Underwater tales from marine biologist at Constance Halaveli
Robin Aiello, renowned marine biologist, is at Constance Halaveli this month. Enjoy tales of her underwater adventures and find out more about your dive buddies with the special creature features she’s writing for us during her stay.
Arriving at Halaveli
It is hard to believe that I have been on this wonderful island for a week already. Time is passing too quickly and there is so much to do, and see, and explore.
I arrived last Sunday to the resort by seaplane – which in itself is a fabulous experience with wonderful views of the reefs and lagoons while enroute.
I’m staying in a Water Villa. It’s spectacular, and for me, living somewhere I can step out onto my deck and down a few stairs directly into the ocean for a snorkel is a dream come true.
Within the first few minutes of snorkelling from my deck I encountered a school of silver mullet fish hungrily feeding at the surface of the water, saw several baby blacktip reef sharks (only about 40cm long, so they were only a few days old), and spotted a manta ray passing by. Wow! What a start to my month on the island.
While I’m at Halaveli, I’ll be working with the TGI Dive Center guiding dives and snorkels and sharing all my expertise on coral reefs and the animals living there.
One of the things that has really impressed me is the diversity of the marine life on the reefs that we visit. There is just so much to see. During my stay, I’lll be writing a series of Creature Features in which I want to highlight some of the lesser well-known creatures that you can easily see while diving and snorkeling. I hope you enjoy the fun facts.
Creature Feature 1: The Redtooth Triggerfish (Odonus niger)
Also known as Black Triggerfish or Niger Triggerfish
As soon as you put your head into the waters on any of the reefs here, you can see why people come back for diving over and over again to the Maldives. The ocean is full of marine life – in every imaginable shape and colour. It is like being inside a large aquarium.
All around you fish dart to and fro – some are very curious and even change direction to pass close to your mask and look you right in the eye.
Many people ask me which is my favourite fish, and to be honest, I cannot choose – they are each so beautiful and interesting in their own way. But there is one fish that I have developed a great fondness for since being here in Halaveli – the Redtooth Triggerfish. To me, these are incredibly endearing.
Their behaviour
These fish are schooling fish that feed on zooplankton floating in the water, so they form massive groups of hundreds, if not thousands, of individuals. They hang off the edge of the reef, forming a ‘halo’ around it.
All triggerfish are easily recognised by the way they swim – they undulate their ventral (top) fin and dorsal (bottom) fin from side to side, so it almost looks like flags flapping in the breeze. When there are hundreds of fish doing this all at once, the motion is mesmerising – like a fish ballet.
Although on first glance they do not look like this would be an effective way to swim, these fish are actually highly maneuverable. They flit around in the water column catching small zooplankton (small animals that float in the ocean). In fact, when you take a close look at these fish, you can see that their tiny little mouths are upturned, pointing upwards, which makes it easier for them to grab zooplankton floating by.
Recognising the Redtooth Triggerfish
The Redtooth Triggerfish is known by many names, including Niger or Black Triggerfish. Although they can reach up to 30cm long, they are generally much smaller – about the size of you hand.
Their colours vary greatly depending on the light conditions. When schooling in deep, blue waters they appear black, but in good sunlight you can see their true bright blue or teal green colouration. And, yes, when you get a close up look at the teeth, they are in fact a dark red colour (no one seems to know why they are red). Around the head they have delicate lines that create a beautiful facial tattoo. However, for me, the most beautiful part of these fish are their long lyre-shaped tails that wave in the currents.
The triggerfish spine
All triggerfish have a shared characteristic – a spine (the ‘trigger’) on their forehead. This is a special spine that they can erect and lock into place with a second spine – much like a trigger on a gun, hence the name ‘triggerfish’.
They use this unique feature in two ways. One is for defense against being eaten by predatory fish. Imagine a fish’s surprise if it tries to swallow a triggerfish and suddenly it gets spiked in their throat by the ‘trigger’ spine.
But the most important use of the ‘trigger’ spine is for tightly wedging themselves into coral crevices or small holes in the reef while they sleep (yes…reef fish DO sleep). To stay safe, these fish find their own personal hole or crevice in the reef to hide out in. The spaces are usually so narrow that the fish need to wiggle into them by turning sideways.
Once inside the hole (usually all you can see are thee tips of the tail sticking out) the triggerfish erect their ‘trigger’ spine to lock themselves in place. In this way, any predatory fish, like a reef shark who hunts sleeping fish, cannot grab and tug them out from their holes.
When the triggerfish are ready to leave the holes, they release the ‘trigger’, lower the spine and wiggle their way out – backwards! (Yes…these are one of the few fish that I have seen that can swim tail-first!
So the next time you are diving on one of the reefs around Halaveli, take a moment to observe these little triggerfish.
Regarded by ‘Lonely Planet’ as one of the premier destinations for diving, Ellaidhoo Maldives by Cinnamon is a tropical haven where lush greenery meets the expansive ocean. Surrounded by vibrant coral reefs brimming with marine life, the resort offers a rare combination of tranquility and adventure, providing guests with an extraordinary connection to nature. However, with global challenges such as climate change, overfishing, and pollution threatening marine ecosystems, the Maldives faces an urgent need to protect its delicate underwater environments.
In response to this growing responsibility, Ellaidhoo Maldives by Cinnamon has taken a significant step in environmental conservation by establishing a dedicated Marine Biology Unit. This initiative aims to promote marine conservation and inspire a collective sense of responsibility among guests, staff, and the local community.
The Marine Biology Unit, formerly the resort’s library, has been transformed into an educational hub promoting sustainable tourism and ecological awareness. Led by Cinnamon Hotels & Resorts’ first and only female marine biologist, the unit brings a unique and empowering perspective to marine conservation efforts. It provides an interactive space for guests to explore the intricate world of marine life, covering topics such as coral health and the behaviour of local fish species.
Daily educational sessions offer insights into the complex ecosystems of the ocean, with topics ranging from the marvels of coral reefs to the fascinating behaviours of the region’s marine life. To spark interest, the unit displays the day’s featured topic at its entrance, encouraging guests to participate. Fish identification checklists are also made available, helping visitors enhance their knowledge as they explore Ellaidhoo’s vibrant reefs.
General Manager of Cinnamon Hotels & Resorts, Sanjeeva Perera, emphasised the significance of this initiative, stating, “The launch of our Marine Biology Unit is the realisation of a long-awaited dream and a meaningful contribution to our ESG initiatives. Our mission is to empower guests and staff to become true stewards of the ocean, fostering a deep respect for marine life that will resonate long after their stay at Ellaidhoo Maldives by Cinnamon. We hope this initiative not only enriches their experience but also builds a foundation of environmental responsibility that extends to the wider community.”
A longstanding advocate for eco-friendly practices, Ellaidhoo Maldives by Cinnamon recognises the critical importance of preserving the island’s extraordinary natural beauty. By involving guests as active participants in environmental protection, the resort aims to create a lasting positive impact, cultivating a shared commitment to safeguarding the pristine marine environment for future generations.

Velassaru Maldives has announced the launch of the Velassaru Coral Project, a new initiative designed to engage guests in marine conservation while supporting coral restoration and promoting marine biodiversity. This immersive project allows guests to actively participate in building an artificial reef, fostering a deeper connection with the environment during their stay.
As part of this initiative, guests can purchase a coral frame, which is adorned with coral fragments collected and secured by Velassaru’s marine team. Each frame includes a personalised plaque, offering participants the opportunity to leave a lasting legacy in the Maldives. Over the following two years, guests receive biannual updates on the progress of their coral, with photos and videos documenting its growth and development.
Velassaru’s dedication to education ensures that participants understand the essential role coral reefs play in sustaining marine life and supporting local communities. Though they cover only a small fraction of the ocean floor, coral reefs are home to 25% of all marine species, providing shelter and sustenance to fish, invertebrates, and other sea creatures.
Certified and novice divers alike are invited to explore the artificial reef near the Immersion Dive Centre, where professional guides lead dives and offer insights into the coral regeneration process and the thriving marine ecosystem around the reef.
A highlight of this manmade reef is “The Dome,” an impressive 4-meter by 6-meter structure situated 10 meters below the water’s surface. Sunk on September 12, 2024, The Dome offers an accessible dive site for Velassaru guests to explore and nurture. During underwater excursions, divers are encouraged to monitor the health of the corals, maintaining fragments secured with zip ties and fishing line.
In addition to enhancing guest experiences, the Velassaru Coral Project aims to gather essential data for coral research. Each dive at the artificial reef includes an assessment of coral health, with detailed records on coral colour, size, and species. Regular checks also monitor environmental factors such as water temperature and quality, as even a two-degree rise can cause coral bleaching. The team will remain vigilant in observing common coral diseases like white syndrome and pests that threaten coral health.
Sharks have occasionally been sighted near smaller reefs close to the artificial site, and the Velassaru team hopes to see more shark sightings as coral and fish populations grow. These predators play a vital role in balancing the ecosystem and ensuring the health and diversity of the surrounding reefs.
All data collected from the Velassaru Coral Project will be shared with Coral Watch, a global database that compiles information on coral health and conservation efforts. Through this contribution, Velassaru guests are not only helping restore the Maldives’ reefs but are also supporting coral research and preservation worldwide.
By involving guests in this unique, hands-on experience, Velassaru Maldives aims to encourage coral growth, enhance marine biodiversity, and provide a meaningful, educational experience for all visitors. Together, these efforts contribute to a sustainable future for the oceans.
