Finally....

So it finally happened, the third and final nest that we have all been waiting for hatched in the early hours of the morning on the 11^th October, at 3am to be precise! Altogether 151 green turtle hatchlings crawled out of the nest.  It was amazing to watch as one by one these cute little fuzzy things emerged from the nest, a head would appear and then a body as they pulled themselves free, and then another and another, they were starting to pile up on top of each other trying to break free! They looked fuzzy as their bodies were completely covered in sand! Just thinking about it now makes me smile. 

As the moon was absent we used torches to light their way to the sea instead. They followed the light and made a mad dash for it, as they got closer they seemed to get faster as well like they sensed the ocean was close, it was funny to watch as they almost skipped and jumped themselves to the sea. It is widely believed that hatchlings imprint the unique qualities of their natal beach while still in the nest and/or during their first trip from the nest to the sea. Therefore it was important that we let them run down the beach to the sea. Otherwise they might not know how to return back to the beach to nest when they are adults. As they entered the water we collected them all and then we will release them in a few days on the outside of the atoll were hopefully they will have a better chance of survival. Although the majority of them will probably perish, hopefully one or two will make it to adulthood and then return to Reethi Rah in the future to lay more nests. This is a remarkable fact about sea turtles. They will always return to the lay their nests on the same beach were they were born decades before. Although i think i might have mentioned that before!

I finally got back to bed at 630am but I couldn’t sleep as I was so wired from what had just happened. I just got to witness one of nature’s incredible events, words can't quite describe it, it was amazing, beautiful, and almost quite surreal (probably because of my lack of sleep) but it was definitely something that I will never forget! Out of the many photos I took I have uploaded some of the best ones to share with you. Even though you weren’t there to see this I’m sure these photos will make you smile, 151 cute baby turtles, who couldn’t not smile! Enjoy and hopefully next year we will get to see it all over again! 

             

False alarm

This morning I woke up from the sound of the rain, it was 5am and the first thing that popped into my head was the turtle nest!!! Hatchlings will sometime emerge from the nest in a rain storm you see and this is what happened with the last nest so I thought I better check just to be sure.  But thankfully its not happening yet…. I got to the nest and there was no movement. This I was quite glad about as it was proper tropical rain and trying to do anything in that would have been hard and very wet!  So now I find myself wide awake at 530 in the morning!! Is this a sign of the next week to come, god I hope not, or im going to be one tired marine biologist. Security are patrolling the nest at night but I am so worried they might miss it and I will come to the nest one morning and all the hatchlings will be cooking in the hot sun as they were unable to get out of the enclosure. Can you imagine….. marine biologists cooks 100 turtle hatchlings in the hot sun!!!! hmmmm, not good.  Obviously this wont happen but you could say its my little turtle nightmare!!! So the count down continues…..

Unexpected guests...

On the 1^st October Reethi Rah was greeted by some unexpected and very cute guests…….

A turtle nest that we did not know about hatched in the early hours of the morning on Turtle beach. Nearly all of the hatchlings made their way into the lagoon to start their lives at sea. However most of their lives would have been very short-lived. Only 2 inches in size they make bite sized meals for all the fish and sharks waiting in the lagoon to gobble them up, a sad fact of life as only 1 in a 1000 hatchlings will make it to adulthood!!

However, although I was very gutted to miss this event and unable to try and save the hatchlings from their ultimate doom the gardener did manage to find 5 of these little guys and bring them to us at recreation. We plan to keep them for a few months and then release them into the wild when they are slightly bigger so hopefully they have a better chance of survival. But it doesn’t stop here…..

Again on the 4^th October yet again another nest that we did not know about hatched on Turtle beach and again 100 or so hatchlings followed the light of the moon into the sea, and again most of them or all of them ended up as breakfast! Whether both these nest were from the same adult female turtle we do not know. Usually they have 10-14 day intervals between laying nests and as this was just a few days it may well have been a different turtle. One little hatchling from this nest however was found in the bushes so he obviously got lost on his way to the sea. Lucky for him though, his bad sense of direction has saved his life, as our 5 little hatchlings now become 6.  Hopefully our protected nest is due to hatch in the next few days and if all goes to plan we can collect all the hatchlings from this nest and release them the next evening on the outside of the atoll. Although the majority of them will probably perish hopefully one or two will make it to adulthood and then return to Reethi Rah in the future to lay more nests. That would be very cool. For now I am on countdown until nest 3 finally decides to pop! Three nests on one beach though, how fantastic is that and hopefully the same green turtles will return next year to lay more nests and maybe next time we will see them coming……..

Green Turtle Nest at One&Only Reethi Rah

When I arrived back to the island from my vacation in Thailand there was some exciting news waiting for me. A green turtle had come and laid a nest, on Turtle beach of all places. How fantastic :)

Worldwide, there are only 8 species of turtles, 5 of which are known to occur in the Maldives; the Leatherback turtle, Loggerhead, Olive Ridley, Green and Hawksbill turtle. Turtles are actually marine reptiles and they must come to the surface to breathe. They spend their entire lives out at sea only returning to the land to nest. It is quite remarkable as they return back to the same beach were they were born decades before! Scientists believe that they use the Earth’s magnetic compass to navigate back kind of like a GPS but this is still yet to be proven. Still very cool though!

The Green and Hawksbill Turtles are the most common turtles in the Maldives and nest frequently throughout the islands. Green turtles nest at intervals of 2, 3 or more years. During a nesting season they will nest 3 to 5 times and lay on average about 115 ping pong like eggs in each nest.  The hatchlings hatch about 60 days after the eggs have been laid and usually emerge from the nest in groups at night. They will orientate themselves with the brightest light, which is the reflection of the moon on the horizon, and make a mad dash for the ocean. If they don’t make it to the ocean quickly many hatchlings will die from predators like birds and crabs, and then also sharks and big fish once they enter the water. In fact, only one in a thousand will survive to adulthood and this is just from natural factors!!!  Pretty crazy stuff.

Unfortunately, it doesn’t stop there; every species of sea turtle is actually listed as endangered or critically endangered by the International Union for the Conservation of Nature (IUCN), and like most things in this world, it is due to human threats. Turtles are harvested for their meat and for their shells, they are made into turtle curry or soup, into bracelets and sunglasses. In addition to this direct harvest, turtles are also captured in fishing nets and lines, which results in the death of tens of thousands of turtles annually. These are just of few of the threats facing turtles, there are many more but I don’t want to depress you too much! In the Maldives there has been a ban on the catching of sea turtles since June 1995, but sadly catching and killing turtles does still happen on some of the islands. A bigger problem is that there is no ban for the collection of turtle eggs which continues to happen through the Maldives. It is therefore of utmost importance to protect nesting beaches from the exploitation of eggs as well as creating awareness about this and the importance of protecting turtles. These ancient marine reptiles have been around for a 100 million years and we want to keep it that way for another 100 at least!

The nest at Turtle Beach has been protected with an enclosure and do not disturb sign. I am expecting it to hatch any day soon, actually that’s not entirely true, as the hatchlings will emerge in the early hours of the morning. It’s going to be a very long night but definitely worth it as this is my chance to witness one of nature’s unique and incredible events. What an amazing opportunity and how lucky for me that’s it’s happening right on my doorstep, whoop whoop. The countdown begins so watch this space…..

Welcome to the Maldives.... 1192 coral islands!

So I though I should explain a little bit about the country were I am working...

For those of you who don’t know, the Maldives lies in the Indian Ocean just South West of Sri Lanka and India. Spread over 90,000 square kilometers, and stretching about 900km from North to South, the Maldives is actually a country that is mostly made up of ocean, 99% ocean to be precise. So now you know why I came here! A dream come true for a Marine Biologist. The remaining 1% comprises 1192 coral islands which make up the 26 atolls of the Maldives.

So what is an atoll I hear you all asking. The word atoll itself actually originated from the Maldivian language known as Dhivehi. How atolls are formed is very impressive and worth explaining so here goes, i will try and be brief! According to Charles Darwin, the Maldives is part of an underwater mountain range that stretches 2000km. He hypothesized that shifting tectonic plates caused volcanic islands to erupt from the ocean floor. These resulting volcanoes became dormant providing the perfect place for reef building corals to come and grow.  As the volcanoes began to submerge back into the ocean floor, the corals continued to grow upwards towards the light. Eventually all you are left with is an outer ring of coral reef enclosing a shallow lagoon. And that is what an atoll is, fascinating stuff!!! I’m not quite finished though as there is a slight ongoing debate about how the Maldivian atolls were formed. The other theory is that layers of coral reef actually built up on top of the underwater mountains and gradually grew to the surface. As the sea level rose and fell due to glacial melts the corals also grew up with the sea level rise and eroded away when the sea level fell. The highest and hardest corals on the outer edge remained forming rings while the weaker corals in the centre broke down.

Within the atolls are strings of islands and sand banks which have been formed entirely from broken corals which have been eroded over time. Each island has their own unique reef were you can find countless colourful fish and vibrant corals.  Every atoll also has deep channels dividing the outer coral reef ring. These channels were created over the years by tides and storms. Strong currents flow in and out of these channels twice-daily bringing an influx of nutrients and oxygen rich waters which keep the lagoon alive.  Not to mention all the marine animals; turtles and dolphins shelter in the lagoon during the day while manta’s and sharks migrate in and out following the currents and the flow of food.  It’s an underwater haven, another world entirely!

So in a nutshell this entire country has been built up from coral reefs. It is the sixth largest reef system in the world containing 3% of the World’s total reefs!!! Ok enough with the scientific explanations. How can I best explain… the Maldives is simply tropical paradise, if you’re a diver then it’s a place not to be missed. Even if you don’t dive, it’s a place not to be missed! As well as the sheer beauty of the place, it’s a geographical marvel. Out of the 1192 islands only 200 are local islands and 130 are resort islands.  That leaves about 850 uninhabited islands surrounded by 99% water!!! For me it’s like being on a permenent postcard…. That’s what I first thought when I stepped onto one of these small islands were the sand was so white and so fine. I was surrounded by clear turquoise waters and beautiful reefs, and all I could see for miles were other small islands dotted in the distance. It was breathtaking. I couldn’t quite believe what I was seeing or were I was. Unfortunately now after being here for nearly 3 years I am getting quite accustomed to these beautiful views, I almost take it for granted. I have to keep reminding myself how lucky I am to be here! However, beauty may come with a price.... The Maldives is actually the lowest country in the world. The islands lie on average only about 1.5m above sea level with the highest point being only 2.4m!! So the question everyone is asking is will the Maldives still be here in say the next 100 years or will the islands disappear beneath the waves? Will global warming and sea level rise take its toll?? Well that’s a whole other story which I will blog about some other time…….. For now enjoy some of my favourite photos which will hopefully convey the beauty of the Maldives as I see it :)
