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 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

I have also monitored population dynamics of bird, turtle, shark and cetacean species to aid in their conservation. I started my career working in the Maldives and I have done a round trip via Greece, England and Seychelles, I hope to increase my skills set and knowledge further whilst I am at Gili Lankanfushi, Maldives.

Whale sharks of the Maldives

‘What is it? A shark? A whale? Whatever it is it’s massive!’

The whale shark is the biggest fish in the ocean, and therefore is also the biggest shark. It is one of three species of filter feeding shark; also including the basking shark and the mega mouth shark. On the 7th January we were lucky enough to spot Pedro who is a juvenile male at six metres. It was a truly breath taking moment! The best time to look for a whale shark is three to five hours before high tide and a few days before the full moon. However, finding a whale shark cannot be a guaranteed experience.

For many, seeing a whale shark is a once in a lifetime experience, with a place at the top of numerous bucket lists. These enigmatic and gentle creatures can be seen year round in South Ari Atoll, only a short seaplane ride from Gili Lankanfushi. The whale sharks are attracted to South Ari Atoll due to the vicinity of the Chagos-Laccadive Plateau, which provides very deep and highly nutrient rich water. Whale sharks are a pelagic species, able to travel around 100 miles per day and dive to at least 1600m – probably deeper, but this cannot be officially recorded due to tracking tags breaking under the phenomenal pressure at great depth.

Whale sharks are fascinating animals that predate the dinosaurs by 220 million years. All sharks, including the whale shark are cartilaginous fish, which means that their skeletons are made from cartilage, not bone. As with all sharks the whale shark’s skin is covered by dermal denticles, a substance more like teeth than fish scales. The dermal denticles are a couple of millimetres thick and protect the shark’s skin from damage and parasites. They also provide better hydrodynamics. Under this layer of protective armour is a fatty layer, around 10 to 15 cm thick that is most likely used as an energy store and protection from injuries, together with insulation during deeper dives. Whale sharks have over 300 rows of tiny replaceable teeth which are made from a stronger version of dermal denticles. Scientists are still debating the use of these teeth as whale sharks are filter feeders so their teeth are not required for feeding. Another anatomical feature which perplexes scientists is that the whale shark has spiracles. These are a breathing aid for stationary sharks, but the whale shark is classified as a highly mobile shark so what is the use? It could be that the whale shark is very closely related to bottom dwelling sharks, and it is a feature that will eventually disappear through evolution, or it could be used on the rare occasions that the shark is stationary and not feeding.

Whale sharks are known to make seasonal feeding aggregations in 20 countries, including Australia, Gulf of Mexico, Belize, Gulf of California, Seychelles and Maldives. Whale sharks feed on microscopic plankton and small fish that they suck into their one and half metre wide mouths. Their throats are much smaller in comparison; around the size of a drain pipe. They have two known methods for feeding, ram filtration and suction feeding. Suction feeding allows whale sharks to feed on more mobile prey such as small fishes, which they actively suck into their mouths, together with volumes of water that are then expelled through their gills. By comparison ram feeding is passive; the shark swims through the water with their mouth open and plankton filters in. It has been suggested that whale sharks are more suited to suction filter feeding because the gaps between their five to seven gills are small. This small gap is more effective at filtering out plankton when the shark is suction feeding. Whale sharks have very weak eyesight, they can probably only see three meters away, and so rely on their nostrils to find prey. Their nostrils are very sensitive due to their well-developed olfactory capsules; they can detect chemicals in the water produced by their planktonic prey.

Plankton tend to shelter at depths between 100 – 200m. This is the oxygen minimum zone and is not a suitable habitat for many organisms which would prey on them. Whale sharks however are able to feed at these depths and will spend the majority of their time between 50 – 250m. They do venture to deeper depths where the temperature drops to 3 degrees Celsius but scientists believe that due to the infrequency of these dives this is related to parasite removal, not feeding. Whale sharks cannot internally control their body temperature and so return to the surface to warm up and reload oxygen. This is why they can be found in the shallow waters around South Ari Atoll. During this warming and reloading period the sharks can be impaired cognitively and physically which explains their sluggish and relaxed behaviour.

Due to the sluggish behaviour of whale sharks and the shallow depths they travel in they are under threats from boats. It is estimated that 67% of whale sharks have injuries ranging from scratches to amputations. The effects of pollution, poor waste management and increased sedimentation on the whale shark population have not yet been suitably evaluated. Another issue is disturbances to their habitat resulting from tourism – if the guidelines for whale shark encounters are not followed the sharks can negatively be affected. For example, if a large group of tourists are crowding a shark it can cause the shark to dive before it has properly warmed up and reloaded oxygen. Adult whale sharks can also be targeted by great white sharks and orcas, whilst babies have been found in the stomachs of blue sharks and swordfish. In some parts of the world whale sharks are hunted for their meat and fins. In 2010 the Maldives implemented a ban on all forms of shark fishing. However, due to the longevity of whale sharks it will take many years for the population to return to optimal levels.

It is estimated that whale sharks can live between 70 – 100 years, reaching sexual maturity after 25 years at a size of eight to nine metres. Although some people report sightings of whale sharks up to 18 metres in length the largest confirmed has been 12.65m. It is easy to identify a male whale shark because when it has reached sexual maturity their sexual organs have a ragged appearance called claspers which extend past their pelvic fin. The whale shark is classified as ovoviviparous which means that they produce eggs which hatch inside the body. A female whale shark can store sperm for many months and can have babies at different stages of development. For example a female was found with 300 embryos at numerous stages of development. Due to whale sharks storing sperm and having babies at different stages of development the gestation period is unknown. Upon birth the pups are around half a metre in size and weight one kilo.

Whilst whale sharks are regularly sighted, 98% of these sightings are juvenile males with a length of six metres. At any one point it is estimated that there are 200 whale sharks in the waters of the Maldives. The most common behaviour observed of these sharks is cruising, only 12% of encounters are feeding.

We can’t wait to show you these gentle giants next time you are at Gili Lankanfushi. Please ask your Mr/Ms Friday and we can book a trip for you.  When you see one be sure to snap a photo of the checkerboard pattern on their side by their pectoral fins. This can help us with identification and research.

Bioluminescence at Gili Lankanfushi

The sea never sleeps. Even at night it is bursting with a wonder that seems almost magical – flashes seeming to appear out of nowhere when the ocean is otherwise shrouded in darkness

When the lights go out nature doesn’t stop communicating. Similar to our adaptations to cope with the dark, by making light, many organisms have developed the ability to produce light. This is called bioluminescence and is created by a chemical reaction within the organism. It is not the same as fluorescence which results from the organism absorbing light at one wavelength and then re-emitting it at another wavelength. Bioluminescence is therefore an active form of communication, whereas fluorescence is passive communication. Whilst visual light is required to observe fluorescence, bioluminescence can be witnessed in pitch black environments. It is generally blue/green in color and this is due to the shorter blue/green light waves travelling further under water.

Bioluminescence can be found throughout the ocean
It can be found in many different groups such as jellyfish, sharks, fish, algae and worms to name a few. In each group the chemical reaction that produces the light varies, which is evidence that bioluminescence has evolved multiple times. Generally, bioluminescent animals contain the chemicals required to produce light, but occasionally an animal can take in bacteria or a different bioluminescent organism that has the ability to produce bioluminescence. For example, the Hawaiian bobtail squid takes in bioluminescent bacteria which are stored in a special light organ and at night they then work together to produce light. This light acts as a cloaking device preventing the squid from casting a shadow and hence camouflaging the squid from predators.

For light to be produced organisms must contain the molecule luciferin which when combined with oxygen produces light. Different organisms will contain different types of luciferin. Some organisms can contain a catalyst called luciferase which can speed up the chemical reaction. Additionally, luciferin and oxygen can be bundled together to make a photoprotein which can be activated instantaneously when a certain ion becomes present. The intensity and colour displayed can also vary and this is very important for communication.

 
Bioluminescent animals can be found on land and in the water column, from the surface to the deepest part of the ocean at challenger deep (10,994m), and in coastal and oceanic environments. In coastal environments around 2.5% of organisms are bioluminescent whereas in pelagic environments the number is significantly higher. Studies estimate that around 70% of fish and 97% of cnidarians (jellyfish, corals, anemones and hydroids) are bioluminescent. Due to the vastness of this form of communication it could be said that bioluminescence may be the most abundant form of communication on earth. Humans see only a small portion of bioluminescence – we generally observe bioluminescence resulting from physical turbulences of the surface water due to waves or boat hulls. The aggravation of the water triggers a bioluminescent response in surface dwelling bioluminescent organisms. One of the most common bioluminescent displays observed by humans is from planktonic surface dwellers. When blooming they form a dense surface layer, which by daylight is reddish-brown in colour but at night transforms into a light display. We can see bioluminescence at Gili Lankanfushi – turn your torch off on a night snorkel and wave your hands around to disturb the water. Bioluminescence is unpredictable but the best times to observe it are when the moon is waning. 
 
Animals can light up for a variety of reasons:
to defend themselves, to procure mates and to camouflage or hunt. The dark is an unforgiving place and finding food can be life or death. Some animals concentrate their bioluminescence in a lure and dangle it around their mouths. The deep-sea angler fish has this adaptation – its lure is lit by bioluminescent bacteria. Prey are attracted to the light and can be engulfed before they realise it. The Stauroteuthis octopus which lives below 700m has replaced some of its suckers with bioluminescent cells that direct their planktonic prey into their mouth. The production of light by the cookie-cutter shark tricks whales and squid into venturing closer and once close enough the shark takes a bite out of the animal before it escapes.

Long wavelengths like red light are absorbed quickly in the surface waters and it is due to this that many deep sea animals are red – they become invisible. Additionally many organisms have lost the ability to see red light. However, the dragonfish has evolved to emit and see red light. This allows it to see red coloured prey and also they can light up the surrounding water to hunt or look for a mate.

 
Finding a mate in the dark can be a major hardship.
Flashing bioluminescent displays can be used as a signal between males and females of the same species to signify the desire to reproduce. For example, a type of male Caribbean crustacean (ostracod) lights up its upper lips to attract females. 
 
Even though bioluminescence lights up the darkness it can be used for protection and camouflage. Many animals will produce a strong flash of light to confuse predators and swim off whilst the predator is blinded. Some squid can produce bioluminescent ink – upon ejection it can stick to the predator and light it up. This can lead to the predator becoming a meal for something even larger. If a predator manages to take a bite out of a bioluminescent organism the stomach of that predator will glow making it an easy target and giving the prey time to escape
Bioluminescence can also be used for counter illumination. This is where the animal can manipulate light to prevent itself producing a shadow and making it almost invisible. They can use bioluminescence to match the light coming from the surface. This makes it almost impossible for predators below to see their prey. The lantern shark is an example of this – it can make itself look invisible by producing blue/green light to blend in with the background.
It’s surprising how any organisms create light, even in an aquarium you may notice it.
Next time you are at Gili Lankanfushi try and see the bioluminescence yourself. You never know when the next flash of light will catch you by surprise!

Carpe Diem Maldives Introduces Coral Reef Awareness Campaign in Celebration of IYOR 2018

January 2018: Carpe Diem Maldives Pvt. Ltd. begins a 12-month social media campaign to celebrate International Year of Coral Reefs 2018.

Crystal clear waters teeming with colour and marine life surround The Maldives, making it one of the most appealing and diverse coral reef destinations in the world. The new digital campaign led by Carpe Diem Maldives promotes awareness towards the status of the destination’s coral reefs. Recreational and professional divers are invited to share their underwater images through Instagram and Facebook channels using hashtags #maldivesreefawareness #carpediemmaldives and #IYOR2018 stating information to three related Ds – dive, date and depth – on each image.

2018 was announced International Year of the Reef (IYOR – www.iyor2018.org) for the third time since 1997 by International Coral Reef Initiative (ICRI), an informal partnership between the Nations and organisations that strive to preserve coral reefs and related ecosystems around the world. IYOR is a global effort to increase awareness and understanding on the values and threats to coral reefs, as well as to support related conservation, research and management efforts.

Francis Staub, International Coordinator for the Year of the Reef for ICRI states, “We welcome this initiative embracing modern media and recognising public awareness as an essential element of coral reef conservation. Campaigns such as this ensure that the general public understands the value of, and the threats to coral reefs. Furthermore, the ongoing stream of images through #maldivesreefawareness on social media channels provides marine scientists and other stakeholders around the world access to real time data on coral reefs in The Maldives.”

Regularly visited dive sites across the Maldivian atolls will be captured to show the real time reef status amidst the effects of global warming, while also recording the ongoing recovery and conservation efforts being carried out by organisations such as Coral Reef CPR. At the same time, the digital campaign encourages public engagement and general awareness to the importance of coral reefs globally.

Haris Mohamed, Acting Managing Director for Maldives Marketing and Public Relations Corporation says, “Recently awarded World’s Leading Dive Destination at the 24th annual World Travel Awards, the Maldives attracts divers from around the world to experience the beauty of our underwater marine life and reefs. This initiative by Carpe Diem Maldives highlights the conservation efforts various organisations are carrying out to ensure our reefs remain resilient and healthy for generations to come. We strongly encourage all divers to the Maldives to share their images on social media with the hashtag #maldivesreefawareness.” 

Likewise, PADI Regional Manager for The Maldives, Matt Wenger, explains “Coral reefs are among the most beautiful ecosystems on the planet and PADI works with local communities around the world to ensure that residents understand the value of their local treasure. With close to 1.2 million tourist arrivals a year to The Maldives, initiatives like Carpe Diem’s #maldivesreefawareness are so important to get the message across about the beauty of the underwater world and why we need to do everything we can to protect it. We wholeheartedly encourage all divers to participate in this simple yet effective image sharing campaign.”

The digital campaign, which will run exclusively in The Maldives until December 31st, 2018, will be promoted to guests on Carpe Diem’s liveaboard dive cruises and at the upcoming resort in Raa Atoll. Carpe Diem Cruises welcome up to 60 divers weekly across all three of their luxury liveaboard cruises. Towards the end of 2018, campaign images posted throughout the year can be submitted to a panel of professional photographers, conservationists and IYOR officials, with a chance of winning a 4-night stay in 2019 at the new resort Carpe Diem Beach Resort & Spa.

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.

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

 

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

Tourist Information

Unlike most destinations, don’t expect to find a tourist information center that will provide answers to all your questions. There is an Information Desk within the arrival area of the airport who are happy to point you in the right direction, assist you if you need to contact your accommodation provider and provide you an information booklet. They are not there, however, to organize accommodation, excursions or transfers. Once you arrive at your hotel, guesthouse or resort they will be able to offer advice on excursions and activities or check out Trip Advisor for local operators providing these services.

Transferring from the airport

Unlike other International Airports don’t expect to be able to hail a taxi as there is no taxi rank. If you have booked with a hotel, guesthouse or resort and provided them with your flight arrival details it is usual for them to send a representative to meet with you.

To reach Male independently you can choose to take the Airport Express Speedboat, the charge is MRF30 or US$2 for a one way transfer per person, leaving every 15 minutes. Or the airport public ferry, charge MRF10 or US$1 per person one way, leaving every 10 minutes. Both leave from the jetty opposite the Domestic Terminal. When you arrive in Male, just a 10 minute public ferry ride, you will be able to hail a taxi from the ferry terminal to your destination, guesthouse or hotel. A one stop drop regardless of distance is 25MVR plus an additional 5MVR per item of luggage.

To reach Hulhumale independently you can either enquire as to if a guesthouse vehicle has room on their return journey, the charge would usually be around US$10 one way or take the public bus. The airport bus departs every 30 minutes from the airport and Hulhumale on a 24 hour timetable. On the hour and on the half hour except on Fridays during Friday Prayer when there are no busses between the hours of 11:30 and 13:30. The charge is 20MVR per person one way and it is a journey of 15 minutes. Luggage is accepted and stored in the luggage compartment. At the airport the bus stop is located outside of the International departure area to the left of the food court as you face the ocean. In Hulhumale the bus stop is at the T Junction of Nirolhumagu and Huvandhumaa Higun.

Due to the location of the airport terminal it is not possible to walk to Hulhumale.

If you are transferring on to an island outside of the immediate capital area it is likely that transfer arrangements offered will include speedboat or for islands further afield a domestic flight. These methods will add a minimum of $25 per person one way dependent on distance and if the service is scheduled. Note the Maldives covers a distance of 800KM north to south. If you have done your homework it is possible to take a local ferry to many central atoll islands. These local ferries depart from one of a number of jetties in the capital Male so ensure you have allowed time to cross to the capital and locate the correct jetty.

Business Hours

It is important to know that the Maldives follows a business week from Sunday to Thursday. Most places are closed on a Friday until after Friday prayer. No public ferries operate on a Friday with the exception of those operating in the capital area between Male, Hulhumale and Villingili. These ferries also stop operation between 11:30 and 13:30 for Friday prayer.

The shops in the Maldives open at different times in the morning but usually before 09:00. Most shops close for prayer times for an interval of 15 minutes. The latest time for the shops to close business is 22:00 and cafes and restaurants 23:00.

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

This is the last part of this five part blog……

The Republic of Maldives is a Muslim country

The Maldives is a 100% Muslim country and care needs to be taken in relation to the dress code on local islands. Whilst it is acceptable for men to wear T Shirts and shorts or swim shorts; females should avoid causing offence by maintaining a more conservative approach to clothes by wearing T Shirts, loose shorts or sarongs and avoid wearing bikinis and swimwear unless on an uninhabited island, picnic island, sandbank, dive boat or resort island. Whilst the law restricts the wearing of bikinis on local islands, many guesthouses now provide dedicated tourist beaches or private gardens and sunbathing terraces.

Most hotels and guesthouses can arrange visits to nearby resorts where bikinis can be worn freely and alcoholic beverages are available. Note that resorts charge an entrance fee and access is subject to availability.

Don’t be afraid to travel in low season

With a tropical climate, plenty of sunshine and temperatures around 30°C throughout the year, there is never a bad time to visit the Maldives. There are however two distinct seasons; dry season (northeast monsoon) and wet season (southwest monsoon), with the former extending from January to March when rates will be at their highest and the latter from mid-May to November. The rare thunderstorm in the Maldives (especially around the southwest monsoon months) can be a welcome respite from the sun.

There can be heavy rain showers pretty much any time of year, but they tend to be short and cannot be accurately predicted seasonally (in other words – don’t worry too much about them – you will quite possibly experience some rain showers, but the majority of the weather should be great, and you will be unlucky to get several consecutive days of heavy rain).

Diving is good all year-round, although a basic rule is that reef life is more varied and visibility is better on the western side of any atoll from May to November and on the eastern side of any atoll from December to April.

As the Maldives is situated so close to the equator it is possible to burn even on a cloudy day and sun screen should be applied as a matter of course.

For those travelers who are looking for a helping hand to arrange a budget trip to the Maldives, require advice on which island or guesthouse to choose or want to experience more of the cultural elements of the Maldives the Secret Paradise team are just an email or phone call away!

Coral fluorescence at Gili Lankanfushi

Are corals a shining beacon at night? Corals are not just a wonder to observe during the day, at night they glow. This isn’t just for our viewing benefit; it plays a vital role in the long term survival of coral.

Fluorescence of Porites cylindrica

Due to the richness of life they create, corals are often described as the rainforests of the ocean. Their structural complexity supports one of the world’s most productive ecosystems providing ecological diversity and outstanding beauty. The coral animal (polyp) co-habitats its calcium carbonate skeleton with photosynthetic algae called zooxanthellae. These algae harness energy from solar radiation and provide the polyp with 95% of its food. Coral is therefore limited to the habitat range of the algae, which in turn is limited by the penetration of the suns ray into the ocean; both the intensity and spectral diversity of light dramatically decreases with increasing depth. Although the blue/green portion of sunlight reaches depths of around 200m the algae requires the higher light levels found in the upper 30m of the ocean. Corals are therefore limited to the upper portion of the ocean; aptly named the sunlight ocean.

The corals exposure to high light levels is crucial for its survival, but this is not without consequence. The high light intensity that corals are subjected to everyday can damage coral and zooxanthellae – similar to our skin and sunburn. Shallow water corals have a solution to this: fluorescence. The coral contains special pigments (green fluorescent pigments (GFP) and non-fluorescent chromoproteins (CP) which act as sunblock. The fluorescent pigments are in particularly high concentrations and contribute to the beautiful rainbows of colours which can be observed on the reef. When the coral is subjected to high sun exposure the pigment concentration increases, hence limiting the damage experienced by the algae when under stress from sunlight. The pigments are also involved in growth related activities, including repair. Injured coral will produce colourful patches concentrating these pigments around their injury site which prevents further cell damage. Some corals have been found to distribute fluorescent pigments around their tentacles and mouth to attract prey.

 

We are able to observe the fluorescent pigments when corals are illuminated at specific wavelengths (generally blue light). In high pigment concentrations corals can become shining beacons at night. Light is absorbed by the pigments and then re-emitted. During this process some energy is lost resulting in a different colour being observed – generally green. During our blue light night snorkel it is possible to see corals glowing on the house reef at Gili Lankanfushi.

It is now widely accepted that fluorescent pigments aid in sun protection, so why do corals below 30m still have these pigments? In shallow reefs generally only green fluorescence is observed, whereas in the mesophotic zone (between 30 – 100m) corals shine green, orange, yellow and red. Fluorescent pigments are energetically costly to create, therefore the pigments must have a biological purpose, or else they would not exist at this depth. A study carried out by the University of Southampton found that deeper corals produce fluorescence without light exposure, which suggests that these corals are not producing pigments for sun protection. It is suspected that the corals are producing pigments to transform short light wavelengths received into longer wavelengths to enhance algae photosynthesis, thus producing more food for the polyp. It has also been suggested that it may link to behavior of reef fish, although more studies are required. Next time you are night diving take a look. Harnessing these fluorescent pigments could pose significant advances for medical, commercial and ecological purposes.

Marine biologists at the Scripps Institution of Oceanography at San Diego have suggested that monitoring fluorescence could be an easy and less invasive way to monitor reef health. Scientists measured the fluorescence levels after corals were exposed to cold and heat stress. The levels were reduced when exposed to both stresses, although coral subjected to cold stress adapted and fluorescence levels returned to normal. Corals subjected to heat stress lost their algae and starved. Therefore, if high fluorescence levels are observed it suggests that the reef has a healthy coral population. Additionally there are many medical benefits that can be gained through the understanding and utilization of coral fluorescence. 

 

There are promising applications for biomedical imaging, for example pigments can be used to tag certain cells e.g. cancer cells which can then be easily viewed under the microscope. The fluorescent pigments also have the potential to be used in sun screen. Fish feeding on coral benefit from the fluorescent pigments which suggests that the pigments move up the tropic levels (food chain). Senior lecturer from King’s College London and project leader of coral sunscreen research, Paul Long and his team have suggested that if the transportation pathway up the food chain is identified it may be possible to use this to protect our skin against UV rays in the form of a tablet. This could a break-through in terms of reef safe sun screen.

 

Next time you are night snorkelling shine a blue light on the corals and view this natural wonder yourself! 

PADI’s guest blogger Emma Bell introduces herself:

I am a marine biologist and scuba diver from England. I have had the privilege of working in Greece, Seychelles and Maldives. I have worked in an aquaculture research centre where I focused on hormonal manipulation of a pelagic fish species. In addition, I have experience with coral restoration projects including frames and ropes; habitat restoration – crown of thorns, drupella and invasive plant species removal; educational activities and social media updates including blogs. I have also monitored population dynamics of bird, turtle, shark and cetacean species to aid in their conservation. I started my career working in the Maldives and I have done a round trip via Greece, England and Seychelles, I hope to increase my skills set and knowledge further whilst I am at Gili Lankanfushi, Maldives.

 

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

This blog has several parts, next week read about general tourist information……

Tourist Information

Unlike most destinations, don’t expect to find a tourist information centre that will provide answers to all your questions. There is an Information Desk within the arrival area of the airport who are happy to point you in the right direction, assist you if you need to contact your accommodation provider and provide you an information booklet. They are not there, however, to organise accommodation, excursions or transfers. Once you arrive at your hotel, guesthouse or resort they will be able to offer advice on excursions and activities or check out Trip Advisor for local operators providing these services.

 

Transferring from the airport

Unlike other International Airports don’t expect to be able to hail a taxi as there is no taxi rank. If you have booked with a hotel, guesthouse or resort and provided them with your flight arrival details it is usual for them to send a representative to meet with you.

To reach Male independently you can choose to take the Airport Express Speedboat, the charge is MRF30 or US$2 for a one way transfer per person, leaving every 15 minutes. Or the airport public ferry, charge MRF10 or US$1 per person one way, leaving every 10 minutes. Both leave from the jetty opposite the Domestic Terminal. When you arrive in Male, just a 10 minute public ferry ride, you will be able to hail a taxi from the ferry terminal to your destination, guesthouse or hotel. A one stop drop regardless of distance is 25MVR plus an additional 5MVR per item of luggage.

To reach Hulhumale independently you can either enquire as to if a guesthouse vehicle has room on their return journey, the charge would usually be around US$10 one way or take the public bus. The airport bus departs every 30 minutes from the airport and Hulhumale on a 24 hour timetable. On the hour and on the half hour except on Fridays during Friday Prayer when there are no busses between the hours of 11:30 and 13:30. The charge is 20MVR per person one way and it is a journey of 15 minutes. Luggage is accepted and stored in the luggage compartment. At the airport the bus stop is located outside of the International departure area to the left of the food court as you face the ocean.In Hulhumale the bus stop is at the T Junction of Nirolhumagu and Huvandhumaa Higun.

Due to the location of the airport terminal it is not possible to walk to Hulhumale.

If you are transferring on to an island outside of the immediate capital area it is likely that transfer arrangements offered will include speedboat or for islands further afield a domestic flight. These methods will add a minimum of $25 per person one way dependent on distance and if the service is scheduled. Note the Maldives covers a distance of 500KM north to south. If you have done your homework it is possible to take a local ferry to many central atoll islands. These local ferries depart from one of a number of jetties in the capital Male so ensure you have allowed time to cross to the capital and locate the correct jetty.

Business Hours

It is important to know that the Maldives follows a business week from Sunday to Thursday.  Most places are closed on a Friday until after Friday prayer. No public ferries operate on a Friday with the exception of those operating in the capital area between Male, Hulhumale and Villingili. These ferries also stop operation between 11:30 and 13:30 for Friday prayer.

The shops in the Maldives open at different times in the morning but usually before 09:00. Most shops close for prayer times for an interval of 15 minutes. The latest time for the shops to close business is 22:00 and cafes and restaurants 23:00.

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

This blog has several parts, next week read about general tourist information……

Currency Exchange

The Maldives has a non-convertible currency – Maldivian Rufiyaa – this cannot be purchased beforehand. One Rufiyaa is 100 Laari and is available in 500, 100, 50, 20, 10 and 5 Rufiyaa notes. The US Dollar is accepted as legal tender throughout the Maldives. Should you arrive with no USD$ then other major international currencies can be exchanged at the Bank of Maldives Foreign Exchange counter located in the arrival hall. This is the only dedicated foreign exchange counter in the Maldives. It is advised not to exchange currency in Male where bank queues are common and waiting time lengthy.

Only major foreign currency will be exchanged for local currency MVR. Hold on to your exchange receipt as you will need to present this upon departure at the exchange counter if you wish to change local currency back to foreign currency.

Paying in USD$

One US Dollar is equivalent to 15.42 Rufiyaa. However, the exchange rate offered on US$1 and US$5 notes by local businesses may be lower.This is because there is a 3% handling charge made by the bank on the deposit of US$ notes of US$5 or less.

The banks in the Maldives are very particular about the condition of bank notes and will refuse deposits of old style US$, even though still an active currency, damaged notes, badly creased, well-worn, or defaced notes will also be rejected. Therefore, if presenting such a note as form of payment you may be requested to change to a note of better condition. Please do not take offence, it is purely that the note will have no worth to the individual to whom you are paying.

Generally, any change given on a purchase made in US$ will be given in local currency MVR.

ATMs and Credit Cards

Most banks represented in Malé provide ATM services. The Bank of Maldives has several branches in Male as well as other major population hubs such as the Male International Airport, Hulhumale and Gan. Several other regional banks also operate in central Male, including the State Bank of India, Bank of Ceylon, and HSBC. There are no banks on resort islands nor on many local islands. Only local currency MVR will be dispensed from ATMs. There is an ATM at the Male branch of the Bank of Maldives dispensing US$, however, it only dispenses to Bank of Maldives cardholders.

All major credit and debit cards can be used at resorts, hotels and many shops and restaurants in Male as well as on local islands. Note however, that a credit card payment fee may be applied to the total value of your bill. This charge can fluctuate dependent on the credit card payment processing company and may be up to the value of an additional 5%.

Local Tax

All services directly related to guests will incur 10% service charge and 12% T-GST (Tourism Goods and Service Tax). The 10% service charge is applied to the total value and 12% T-GST applied to the total value + service charge.

On local islands GST (Goods and Service Tax) is imposed on the value of goods and services supplied by a registered business such as a local café, local restaurant or local shop.

Environmental ‘Green’ tax will be applied to all stays in accommodation registered as a hotel, resort or liveaboard from 1st November 2015. This adds a further US$6 per person per night and is not subject to T-GST/GST.

From October 2016 $3 will be charged per person per night for guests staying on local islands in guesthouses.

Always check the small print online or ask if it is not clear to ensure that all appropriate local tax is included. What at first appears to be a great deal may not turn out to be.
