Summing up the surprises of the 2016 white shark season, Seal Island, False Bay
White sharks typically visit False Bay’s Seal Island to take advantage of vulnerable young 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 of having an early start to the season. This was the first of many unexpected surprises the season had to offer. For February and March, we had amazing shark activity around our boat, seeing an average of 4 sharks a day and still enjoying the late summer, early autumn warm sunny days on the water.
My first time in the cage early this season
But before we got too comfortable, leaving the sharks to do all our work for us, by the end of April and throughout May, they had simply vanished from Seal Island. There were some really bizarre theories as to where they were and why from crew, clients, fishermen and local shark nuts, but even today the mystery of their temporary disappearance remains. The crew had placed all their bets on the exact date that the sharks would return, and just before we had begun to completely lose our minds (and jobs) the sharks started making an appearance again within the first week of June.
An island barren of sharks, but full of seals (with an identity crisis), however, always beautiful
I nearly jumped right off the boat seeing the first shark breach (I always go mad seeing a shark breach, every breach is different and it simply never gets old), but this was a combination of that excitement coupled with relief at the sign that “the shark drought” had potentially come to an end. July was an incredible month with both breaching activity as well as shark activity around the boat. Despite the fact that during this time the sharks were always around, every day, every trip, every hour, in fact, was different. Obviously the breaching and overly enthusiastic sharks around our boat are always a treat, but there were a few really memorable, standout moments this season. Firstly, a shark over 4 m in length, coming fully out of the water attacking a kelp gull just 3 m away from our boat, having the crew and clients very much in the splash zone (this just minutes after I had told a client how breaching was rare in the afternoon, and that I had never seen a shark go for a bird). On another afternoon in July, we had crystal clear waters with over 10 different sharks around our boat, flying at our bait and decoy consistently from all different angles! It was the best kind of chaos!

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 puppy dog, really cute but with rather sharp teeth, eating all your personal belongings. When naming and identifying individual white sharks, its usually from a distinguishing feature, scar or behaviour. However, it is incredible to see how much their behaviours’ vary, not only between the different individuals, but even for a particular shark on a particular day. With the number of times I’ve seen a shark put all its effort into the most magnificent breach, only for its targeted seal prey to get away, its not difficult to believe that a shark can have a bad day. Sometimes we’d see sharks hunting and making successful kills still visiting our boat and scavenging at our bait. Surprisingly, and unlike me, sharks don’t seem to have bottomless pits for stomachs, and therefore once they have eaten, they are often uninterested in us, or our bait. Maybe it’s a class thing – why would you eat a stale sandwich when there is fillet steak on offer? It may be more expensive, but totally worth it right?
“Zebra”- Stealing our hearts (& bait) since 2016
“Captain MF Hook”- I only have a picture of her dorsal fin because she was simply too big to fit in the frame at a massive 5 m in length (we’re going to need a bigger boat).
Another highlight this season was the revisit of the shark “Prop,” named for the propeller scars running along the leading edge and across her dorsal fin. I had first seen her in 2014 when the scars were still fresh and an unmistakable identifying feature. If it weren’t for her stumpy pectoral fin and the fact that she is a particularly large girl, closing in on 5 m, we would not have even recognised her this year. The scars on her dorsal fin had healed up so well being no more than very faint lines across her dorsal fin.
“Prop” 2014

A simple yet perfect example of the perfect predator, proving just how resilient they are and that their ability to heal and recover, is beyond comprehension. There is never a dull moment working with these animals; the more we try to understand them, the more we are left with a whole new set of questions rather than answers. Every day, heading out to Seal Island, you don’t know what you’re going to get. By describing this season as “surprising” “unusual” “unexpected” “unpredictable” is quite appropriate really, because all these words fundamentally define and describe “nature.” If nature were predictable, it would not be as fascinating as it is. To us, what appeared to be “inconsistencies” in the season, served as an important reminder of just how dynamic nature is and it has allowed us to continue marvelling in the mystery that is the white shark.

The Ocean Cleanup, the global non-profit project, has removed a verified all-time total of ten million kilograms (22 million lbs.) of trash from oceans and rivers around the world – approximately the same weight as the Eiffel Tower.
To complete its mission of ridding the oceans of plastic, The Ocean Cleanup uses a dual strategy: cleaning up the Great Pacific Garbage Patch (GPGP) to remove the plastic already afloat in the oceans, while stopping the flow of plastic from the world’s most polluting rivers.
Through cleaning operations in the GPGP and in rivers in eight countries, the cumulative total of trash removed has now surpassed ten million kilograms. This milestone demonstrates the acceleration of The Ocean Cleanup’s impact, while underlining the astonishing scale of the plastic pollution problem and the need for continued support and action.
While encouraging for the mission, this milestone is only a staging point: millions more tons of plastic still pollute our oceans and The Ocean Cleanup intends to continue learning, improving and innovating to solve this global catastrophe.
This announcement comes as governments from around the world meet to continue negotiations to develop a new legally binding instrument to end plastic pollution at INC4 in Ottawa, Canada. Representatives of The Ocean Cleanup will be in attendance and the organization will be urging decision-makers to collaborate towards a comprehensive and ambitious global treaty which addresses plastic at all stages of its life cycle and in all marine environments worldwide, including in areas beyond national jurisdiction.
It is encouraging to see that the need for remediation is reflected in the various options for potential treaty provisions. It is essential that the final treaty contains clear targets for the remediation of legacy plastic pollution, and reduction of riverine plastic emissions.
Tackling plastic pollution requires innovative and impactful solutions. The treaty should therefore incentivize the innovation ecosystem by fostering innovations that make maximal use of data, technology and scientific knowledge – such as those designed and deployed by The Ocean Cleanup.
‘After many tough years of trial and error, it’s amazing to see our work is starting to pay off – and I am proud of the team who has brought us to this point.’ said Boyan Slat, Founder and CEO of The Ocean Cleanup. ‘While we still have a long way to go, our recent successes fill us with renewed confidence that the oceans can be cleaned.’
The Ocean Cleanup was founded in 2013 and captured its first plastic in 2019, with the first confirmed catch in the GPGP coming soon after the deployment of Interceptor 001 in Jakarta, Indonesia. After surpassing one million kilograms of trash removed in early 2022, the non-profit project has since progressed to the third iteration of its GPGP cleaning solution, known as System 03, and a network of Interceptors currently covering rivers in eight countries, with more deployments set for 2024.
About The Ocean Cleanup
The Ocean Cleanup is an international non-profit organization that develops and scales technologies to rid the world’s oceans of plastic. They aim to achieve this goal through a dual strategy: stemming the inflow via rivers and cleaning up the legacy plastic that has already accumulated in the ocean. For the latter, The Ocean Cleanup develops large-scale systems to efficiently concentrate the plastic for periodic removal. This plastic is tracked and traced through DNV’s chain of custody model to certify claims of origin when recycling it into new products. To curb the tide via rivers, The Ocean Cleanup has developed Interceptor™ solutions to halt and extract riverine plastic before it reaches the ocean. Founded in 2013 by Boyan Slat, The Ocean Cleanup now employs a broadly multi-disciplined team of approximately 140. The foundation is headquartered in Rotterdam, the Netherlands.
