Part 2. Summing up the surprises of the 2016 white shark season, Seal Island, False Bay   Successfully snatched our decoy and gaping at it in the flawless water conditions   Further, seeing some of our favourite sharks returning to the boat over consecutive days, a special mention (and thanks) to some of the stars this year: “Zebra,” “Dodgey L,” “Prop,” “Jika,” “Patches,” “Captain MF Hook” “Stumpy Freddy,” “The one with the bent dorsal (Orca/Nemo)” and a few OCEARCH tagged sharks, including “Vindication” and “Maureen.” Of course once we’ve named them, we get very emotionally attached. They become like a [...]

Summing up the surprises of the 2016 white shark season, Seal Island, False Bay

Summing up the surprises of the 2016 white shark season, Seal Island, False Bay Leigh de Necker   White sharks typically visit False Bay’s Seal Island to take advantage of vulnerable young of the year Cape fur seal pups when they start entering the water to feed. This is generally between March and September, however, this season showed a number of deviations from the expected norms. We took a trip to the Island towards the end of January and before we even had any bait in the water, we had seen a shark. We were beyond excited by the chance [...]

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 [...]

Seal Island, False Bay, South Africa

Geography of Seal Island, False Bay Seal Island, False Bay is a small, elongate rocky islet with its long axis oriented roughly north-south, measuring approximately 400 by 50 metres, and with a maximum elevation of about 7 metres above the high tide line. The island has a narrow western shelf, with the water depth dropping off to a depth of 20 metres within 5 metres of shore, and a broad eastern shelf, where the water does not drop off to comparable depths until about 20 metres from shore. Off the southern tip of the island is a small, craggy outcrop, [...]

A Description of the Great White 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. [...]

What happened at lunch time May 19th at Seal Island?

What happened at lunch time May 19th at Seal Island...?! The last week has been hugely varied in terms of shark action on the African Shark Eco charters’ trips. Today was a prime example. Our morning trip started relatively slowly, we towed our seal decoy, had a shark make a slight lunge for the decoy but then head off. So we moored up, saw one great white shark swim past and then it went very quiet for a while. The call was made to change sites, and obviously as we pulled anchor only a few metres from our boat a [...]

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; [...]
