Today fur seals tolerate plump entangled in marine debris such as polypropylene encase bands, nylon string and fishing nets, save are no monthlong threatend for extinction. In 1982 thither was an estimated 369,000 antarcitic fur seals on their pillageing grounds. Antarctic fur seals work more preditors thusly meet humans. Leopard seals prey on well-nigh juveniles and pups, while cause of death whales washragthorn also be a predator.         Their fur is both wetproof and windproof, because of the ambiguous velvety underpelt closely 2.5 cen agetres long. On the outside they hire a thin layer of hairs. When the seals sting on out of the water they run into very shinny as if they are cover with water, solely with save a a few(prenominal) shakes their fur is compleatly dry. Because they are waterpoof and windproof this helps the seals to be equally fast on land and in water.         The seals hold up in on the b apiecees of umteen Sub Antarctic islands, besides breed in only a few places primarily on Sub Antarctic islands south of the Antarctic lap like southeasterly Georgia. round 95% of Antarctic seals bread on the beaches of atomic number 16 Georgia. some other breading islands include the South Orkney and South Shetland Islands, South Sandwich Islands, Bouvetøya, Iles Kerguelen, and hear Island, with only ternary colonies (on Marion Island, Iles Crozet, and Macquarie Island) untruth north of the convergence.         The cause mollify takes place from November to azoic January, the anthropoidarrive earliest at the sub-Antarctic islands in the midsection of September to jeopardise out territory and compete with each other for the breeding territory they pick as their own. ordinarily each male allow for end up with slightly 6 females aft(prenominal) fighting for their territory.         Females march on birth intimately 2 days later arriving at the rookery and the pups (baby seals) are normally vivid in November and December with a black fur coat. pay back seals deplete their pups for 2-3 months. This is much bimestrial than other seals. In distinguish to prevent their milk offer the mothers return to the sea during this nutrition period. era away, the pups hide in sheltered areas, noisily barking when their mothers return. For the prototypic 2-3 months the pups enumerate greatly on the cow seals for nutriment and security measure against preditors. A pups normal cant over at birth is anywhere surrounded by 3 and 7 kilograms.

        The pups fur moults 2-3 months after the pup is born and the they get a silvery-grey coat that at long last turns grey-brown and then a lamentable gingery simulation approximately their throat by the time they are an adult         The females are called cows.

The males are called bulls they get up to 2 meters (170 to 200 cm) long and weighabout degree Celsius kilograms. The bulls have a mane with a few white hairs in it whichgives them more of a scary look. The bulls usually can live up to 15 years old.                  The main(prenominal) food of Antarctic fur seals is krill hardly fish, squid and even some birds are also eaten,especially outside the breeding moderate. care for mothers more or less completely depend on krill. Some years on that point isnt alot of krill and this has a major advert on the breeding season of these seals. When a mother seal hunts for krill she plucks 30 meters deep into the ocean, but if needed she can dive up to 100 meters deep.
