Long-nosed fur seals (Arctocephalus forsteri) are often in residence along our coast, sometimes lazing in the sun, and others frollicking in the water. Sometimes the bane of fishermen, it’s delightful to see them back from the brink of extinction. Before South Australia was even colonised, seal hunters and whalers exploited the once-abundant species almost to extinction for their pelts and oil by the 1830s. Fortunately, since their protection, they’re recovering in number, and the South Australian population makes up about 83 percent of the total number of long-nosed fur seals in Australia.
They’re fascinating creatures, often called puppies of the sea. Males can grow up to two metres long and weigh well over 150 kg, while females are much smaller and more graceful in the water. These seals are superb divers and hunters. Most dives last around one to two minutes, though some individuals have been recorded staying submerged for over ten minutes and reaching depths of more than 350 metres in search of fish and squid. They’re fast, agile swimmers and can even surf, breaking waves for sheer enjoyment. On land they’re surprisingly nimble too, using their flippers to haul themselves up steep rock shelves and ledges that seem impossible to climb. Although often reported as being in distress, seals will often float or sunbake with a flipper sticking up in the air, but they’re just regulating their body temperature. They make a whole range of odd sounds from bleats to grumbles and barks. As much as we love them, and they look so docile bathing in the sun, they are wild animals and can be unpredictable.
⚠️❎ Do not get closer than 30 metres to a seal if it is on land. In the water, prescribed vessels like jet skis and ski boats must stay 300 metres away from seals, while motorised vessels, sail boats and kayaks should not get any closer than 50 metres. Swimmers should stay at least 30 metres away. ⚠️❎
