Shark Personalities of the Month
It has been a wonderful two weeks at Seal Island with such settled weather recently. We have been fortunate to have a number of days at the island with stunningly clear blue water – which has given us visibility of up to 15m at times! I have really enjoyed being able to see the reef below us and watch the behaviours of the white sharks as they have interacted with one another around the boat.
Interestingly this month we have been seeing not just two sharks at a time by the boat but up to FOUR individuals swimming together. It is very rare to see such interactions here, as usually these sharks go to great lengths to avoid each other around the bait. During one trip last week I was thrilled to witness a number of occasions with three sharks swimming around the boat, almost snout to tail and calmly swimming along as a procession of beautiful sharks. On the occasion that we saw four sharks together we really couldn’t believe our luck and both the guests and crew alike knew it was something very special to see. Two of the sharks were so close to each other that their pectoral fins were overlapping at times as they swam along together. It was magical to witness and a moment I will never forget.
The clear water has also given me the opportunity to experience the unique behaviours and personalities of the different sharks we have come to know well so far this season. Each shark has such a distinct personality and exhibits very specific behaviours around the boat. This month we have continued to see Zamalek and he is still being adorable and melting everyone’s hearts with his continual right turns close to the cage. He is such a relaxed shark and still spends the majority of his time calmly circling the cage closely and occasionally veering off course to examine the baits. He is such a joy for our divers to see and is one of those sharks that remain with us for a long time when he visits. Having said how calm he is we have however also discovered his livelier side and his interest in our decoy seal. As kitnip is to a cat, the decoy seal is to Zamalek! He absolutely adores our fake seal and we have to be very careful putting the decoy in the water when he is with us. It really switches him on to pursuit mode and he chases it constantly until he manages to get hold of it. Even then he tries repeatedly to grasp it. I have not seen a shark that keen on our decoy for a long time indeed and it certainly demonstrates a different side to Zamalek’s personality.
Another shark that is also very unique in his behaviour this month is Pinkie, the 3.1m male shark. This shark is so named because of a pink rosette on his dorsal fin and he is one of our more dominant sharks. White shark dominance is based on hierarchy and it is normal for us to see that the smaller sharks give way immediately to the larger sharks around the boat. Pinkie however appears to be unaware of his small size and is very dominant around both the smaller and larger sharks. On a number of occasions I have seen him wait until the very last moment to give way to our larger female sharks in the 3.7-3.9m size range. On more than one occasion I have expected him to receive a warning bite from these females as he refuses to give way and is positioned right in front of their mouths. They are extremely tolerant however, and let Pinkie get away with behaving so brazenly. He is going to be quite formidable when he is larger if he remains so dominant and confident. In contrast to Pinkie’s lack of submissive behaviour we have seen a gorgeous 2.0m white shark at the island last week that had quite the surprise and was understandably very submissive. This shark was approaching the top bait one day, which consisted of a tuna head that was quite frankly larger than the shark’s entire head and he followed it closely with his snout. I assume he couldn’t see around the bait as on the other side was our large 3.7m female Magnoona, who is very dominant and was also approaching the bait. The little shark had the shock of his life as he rounded the bait and was faced with swimming unknowingly into Magnoona’s face. Magnoona was calm and tolerant as always and the small shark practically leapt out of the water and swam incredibly fast to remove himself from the situation. I was delighted to see he made a cautious return later.
Magnoona has also captured me with her behaviour this month as she can be very relaxed or very lively. She veers from one extreme to the other within and between trips and when she is lively she keeps us on our toes. She is quick to approach the bait and often from depth to gain more speed. She is also very agile and executes tight turns close to the boat as she pursues her bait of choice. She mostly focuses on the top bait and is a shark that both our divers and boat-based guests enjoy because of the time she spends up at the surface with us. When she is feeling calm she is quite the opposite and cruises extremely slowly around the boat at the surface. She literally brought a tear to my eye the other day with the behaviour I describe below and because of that moment I am just a little bit in love with this lady. When Magnoona was approaching the bottom bait recently she took hold of it gently and as she then moved forwards the top bait rope drifted into her mouth. From previous observations of sharks when they take hold of the bait I would have expected a fairly strong reaction to finding a rope in her mouth. However… in Magnoona’s surprise she spat the bottom bait out and remained calm. She ever so slowly and gently twisted her head from side to side to remove the top bait rope from her mouth. Unfortunately all she managed to do was flip the top bait over her head and so had the rope around her snout. Magnoona was utterly unfazed by this and just calmly hung there as she assessed her situation and slowly tilted her head to the side as Poenas removed the rope and she went on her way. We were mesmerized by her behaviour and just how gentle she was in her approach. These animals really are incredible and continue to surprise me daily with their intelligence and gentle nature.
It has been an experience of a lifetime observing another side to the sharks’ behaviour recently; their incredible predatory activity. The best is yet to come!

Saba’s Plan for a Coral Comeback
Saba has an exciting new initiative to restore its coral reefs. This new project, running from 2024 to 2026, will focus on reviving key species in the island’s underwater ecosystems. With a collaborative team from the Saba Conservation Foundation (SCF) and Van Hall Larenstein (VHL) University of Applied Sciences, the project aims to restore both corals as well as sea urchins.
This initiative is centered around coral restoration, specifically reviving two essential coral species—staghorn coral (Acropora cervicornis) and elkhorn coral (Acropora palmata). By mapping parent colonies and using a technique known as coral gardening, SCF will create and maintain coral nurseries. These corals will eventually be outplanted at key reef sites around Saba to not only expand the number of coral colonies, but also provide essential fish habitat. The project focusses on installing coral nurseries, training staff with the newest techniques and starting with the restoration of key reef sites.
Reef Cleaners to the Rescue
It’s not just corals getting a makeover—this project also shines a spotlight on the essential role of grazers, particularly sea urchins. VHL is leading the charge on cultivating and restocking two key sea urchin species, West Indian sea egg (Tripneustes) and long-spined sea urchin (Diadema), known for their ability to keep algae in check. By removing algae, which are important competitors of corals, they help the coral to thrive. By restoring these “reef cleaners,” Saba’s project will give corals the breathing room they need to grow, setting the stage for a healthier, more balanced marine ecosystem.
From Tiny Urchins to Big Goals
The project will be funded as part of the Dutch Government’s Nature and Environment Policy Plan (NEPP) 2020-2030 for the Caribbean Netherlands, a comprehensive initiative aimed at conserving and restoring the unique natural environments of the Dutch Caribbean islands, including Saba, St. Eustatius, and Bonaire. This project is aiming for big milestones: build and maintaining coral nurseries, the expansion of urchin cultivation facilities, and the creation of a dedicated research center. By 2026, the project hopes to ramp up coral and grazer restoration, with the ultimate goal of extending these efforts across the Dutch Caribbean. By linking local initiatives to broader regional goals, Saba’s restoration project promises to leave a lasting impact on both the environment and the community.

Reef-World marks two decades of marine conservation: strengthening impact amid coral reef threats
Empowering ocean stakeholders to tackle future challenges and ensure the survival of coral reefs and humanity
2024 marks the 20th Anniversary of The Reef-World Foundation’s tireless efforts for global coral reef conservation. The UK charity is the international coordinator of the UN Environment Programme’s Green Fins initiative, known as the leading voice in sustainable marine tourism. Today, Reef-World released its 2023-2024 Impact Report outlining a year of substantive growth and impact in its marine conservation programmes.
Impact Report Highlights:
- Impressive improvements in environmental behaviours to protect coral reefs by the marine tourism industry as the global participation of Green Fins increases.
- Continued capacity building for government and NGO staff to effectively manage marine tourism activities in Asia, Caribbean and Red Sea regions.
- For the first time in Green Fins’ 20-year history, tourism operators have achieved ‘Best Environmental Performer’ status by demonstrating the lowest possible environmental impact in their environmental assessments. In 2024, three dive operators achieved this challenging milestone.
- Significant increases in global participation of Reef-World’s innovative digital conservation tools.
- 138 Green Fins dive operator members achieved the strict threshold for PADI Eco Center recognition.
- Developed four new educational materials and translated two into 16 languages to support the marine tourism industry in achieving sustainability targets.
- Establishing a new Reef-World Development strategy and recruiting new roles – Development and Programmes Managers.
- Reef-World’s board welcomes new Chair and Trustees strengthening organisational leadership.
Reef-World started as a one-person mission to inspire and empower communities to act in conserving and sustainably developing coral reefs and related ecosystems. Today, the team of 12 continues to meet this mission by inspiring and empowering the global marine tourism community to be exemplary sustainability leaders by using the Green Fins guidelines and tools to simultaneously use and protect the world’s precious reefs.
In April 2024, the fourth global coral reef bleaching event was confirmed. Reef-World’s work has never been more urgent as the marine environment, and the benefits they provide humanity, continue to be eroded by global threats. The reduction of local threats, like those from the marine tourism industry, is an essential step to ensuring a future where coral reefs survive and continue to support the millions of people who depend on their ecosystem benefits. Reef-World’s work buys time for coral reefs and related ecosystems to be resilient to the impacts of global threats.
“Right now our corals are facing the greatest fight of their existence as the terrifying predictions of the steps towards their complete extinction are starting to come true. But all is not lost, reefs are resilient and they have existed on this planet for millions of years. We must take action now, to buy time for reefs by reducing threats facing them and allowing them to react and adjust to the changing environment they need to survive in.” – Chloe Harvey, Executive Director
Looking Forwards:
Like coral reefs, the Reef-World team needs to be resilient in the face of the complex challenges of the conservation sector. Reef-World has invested significantly in developing a Culture of Care to ensure the well-being of its team on a daily basis, continuing to be an exemplary employer to enable its team to best achieve the mission for coral reef conservation.
With the foundations of a Culture of Care and organisational development laid, Reef-World is emerging from the end of a natural organisation life cycle, that brings the challenges of growth and scale, stronger than ever. With a new strategy in place to generate much needed resources, Reef-World is excited for the opportunities to leap forward, continue to scale our impact and lean into new innovations and untapped opportunities for marine conservation.
We continually strive to become a forward-thinking organisation that delivers on our goals and commitments to our stakeholders with fresh approaches and not being afraid of steering away from a “normal approach.” This approach is not only applied to our programmes of work but also internally and carries over to our Culture of Care for our team.” — JJ Harvey, Operations Director
The Reef-World Foundation is immensely grateful for the continued support of its grant funders: UN Environment Programme, IUCN’s Blue Natural Capital Financing Facility, Adventure Travel Conservation Fund, PADI Aware Foundation, and World Nomads Footprints Program.
Reef-World would also like to express its gratitude to international partners whose vital support has resulted in significant tangible benefits for our work and mission: PADI; Professional SCUBA Schools International (PSS); Explorer Ventures; 1% for the Planet; ZuBlu; Snorkel Venture, GSTC; Dive O’Clock; Seven Dragons; DiveAssure and Eco Beach, without whom these achievements would not be possible.
