur seals, like other fur seals, are distinguished by the presence of external ears and their ability to use their flippers to prop themselves up into a “standing” position. Weight: 90 to 215 kg, males being larger.. Damn cold. The area that Antarctic Fur Seals live in is referred to as the “Antarctic Convergence” - a zone of water between the frigid waters of the true Antarctic and the more temperate waters to the north. The new research combines analysis of the whiskers, which store a record of what they have eaten, with information about where the seals have been in the ocean, gleaned from miniature tracking devices attached to the seals' flippers. ... "But there's no getting around the fact that Antarctic fur seals are ridiculously cute [11] The current best estimate for South Georgia is 4.5-6.2 million animals and 46,834 at Bouvetøya. [33], Historically the species were decimated by the sealing industry for its fur and its population was driven close to extinction by the 19th century.

Each territorial male has an association with 1 to 27 females, the average being 15 females. Adults have very long vibrissae, particularly males, up to 35 to 50 cm. The nose does not extend much past the mouth, the external ears are long, prominent, and naked at the tip. The estimate for South Georgia is 4.5-6.2 million Antarctic fur seal and 46,834 at Bouvetøya.

It makes them look bigger and heavier from the front. The Antarctic fur seal is a solitary animal, except when breeding and molting. Anchoring in various spots around the region, the expedition offers the chance to hike, and... OTL29-21. other name: Kerguelen fur seal.

The largest colonies occur at Gough, Amsterdam and the Prince Edward Islands.

IUCN Conservation status: Least Concern.

According to the IUCN Red List, the total Antarctic fur seal population is 700,000-1,million mature individuals. [32] However, the abundance of adult females is estimated to have declined by some 30% between 2003 and 2012, and by 24% since 1984 to around 550,000. The coloring of the Antarctic Fur Seals allow them to be easily identified. [36] A 1997 study at South Georgia indicated that several thousand Antarctic fur seals were entangled in man-made debris such as discarded fishing line, nets, packing bands and anything that can form a collar. Males are larger than females. The Antarctic fur seal mostly lives in Subantarctic islands.[2].

[19] Juveniles may then spend several years at sea before returning to begin their breeding cycles.

"They are locked into that structure in a way that provides a really nice time series of data. Pups are weaned at about four months old. The breeding season lasts from mid-October through December. PLA31-21.

[43] Due to the remote location of where these injuries occur this can lead to complications in getting people to a physician with the relevant experience in treating exotic animal bites. Appearance: Antarctic Fur seals are usually brown in coloration with a slightly more light brown or grey tone in newly molted juveniles and females. iucn: Lower Risk—least concern.
Long whiskers Adult m length: female 1.3 m/4 ft; male 1.9 m/6 ft. weight: female 35 kg/80 lb; male 135 kg/300 lb The population of these seals on South Georgia Island is the world’s densest marine animal population.

The Antarctic fur seal (Arctocephalus gazella), is one of eight seals in the genus Arctocephalus, and one of nine fur seals in the subfamily Arctocephalinae. They’ll eat about a ton of krill a year.

Distribution and Numbers The breeding colonies of the Subantarctic fur seal, formerly known as the Amsterdam Island fur seal, are generally found on temperate islands in the South Atlantic and Indian Oceans, north of the Antarctic Polar Front.

The Antarctic fur seal is a large, hardy, charismatic animal, well adapted to the severe climate in the Southern Ocean area and its surrounding sub-Antarctic islands.

The isotopic compositions in the whiskers varies as a result of the seals eating different food types, and as the whiskers grow they reflect what the seals have been eating.

These seals appear to be solitary when foraging and migrating.

In this species the male and female are, amongst all mammals, the most different from each other. [7], Males are substantially larger than females.

Antarctic fur seals are one of the better-studied Southern Ocean predators. OTL27c21. [39] Levels of predation may be high enough to cause a population decline at these sites.

[20], The usual food source for individuals in the Atlantic Region is Antarctic krill (Euphausia superba); while in the Indian Ocean the diet is mostly based on fish and squid. In the Atlantic region, the Antarctic fur seal usually eats Antarctic krill.

The nose does not extend much past the mouth, the external ears are long, prominent, and naked at the tip. Subsequent monitoring of entangled fur seals confirmed that entanglement is still a persistent problem, but it has halved in recent years. [12] However, there are regional differences in population trends: some colonies are increasing in size (e.g. Whiskers on the Antarctic fur seal are the key in new research that helps to understand food webs in the Southern Ocean.

Antarctic fur seals breed in colonies and are polygynous. [22] Seasonal differences in diet have been recorded across colonies, seasons and years. This expedition cruise passes through waters travelled by Humpback, Minke and Fin whales. Males will fight each other for the right to rule harems of up to 20 females (the rare harem can go up to 100 females). Current time at Palmer Station, Antarctica: Current temperature: Cold. Adult males arrive about one month before the breeding females, and establish territories. The Antarctic fur seal, unlike some other seal species, has visible ears and is the only species with visible ears living in the Antarctic.

Antarctic fur seals live up to 20 years. Genetic studies on population structure[29] have suggests that there are two genetically distinct regions: a western region including the islands of the Scotia Arc, Bouvetøya, and Marion Islands, and an eastern region, including Kerguelen and Macquarie Islands. Females can live up to 24 years. HDS32-21. [3], Breeding colonies are found at South Georgia, South Sandwich Islands, South Orkney Islands, South Shetland Islands and Bouvetøya in the Southern Atlantic Ocean; Marion Island, Crozet Islands, Kerguelen Island and Heard Island in the Southern Indian Ocean; and Macquarie Island in the Southern Pacific Ocean. Recently, a proposal was made to reassign this species to the resurrected genus Arctophoca. This issue is compounded by the complexity of fur seal behavior and how serious a bite can be[44] and the risk of transfer of diseases. [23][24] Studies have showed that female Antarctic fur seals can undertake wide-ranging foraging migrations during winter. They may also prey on some smaller penguins. Female fur seals, or cows, give birth during this breeding season, then mate again just a few days later. Antarctic Guide > Antarctic Wildlife > Seals > Fur seals > Antarctic fur seal, length: female 1.3 m/4 ft; male 1.9 m/6 ft, weight: female 35 kg/80 lb; male 135 kg/300 lb. [42] With this greater interaction comes the risk of impacting the territoriality of seals especially during the mating season. Krill makes up about 95% of an Antarctic Fur Seal’s diet. Name: Antarctic Fur Seal (Arctocephalus gazella). The deepest known dive of an Antarctic Fur Seal sits at 180 metres, the longest dive lasting about 10 minutes. [13], Antarctic fur seals have a circumpolar distribution and breed from 61° S to the Antarctic Convergence. Antarctic fur seals are thought to be the most abundant type of fur seal. The expedition explores one of the last untamed areas on Earth – a land of ruggedly beautiful landscapes and amazingly varied wildlife. In the past it has been difficult to get a clear idea of the seals' diet as they spend 80 per cent of their lives at sea.

Antarctic fur seals are member of the genus Arctocephalus.

The whiskers, known as vibrissae, act as an "archival clock", said Dr Lea. Females and young ones tend to be paler, almost grey with lighter undersides. Whiskers on the Antarctic fur seal are the key in new research that helps to understand food webs in the Southern Ocean.
