Cape Fur Seals at Seal Island

Cape Fur Seals at Dawn  Cape Fur Seals at Seal Island Cape Fur Seals are intensely curious animals, using their large, well developed eyes and sensitive mouths to investigate virtually everything in their environment.  But when White Sharks are about, such curiosity is abandoned and all eyes search anxiously beneath the surface. Seal Islandis populated by approximately 60 000 Cape Fur Seals. Adult male Cape Fur Seals are up to 2.7 meters in length and 350 kilograms in mass. They usually mature at about 3 years, but generally do not become large and powerful enough to defend breeding [...]

Shark behaviour at Seal Island

"Polaris Attack" by a Great White Shark   (Partial Predatory Ethogram of the Great White Sharks at Seal Island) Great White Shark ‘Polaris Attack’ – the attacking shark performs a swift, vertical rush; often leaping partially or completely out of the water, with or without a seal in its mouth. If a seal is in the shark’s mouth, it typically shakes its head violently from side-to-side, possibly facilitating death or severe injury via neck trauma caused by the ‘Lateral Head Shake’. This is typically devastating, usually killing or incapacitating the seal in the initial strike. Those seals [...]

Anti-Predatory Strategies of Cape Fur Seals at Seal Island

Great Whites often sport numerous scratches on their heads, most likely caused by seals defending themselves during predatory events. From direct observation and data collected, Cape Fur Seals apparently reduce their vulnerability to Great White Sharks by: taking advantage of the expanded vigilance of entire groups. Sub-surface vigilance while rafting is accomplished via assuming a head-down posture, with only the tail and the tip of the rear flippers showing above the surface. leaving Seal Island as co-ordinated groups of 8 to 12 animals. Multiple groups – ranging from 2 to as many as 5 - leave the island [...]

Predatory strategies of Great White Sharks at Seal Island

Great Whites will often target lone Cape Fur Seals during predatory events. From direct observation and data collected, hunting White Sharks apparently: stalk surface-swimming Cape Fur Seals from near the bottom, probably relying on camouflage afforded by the murky water and the dark, rocky bottom against which their dark dorsal surfaces render the predators all but or wholly invisible. Direct observation indicated that Great White Sharks at Seal Island were very difficult or impossible to detect visually below a depth of about 2.5 metres, and that all recorded attacks took place in water at least 6 metres deep.

Great White Sharks On Fire At Seal Island

  It's here! Winter has arrived and she's greeting us with strong winds, lots of rain and great viz to come. On recent shark cage diving trips to Seal Island in False Bay‎ we have noticed a large increase of Great White Sharks ranging from mostly new sharks and a few of the old faces too. One shark in particular we have seen a few times on natural predations, scavenges and he has even breached on our decoy seal once or twice. We like to call him chopper due to a large portion of his dorsal fin being chopped off. [...]

The ‘Flying’ AIRJAWS Great White’s of Seal Island

The Unique ‘Flying’ AIRJAWS Great White Sharks of Seal Island   We have had incredible activity the past few weeks at Seal Island in False Bay. The great white sharks have been giving our tourists quite the show. We may make you wake up and get out of bed very early in the morning (and on vacation too!) but I hope it’s worth it to see our famous ‘flying’ sharks hunting seals with a vengeance. Seal Island is the only place in the world where great white sharks consistently jump out of the water as part of their hunting strategy; [...]

Great White Shark natural predations at Seal Island, False Bay

Natural predation of a Great White Shark on a Cape Fur Seal Predation is one of the most fundamental interactions in nature and one of the most fascinating interactions to observe, but predation is rarely observed in the wild. Seal Island, in False Bay, South Africa, provides unique opportunities to observe natural predation by Great White Sharks on Cape Fur Seals and to observe social interactions among both species. Breaching is one of the hunting techniques that great white sharks use to surprise and kill its prey. They  surface with such force and explosive energy that it propels [...]

My favourite thing about Seal Island is…

Shark cage diving? Choose African Shark Eco-Charters. Here is why! My favourite thing about Seal Island is... Of all the things that make Seal Island in False Bay special, one particular aspect stands out for me.  For a few short moments during sunrise each morning the island is alive with the natural predation activity of the great white sharks on the cape fur seals. While some of our guests may not be too thrilled with the very early start in the morning, it becomes well worth it for the opportunity to witness these top predators hunt. Seal Island is so [...]

Back at Seal Island

Dawn breaks over Seal Island False Bay The first day back at sea after a number of days of foul weather always makes me at bit nervous. Will the sharks still be there? Yesterday we were back at Seal Island after a stretch of wild Cape Town weather and I was excited and anxious to see what the shark activity would be like. The morning AIRJAWS trip started with a gorgeous red sunrise and clear skies; a welcomed sight after a week of rain. Predation activity was slow so we anchored up to prepare for the cage diving. [...]
