Antarctic Fur Seal
Gathering in huge colonies in South Georgia, the sight is incredible!
What you need to know about the Antarctic Fur Seal
Our Expert Says… "Fur seals gather in huge numbers in November as this is the peak time for breeding. There are so many that some of the beaches are closed. Travelers in January or February will enjoy seeing the many pups who by this point are very curious about visitors!"
Unlike it might seem from its name, the Antarctic Fur Seal is actually most commonly found around the subantarctic islands like South Georgia, the Falklands, and the South Shetland Islands, rather than the icy continent itself.
Remarkably, South Georgia is home to over 95% of the world’s Antarctic seal population - some 6 million individuals live around this 100-mile long island. Seeing an Antarctic Fur Seal here is one of the few times in Arctic exploration you can be assured of an animal sighting!
Antarctic Fur Seals have a longer neck and more pointed muzzle than other members of the seal family, and they can sometimes be misidentified by visitors as sea lions. This confusion isn’t helped by the very long and obvious whiskers that adult Antarctic Fur Seals grow.
These seals are very dimorphic, meaning there’s a great difference in shape and size between males and females. While females can be up to 1.4m (4ft 6”) long and weigh up to 34kg (75 pounds), the males grow up to 6ft 6” long and can weigh an enormous 300 pounds!
One unusual condition to look out for is the “pale blonde” variant. About 1 in 1000 pups are born with this paler color, and they keep it into adulthood.
Females start arriving at the colonies to give birth in December, and they synchronize their births so well that 90% of Antarctic Fur Seal pups are born within the same 10-day window at each colony every year. The pups are weaned at about four months of age and will make their way to the sea where they can stay for several years before returning to the colony when they are mature enough to breed.
Antarctic Fur Seals in the South Atlantic feed mainly on krill rather than fish, and males will sometimes prey on penguins.
Since the end of commercial sealing, the Antarctic Fur Seal has made a real comeback and breeds in vast numbers. Their main threats are from Leopard seals who target young pups and the effects of climate change on the krill on which they rely.
Interesting facts about Antarctic Fur Seal
They are very aggressive during the breeding season, especially frustrated males without a harem. Once they reach and spread along the Antarctic Peninsula, many just want to rest and to be left undisturbed as they go through a moult, although they still get agitated with each other.
It is important to give them space at this time. Some may grunt or snarl at you, then go back to resting, and it is often the younger males (with more energy?), that may do mock charges.
At this time it is important to listen to staff. Wherever you are, remember to keep 25 to 50m from fur seals. If they do charge, hold you ground and raise you hands, and they should back off. If you turn and run they may continue to chase you.
If you get a more aggressive fur seal that continues to challenge you, try to stand you ground and make a noise to deter the fur seal by clapping you hands. But do try and avoid making a noise and too much fuss with those initial mock charges, fur seals are likely to back off and relax, rather become more agitated with everyone shouting and clapping.
Every encounter is different and with a lot of fur seals around there are likely to be staff to guide you on where to go, and areas to stay away from.
Also look out for hidden fur seals relaxing behind rocks or in hollows, and, when you walk past resting fur seals, keep an eye behind you. Sometimes, rather like a farm dog, some fur seals (often the younger ones!) may 'sneak' up behind you.
Finally, never lie on the ground with fur seals around (e.g. the low photographer pose), and be wary of kneeling.
