The Heat Is On: Sea Turtles Are Becoming Mostly Female Due To The Earth’s Warming Climate

Some of the more charismatic inhabitants of the reef here at Gili Lankanfushi are the Turtles, and we do our best to help them thrive.

In fact, our resident Hawksbill Turtle, the aptly named ‘Gili’, was initially found here in critical condition, but was rescued by our marine biology team who sent her straight to the Four Seasons Rehabilitation Centre for recovery. Of all the threats posed to these animals; poaching, entanglement in fishing gear, plastic and other marine debris, and ocean pollution – There is one issue you may not be aware of: Climate change is turning Sea Turtles female.

As reported by Sarah Kaplan for The Washington post, scientists in the 1980s accidently discovered that temperature can determine the sex of Turtles. The team were attempting to aid a population of sea Turtles by rescuing eggs from vulnerable beaches and keeping them warm in incubators until they were ready to hatch. To their surprise almost all the hatchlings were male. What these scientists observed was “Temperature-dependent sex determination (TSD)”, a phenomenon that occurs only in reptiles (and some fish).

At what biologists call the ‘pivot temperature’ (roughly 29oC for Green Turtles), nests will produce equal amounts of males and females. A little warmer and embryos develop as females, but keep the eggs just a few degrees cooler (like the scientists did with their incubators) and they’ll come out mostly male.

Turtles tend to target their breeding periods to times when the sand is slightly warmer than their pivot temperatures, resulting in populations moderately skewed towards female, but a recent study conducted around Australia’s Great Barrier Reef found that the populations are becoming more than moderately skewed. On the warmer nesting sites 99.1% of juvenile Green Turtles were female, as were 86.8% of adults, suggesting that there has been a shift in gender ratios over the last few decades.

Scientific evidence for warming of the climate system is unequivocal
-Intergovernmental Panel on Climate Change

Global warming is rapidly emerging as a universal threat to ecological integrity and function, say scientists studying coral reef assemblages. In species with temperature-dependent sex determination the impacts of rising temperature are particularly pertinent. At the key breeding grounds of many Sea Turtle populations the sand has warmed significantly since the 1990’s and researchers say that this almost certainly accounts for the dramatic decrease in the number of males. Since turtles will often return to the same beaches where they were born to lay their own eggs, this cycle will likely continue; and with global temperatures continuing to rise, many Sea Turtle populations are in danger of high egg mortality and female-only offspring production.

“Finding that there are next to no males among young Northern Green Turtles should ring alarm bells, but all is not lost for this important population.”
– WWF Australia CEO Dermot O’Gorman

The good news is that management strategies are possible. Options include shading beaches or using artificial rain to cool the beach. Protecting some of the big breeding males from threats such as poaching and entanglement is also going to be of particular importance.

Of the seven species of sea Turtles in the world, five species have been recorded in the Maldives and some species are known to nest here: The Green Turtle (Chelonia mydas), Hawksbill Turtle (Eretmochelys imbricata), Olive Ridley Turtle (Lepidochelys olivacea), Loggerhead Turtle (Caretta caretta) and Leatherback Turtle (Dermachelys coriacea). The Maldivian archipelago clearly serves as an important habitat for Sea Turtles, and here at Gili Lankanfushi we strive to help maintain that habitat by educating our guests about the negative effects of global warming; reducing the amount of harmful marine debris entering the ocean and growing our seagrass beds that act as a carbon sink and produce food for our sea turtle population.

So, what can you do to help mitigate climate change? Start by finding ways to reduce your carbon footprint; embrace a minimalist lifestyle, walk instead of drive, [a comprehensive list of ways to reduce your carbon footprint can be found here and here] and support only the large companies that are reducing theirs too.

Green Sea Turtle Nesting on Earth Day 2018

In the early hours of Earth Day, 22nd April 2018, a female green sea turtle was coming to an end of her journey as she finished laying the last of her 150 ping pong ball sized eggs in the sand close to the tree line at Gili Lankanfushi.

The adult turtle was around one meter in size with her carapace (shell) measuring around 80cm. After arriving on the beach just before high tide (at 4:30am) she searched for a safe spot to lay her eggs in an area where the sand was soft enough to dig a hole around 50 cm deep.

She succeeded on her second attempt and went into a trance to deliver her clutch. We did not want to disturb her but used this opportunity to assess her size and check the hole was deep enough for her eggs.

After a two-hour process, she began to make her way back to the ocean. Her energy levels were high and her timing impeccable as she re-entered the water at 6:15am, just before first light.

The nest is in an area that could be disturbed by hosts or guests walking, so we constructed a make shift boundary to protect the eggs from the pressure of human feet above.

After a 60 day incubation period we hope to witness the emergence of the hatchlings as they make their way down to the ocean. Turtle hatchlings follow the light of the moon to reach the ocean so we will be sure to turn off external lights during this time as any light pollution could cause the hatchlings to make a wrong turn and reduce their chance of survival.

Female green sea turtles nest three to five times per season and they lay their eggs on beaches within a 100kilometre radius of where they hatched. We hope she is planning to nest again on Gili’s shores in the next few months. We noticed a unique marking on her carapace and we will try to use this white mark to identify her in the future. However, we were not able to get clear photographic identification as we did not want to disturb her behaviour by shining a light on her.

As she entered the water, we became acutely aware of the responsibility we had been given – to keep these eggs safe from disturbance and predators for around two months until they emerge as hatchlings.

As only one in 1000 turtle hatchlings make it to adulthood we can safely say that Gili is carrying precious cargo into the months ahead.

Earth Day – Sunday 22nd April

On Sunday 22nd April, the Prodivers team and guests of Hurawalhi joined the largest civic-focused day of action in the world – Earth Day! The campaign for Earth Day 2018 was ‘End Plastic Pollution’, a movement dedicated to providing information and inspiration needed to fundamentally change human attitude and behaviour towards plastics.


Plastics are a substance the earth cannot digest. The very qualities that made plastics such an attractive material initially; durable, flexible, versatile and inexpensive, have ultimately generated rubbish with staying power – a huge environmental issue. Our voracious appetite for plastic goods, coupled with our tendency to discard, litter and thus pollute, has led to an estimated 8 million tonnes of plastic entering our oceans every year. Plastics not only threaten our wildlife through entanglement, ingestion and habitat disruption, but their ability to absorb chemicals and accumulate in the human food chain has also led to plastics negatively affecting human health.


So, instead of diving with sharks or snorkelling with manta rays, the 48th Earth Day saw Hurawalhi staff and guests dive and snorkel for debris instead! They were let loose to clean up as much plastic and rubbish they could find off a nearby reef. Whilst they may have made only the tiniest dent in removing some of the debris currently be in our oceans, every action counts. There are so many simple ways to reduce plastic consumption in our day-to-day lives, here are some of the tips our Marine Biologist, Kirsty, shared with all of our volunteers this Earth Day:

1. Refrain from using plastic straws, even in restaurants. If a straw is a must, purchase a reusable one.

2. Forget the plastic bag. Purchase a reusable produce bag and be sure to wash them often.

3. Give up gum. Chewing gum is made of a synthetic rubber, i.e. plastic.

4. Ditch bottles for boxes. Often, products like laundry detergent come in cardboard which is more easily recycled than plastic.

5. Leave the single-use plastic bottles on the shelf. Use a reusable bottle or mug for your beverages, even when ordering from a to-go shop.

6. Don’t buy foods in plastic containers e.g. berries, tomatoes etc. Ask your local grocer to take your plastic containers back.

7. Disregard the disposable nappy. Use cloth nappies to reduce your baby’s carbon footprint and save money.

8. Stop purchasing single serving products. Buy bulk items instead and pack your lunch in reusable containers and bags.

9. Refuse to buy disposable razors and toothbrushes. Purchase replaceable blades instead.

Abstain from buying frozen foods. Even though those that appear to be packaged in cardboard are coated in a thin layer of plastic, plus you’ll be eating fewer processed foods.

A great quote from Marine Biologist, Sylvia Earle, sums up perfectly the importance of looking after the ocean: ‘No water, no life. No blue, no green’

PADI’s guest blogger Kirsty introduces herself:

Growing up in Mallorca, surrounded by the riches of the Mediterranean Sea, Kirsty’s ambition to pursue a career in marine biology was ignited from a young age. Kirsty completed both her undergraduate and postgraduate degrees at Newcastle University in England. During her studies she had the opportunity to conduct fieldwork in the Bahamas, Bermuda and the Maldives. It is not surprising then that her research interests to date have focused on tropical reef ecology. More specifically, Kirsty is interested in studying the movement patterns and habitat use of sharks and rays. Kirsty is currently part of the Maldivian Manta Trust research team, collecting data around the country’s manta population, its movements, and how the environment and tourism / human interactions affect them.

 

 

Earth Hour

Earth Hour is an annual worldwide movement to encourage individuals, communities, and businesses to conserve our resources. Celebrating it is a symbol of our commitment to our planet.

At Gili we celebrated Earth Hour on March 24th with the rest of the world, we hosted a Coral Conservation themed day with multiple events leading into each other. For each event, all guests and hosts were invited to attend and take part.

Our first event was a coral workshop hosted for Marine Biologists and enthusiasts. In attendance were three participants from our local island Himmafushi who have a keen interest in protecting their reef and inspiring locals. Additionally, Marine Biologists from Four Seasons Resort, Bandos Resort, Atoll Marine Centre and Hurawalhi Resort attended. Jinah, a journalist from Hotelier Maldives covered our event celebrations.

Our coral lines project launched in 2014 and currently has 190+ lines, each containing around 50 coral fragments. The aim of the project is to rehabilitate our degraded house reef through direct transplantation of mature corals and through indirect coral spawning from the nursery. The project was the first low-tech and high efficiency coral recovery project that involves rope in the Maldives.
Due to the optimal location and care that goes into the project we had 68% survival after the El Nino event and the crown of thorn starfish outbreak. Due to the success of our project, many Marine Biologists are interested in learning more as they want to launch their own projects or further their current projects in other locations. This is why we invited them to join us in celebration of Earth Hour.

 

We felt that hosting a coral conservation themed day would create a platform for a discussion on possible project improvements and new project ideas. Overtime the coral line nursery will contain heat tolerant coral species, fragmenting these species and planting lines could lead to natural spawning of more heat tolerant species which will increase survival rate in future warming events. This will lead to the creation of more healthy reefs decreasing the pressure of predation, providing a healthier habitat, refuge and nurseries for marine organisms like turtles, juvenile fish and other fish species as well as conserving a key ecological ecosystem.
On the day the visiting Marine Biologists arrived at 14:00pm and a land based presentation was carried out, topics included an in depth overview of the project, project creation, management, challenges and future plans. This was followed by a practical demonstration of making a coral line, monitoring the lines and general maintenance including cleaning and removal of invasive species. To view the coral line made by the Marine Biologists click here. To conclude there was a group discussion on possible project improvements and a question and answer session.

 

Following the success of the coral workshop together with guests, Marine Biologists and hosts we designed and created a coral shape in the sand on Library Beach. In celebration of the official Earth Hour which is between 20:30 – 21:30 we turned off none essential lights and filled the coral shape with sustainably sourced candles – coconuts and used cooking oil. During the official event our coral shape was beautifully illuminated by flickering candle lights and guests, Marine Biologists and hosts were able to enjoy this display whilst attending our Earth Hour cocktail evening.

 

To conclude our Earth Hour celebrations we hosted the documentary Chasing Coral in our Jungle cinema and Host Village. Chasing coral is a fantastic documentary about a group of divers, photographers and scientists who set out on an ocean adventure to discover why the reefs are disappearing and to reveal the underwater mystery to the world. They found that coral reefs around the world are vanishing at an unprecedented rate and documented their discoveries and explained them in a way that is accessible to everyone.
Overall the event was a huge success with all participants learning something new and being inspired to help conserve our resources. We hope that you will join us in celebrating Earth Hour next year!

Green Sea Turtles hatchlings on Kuredu

Guests at Kuredu Resort recently had a very cute surprise in the sand: a green sea turtle nest hatched! Late in the evening, while walking back to their villa, the guests spotted the tiny turtles making their way quickly across the beach into the ocean. A few hatchlings wandered astray and were collected by resort staff, soon to be released under the supervision of resident Sea Turtle Biologist, Stephanie, along with volunteers from the Prodivers Team.

According to previous reports, it takes green turtle nests 49 to 62 days to hatch here in the Maldives, but the baby turtles on Kuredu were a little slower – it took them 64 days to make their way out of the nest.

To evaluate the hatching success of the nest, Stephanie and a volunteer digging team from Prodivers went to exhume the nest 48 hours after the hatching event. After quite some digging, they successfully discovered the nest and out of 105 eggs laid, only three had failed to develop – that’s 102 more baby green turtles in the ocean! Such a successful nest is great news for the sea turtle population and we hope to see some of the hatchlings back on Kuredu to nest in about 10 to 15 years’ time.

Snorkelling or scuba diving at Kuredu Island Resort Maldives gives a very good chance of seeing turtles – the island is blessed with a large community of green sea turtles that can be seen at Caves, either on a Prodivers snorkelling excursion or dive trip. Turtles can also be spotted grazing in the lagoon.

Want to learn more about turtles? Visit Stephanie at Kuredu’s Marine Center and join her snorkelling on the reef for a turtle tour while she collects valuable data for the Olive Ridley Project.

Common crabs encountered in the Maldives: Part 2

Crabs are an underappreciated species. Whilst living in a harsh and arid environment they dedicate their lives to keeping the beach pristine.

Swift-Footed Rock Crab

The swift-footed rock crab can easily go unnoticed due to its elusive behaviour. It inhabits rocky shores at mid to high tide level and so can be found around beach rocks, boat ramps, rock walls and jetties. These crabs are fast moving and are generally only seen at night, unless disturbed. Then you may observe them jumping from rock to rock trying to find a new refuge.

Their colouration can be mesmerising with a multitude of blue, green, purple, orange, white and black. The crabs encountered on Gili are more blue, green and purple with white stripes. The shell (carapace) can be up to eight centimeters wide and is flattened, compared to other crabs which have shells that are more rounded.

The crab feeds on algae, detritus, small vertebrates, barnacles, limpets and snails. They use their claws to break into the shells of other animals and to tear off pieces of their prey to be transferred into their mouth. This species is predated upon by a variety of animals including birds, octopus and fish, so it isn’t safe for them in the ocean or out of it!

Fiddler Crab. Picture by Carly Brooke

Fiddler crabs

Fiddler crabs are a small and short lived species of crab (up to two years) and are closely related to ghost crabs. They are found in mangroves, brackish water, mud flats, lagoons and swamps. The colouration of the crabs change in correlation with circadian rhythm – during the day they are dark and at night they are light.

Fiddler crabs are well known for their sexual dimorphism – the male’s major claw is much larger than the females. If the large claw has been lost the male will develop a new large claw on the opposite side, which will appear after molting. The female’s claws are the same size. The crabs use their claws in communication, courtship and combat. The male claw is used in waving displays which signals to the female that they are ready to mate. A more vigorous waving display indicates a healthier male and a larger claw indicates a wider burrow which will provide better temperatures for egg incubation. Females chose their partners based on claw size and the quality of waving. Once a female has been attracted she will reside in the male’s burrow whilst the eggs are being laid. The female will carry her eggs on the underside of her body for a two week gestation period. After this period the female will venture out of the burrow and release the larvae into a receding tide.

During feeding the crabs move their smaller claw from the ground to their mouth. This movement looks like the crab is playing the smaller claw like a fiddle – hence the name, fiddler crab. The smaller claw is used to pick up the sediment which is then sifted through in the crab’s mouth. Algae, microbes and fungus are the preferred diet of the crab. After the nutrients are extracted the sediment is placed back onto the ground in a ball. The feeding habits may play a vital role in preserving the ecosystem as they aerate the soil. The fiddler crab can be seen when visiting local islands, especially in the mangrove area at low tide

Common crabs encountered in the Maldives: Part 1

Crabs are an underappreciated species. Whilst living in a harsh and arid environment they dedicate their lives to keeping the beach pristine.

The Maldives is rich in life and biodiversity, but the majority of this diversity is marine based. Due to the great distance of the Maldives from large land masses there are relatively few land based species. Crabs, are one of the most common. These shy little critters are abundant, entertaining to observe and vital to the island’s survival.

Land Hermit Crabs

Land hermit crabs are completely adapted to life on land, living under leaf litter or in other sheltered areas. A common error made by people is completely submerging these crabs in water, mistaking them for marine animals. Unfortunately hermit crabs can only survive for a few minutes when completely submerged. They are not true crabs because they do not have their own shell. Instead they use shells from dead gastropods in order to protect their soft abdomens. They are a long lived species – sometimes reaching the age of 40 years and older – so they go through a lot of shells!

Hermit crabs start their lives moving through a variety of larval stages whilst floating in the ocean. The larvae spend the first 40 – 60 days of their life alongside plankton until they change into a hermit crab/lobster shape. In this final larval stage they find a small shell and over the period of a month will spend more time on land until they finally molt and leave the ocean for good. By feeding on vegetation, insects, detritus, other smaller hermit crabs and microbes in the sand the crab grows in size. To accommodate this growth their hard exoskeleton must be shed periodically during the year and this process will carry on through-out the hermit crab’s life. As they grow in size the hermit crab molts less frequently and the molt process takes longer, during which time the crab will stay completely submerged in the sand.

When sexually mature the male will knock on the female’s shell to signal mating. Both genders will then extend out of their shells and the male will fertilise the female. After fertilisation the female will carry her eggs around on her abdomen where they are protected from predation. The bigger the female the larger the quantity of eggs. After one month the eggs are fully developed and the colour of the egg will have changed from brick red to grey. To hatch the eggs the female will enter the water at low tide. Upon contact with water the eggs burst open and the larvae are released.

Ghost Crab. Picture by Hans Hillewaert

Ghost Crab

Another common crab species is the ghost crab which is aptly named due to its nocturnal activity and sandy colouration, making the crab perfectly camouflaged into the beach backdrop. These crabs are found on sandy beaches and live in burrows. The narrower and shorter the burrow the smaller the crab. Their burrows serve a number of purposes: protection from predation, storage of their food, protection from drying out and other extreme weather conditions as well as a place to mate (although not all ghost crabs mate in burrows).

Young crabs and female crabs create burrows with sand scattered everywhere, with young crabs preferring to create burrows nearer to the water, whilst male crabs have burrows with a neat mound of sand outside – the larger the crab the larger the mound. Males produce mating sounds, squeaking noises, in a variety of ways; by rubbing their right claw on their leg, by rubbing their legs together, or by using their gill chambers, which they keep moist with saltwater.

After mating the females store thousands of eggs inside an abdominal flap. She will then venture into the sea when the eggs are ready to hatch. Since ghost crabs cannot swim the female will float upside down in the water allowing the eggs in her abdomen to breathe. Upon contact with saltwater the larvae are released and after two months return to land.

Swift-Footed Rock Crab. Picture by Laura Pola

The exoskeleton of a ghost crab is water tight, which prevents the crab from drying out in the arid and salty conditions on the beach. All ghost crabs have eye stalks with the males additionally having horns. These eyestalks enable the crab to see in any direction and can be stored in groves on their shells. The ghost crab’s eye sight is so good that they are able to catch insects’ mid-flight. They also have a well-developed sense of smell. They are very agile, capable of moving at 10mph, which makes them the fastest of all crustaceans.

Due to the erratic nature of their food supply ghost crabs are very protective of their food and will use their claws in combat displays. Male ghost crabs have one claw that is slightly larger than the other and combat is normally non-contact and ritualistic. Ghost crabs spend the majority of their day looking for food and particularly like to eat fish, seaweed, microbes in the sand, jellyfish, other crabs, snails, turtle hatchings and really anything they can get their claws on.

Maldives plastic recycling on a local islands

Gili Lankanfushi conserves our limited resources and cleans up our islands to help preserve our future.

Following the success of plastic recycling on Gili Lankanfushi we took the leap and expanded our project. On November 2nd Gili Lankanfushi visited Himmafushi, a local island and a big producer of plastic waste due to their plastic water bottle factory. With the assistance of the local NGO Parley, who are spearheading plastic recycling in the Maldives our aim was to implement a plastic recycling project at the school and expand this throughout the island. Together with Parley, the teachers and local council members in attendance Gili Lankanfushi conducted a 30 minute presentation including two activities which all the children participated in. The presentation was well received and the council were positive regarding expanding recycling to all areas of the island. After the school visit 50 staff from Gili Lankanfushi conducted an island plastic clean to demonstrate how easy it is to recycle plastic and what types of plastic can be recycled. A huge amount of plastic was collected and on seeing this the Himmafushi local community has also become inspired to recycle their plastic waste. Gili Lankanfushi will remain in close contact with Himmafushi and offer support and guidance when needed.

 Throughout August 2017 on Gili Lankanfushi 280 hosts attended the sustainability training. Host mentally regarding plastic pollution, water, electricity and food waste has now changed for the better. In addition to Gili Lankanfushi’s plastic presentation Maai Rasheed from Parley visited and conducted a presentation about plastic recycling. Hosts can now be seen regularly recycling their plastic and helping with island cleans – for example the recent Himmafushi clean.

 Following the training activities aimed at increasing host water and electricity use awareness, hosts now know how to reduce wasting these resources through enhanced understanding of water and electricity requirements of common activities. They were given top energy and water saving tips, for example using the fan over the AC, turning off electrical appliances, washing full loads in the washing machine at a low temperature – 20°C, air drying clothing, turning off lights, having shorter showers, only using a small amount of water when cleaning, turning the tap off when brushing teeth, shaving and soaping up. You can make these changes too!

Raising awareness about excessive water waste
Raising awareness about excessive water waste

 Over the coming months plastic recycling, food waste, electricity and water use will be monitored. In the near future we will host a no bin day in the canteen which will teach hosts about portion and waste control. We have already observed a decrease in water use – before training the average host would use 200L of water per day – this is now reduced to 160L. We are confident that hosts will continue to reduce the waste of resources and participate in plastic recycling.

Things you should know if you are travelling to the Maldives on a budget

This blog has several parts, next week read about money and taxes……

With the advent of local island guesthouses and low cost flight carriers there has never been a more affordable time to travel to the Maldives. At Male International airport it is becoming a far more common sight to see guests arriving with backpacks and not matching Louis Vuitton luggage. These travellers are here to experience a destination previously perceived to be only for those seeking luxury. So maybe it’s time you considered putting the Maldives on your travel map!

Whilst budget travel in the Maldives is a growing sector of the tourism industry there still remains limited information available for would be travelers and backpackers. So the team at Secret Paradise put our heads together to provide what we feel are the Top 10 tips every budget traveler should be aware of.

Clearing Immigration and security

To enter the Maldives no pre-arrival visa is required, a thirty day free visa is issued on arrival to all nationalities, provided the following conditions are met:

Be holding a valid passport (requires to be valid for 6 months from date of arrival) and have a valid ticket to continue your journey out of the Maldives

Confirmation of a reservation in a tourist resort or a hotel either in the form of a hotel voucher or online reservation and have enough funds to cover the expenses for the duration of your stay (US$100 + $50 dollars per day)

The right to refuse entry lies at the discretion of the Immigration official, so make it easier for yourself and organise your accommodation prior to your arrival. Online sites such as Booking.Com, Airbnb and Trip Advisor are a great place to start or if you are looking for more of an experience and not just accommodation contact Secret Paradise.

Once you have cleared immigration, collect your luggage and enter the arrivals hall where a representative of the guesthouse or resort should be waiting for you. Importing goods such as alcohol, pork items, pornography, idols of worship and narcotics into the Maldives is strictly forbidden. To make life easier declare the Buddha that you have purchased in Sri Lanka and the bottle of vodka picked up in duty free, the authorities will hold any items declared or undeclared for you to collect as you depart at the end of your stay.

Coral Reef Research at Gili Lankanfushi Maldives

We encourage scientists to visit Gili Lankanfushi to share their knowledge with the Marine Biology team and carry out in-depth research of our local environment.

In an ever changing world, research is an important method of tracking environmental fluctuations and sharing information about our surroundings. After the coral bleaching event of 2016, Gili Lankanfushi wanted to learn more about the damage caused to our beautiful house reef. We hosted a team of experts funded by Rufford Small Grants Foundation, Chiara Pisapia, Dr Morgan Pratchett, and Deborah Burn who assessed the changes on the reef.  They focused on coral cover, coral size, and the number of young corals that have grown on the reef since the bleaching. Morgan Pratchett, the leading expert in Crown of Thorns Starfish (COTS) Ancanthaster planci, also monitored the size, sex and distribution of COTS.

 

The team carried out an initial study in the Maldives in 2016 and then returned to the same sites in 2017 in order to carefully assess any changes in their original findings.  On Gili Lankanfushi’s house reef, the team carried out line surveys at five and ten metres along the drop off and found that after the bleaching, coral cover has dropped to 6% at five metres and 2% at ten metres. This low coral cover is predominantly due to the ocean warming event in addition to COTS predation. Yet, in comparison with other study sites, Gili Lankanfushi had a higher number of coral recruits than expected which means new coral is beginning to grow again on the shallow section of our reef. This results from the hard work of Gili’s Team.

Dr Morgan Pratchett, collected data on COTS around the resort.  Despite their beautiful appearance, COTS are far less captivating once you understand the threat they pose to a struggling reef. They eat the remaining hard corals and new coral recruits. Over the past year, their population has spiked into an ‘outbreak’ therefore they have to be removed from the reef and our team works tirelessly to find each individual. Morgan brought COTS to Gili Veshi, our Marine Biology Lab, to teach us techniques on how to better understand these starfish. By dissecting individuals Morgan was able to show our team the interior of each specimen and explain if the animal was well fed or reproductive.  We were able to highlight certain features under the microscope.  We found the starfish living on our house reef were starving and not yet reproducing which leads us to believe the outbreak is over.

 

The aim of monitoring our house reef over time is to predict and track recovery of different species. We are extremely grateful to the knowledge shared by Chiara, Morgan and Deborah hope they can visit the resort again in 2018 to assess how much our reef has recovered.  We look forward to their return.

PADI’s guest blogger Clare Baranowski introduces herself:

I am a marine zoologist from the UK who has worked throughout the tropics researching mega fauna and reef ecosystems in the Caribbean and Indian Ocean. I have experience monitoring and restoring coral and surveying manta, turtle and dolphin populations. I began my career as a science communicator before moving into research and management roles, this is why I incorporate outreach and education into every project I work on and I hope to continue this at Gili Lankanfushi.
