I’m sure some of you who couldn’t make it for this dive have been wondering how much you’ve missed. The consolation is that you didn’t miss the coral spawning, but you still missed on some truly incredible night diving! (Above: Anemone with ascidians)
Marine biologist Jeffery Low was the unofficial scientific officer for this dive, which was also advised by Karrene Tun, another biologist who recommended the day for our dive. Karrene had been monitoring the development of egg sacs within the coral in specific sites in Singapore, and will be conducting certain experiments to better understand the reproduction of corals and the environmental factors that threaten or support them. (Above: Sleeping fish)
We set up 4 transects along the fringing reef and assigned a pair of buddies to work along each 20m transect. The point of the transect was simply to avoid double counting any corals that had spawned. So each buddy hung out and of course they didn’t just twiddle their thumbs as they indefinitely waited for the corals to spawn! With some of the most advanced spotters the Blog has ever encountered, camera flashes were ablaze across the reef as some of the most minute to some of the truly largest creatures on the reef were being photographed and observed! (Above: Octopus)
The night began with our encounter with Betsy the large hawksbill turtle as I posted yesterday. She truly is a large one and this time we weren’t just guessing! Because she was lying right next to the transect tape we were literally able to measure her up! From head to base of carapace, she measured about a meter! Her shell was covered with algae and freckled with barnacles. I’m blown away just thinking about how old she might be and the changes she must’ve witnessed and experienced as a turtle living in Singapore. Did she get a chance to mate? Did she ever return to shore to lay her eggs? I wonder, I wonder… (Above: [top row] Coral crab, shrimp, swimmer crab, eight-banded butterflyfish, flatworms [bottom row] box crab, swimmer crab, decorator crab, ‘closed’ crinoid, ‘open’ crinoid)
Some things you don’t have to wonder about though, is the myriad of macro (and mega) fauna that dotted every bit of reef, which certainly bursts into a spectacle of life at night. I’ll let the following images of shrimps, crabs, tiny fish, and some amaturish videos, do the talking. The only other largish animal I encountered on the reef was the blue spotted fan tail ray, which I was too absorbed watching that I at first forgot but later decided not to document (sorry!). To understand what it’s like, perhaps you’ll have to let yourself experience it first hand… (Above: Acopora goby)
A rare find: Divers are more used to finding this Imperial shrimp riding on the backs of the Spanish dancer nudibranch. Here is finds safety in an Acopora coral.
A young Yellow-finned angelfish tries to remain safe from predators by hiding deep within this coral, but safety doesn’t come easy on the reef. Several predators look for food by creeping within the corals as well.

This year’s mass coral spawning in Singapore is estimated to fall over the next few days, from 23 - 25 April, 2008. As this period falls over Earth Day week, we’re making this dive a part of our Earth Day 2008 activities!
If you’d like to join us for this dive, you have at least be an advanced open water diver or its equivalent. You are required to have a camera and your own slate. Divers will be paired up and required to survey a designated zone around Hantu Island. Details of the spawning (should it happen! there’s no guarantee!) such as the time, depth, species, and it’s location should be recorded. This data will be collated with surveys being done in other areas of Singapore, and will help scientists in understanding the factors that influence coral reproduction in Singapore and the nearby regions.
Time: 1800 - 2200 hrs
Venue: Pasir Panjang Ferry Terminal
Cost: $95.00
Registration for this dive has closed.

DATE & TIME : Saturday 26 April 2pm – 1pm
VENUE : Function Hall Botany Centre, Singapore Botanical Gardens.
Synopsis: Pulau Hantu is one of Singapore’s most renowned Southern Islands. Despite its prominence, it is constantly left to cope with a relentlessly changing coastline and marine environment. For a long time, the threats to Pulau Hantu have avoided the scrutiny of the public and the brilliance of its marine habitat gone unheralded. Debby Ng will bring clarity to the usually murky waters of Pulau Hantu with her underwater photos and videos.
About the speaker: Debby Ng is a full-time environmental journalist. She began her work in film and moved on to television, but eventually realised that she gained the most satisfaction from communicating her concerns on the environment through her photography and writing. Her work has been published in several regional and international magazines, including the award-winning Lebanese magazine, Environment & Development. She has also worked with numerous Asian and international non-government organisations such as the World Wide Fund for Nature (WWF), and the Environmental Investigation Agency (EIA). In 2005 she assisted the Indonesian government in their assessment of fisheries, a project funded by The World Conservation Union (IUCN), the only conservation organisation with official observer status at the United Nations. Debby Ng is founder of the Hantu Blog, an education and awareness project powered entirely by volunteers and utilising free electronic media. She is also a volunteer dive guide and a freelance nature guide with Creative Kids.

While most people are waiting for April 22, Earth Day to do their bit for the environment, nature enthusiast, educator, poet, and naturalist in his own right, Joseph Lai, has already swung into action to help save local reefs a tangle at a time.
Whilst I was at ADEX on Saturday, Joseph was leading a group of young people concerned about the environment and eager to do their bit, into the intertidal reefs of Pulau Hantu to remove a discarded fishing net that had become tangled in the reef. More at Joseph’s Blog.
When fishing nets are discarded they are referred to as ghost nets, so called because they drift carelessly in the ocean, snaring all sorts of wildlife from corals to pelagic and reef animals. Because they are not degradable, these nets continue to harm marine and coastal life throughout their indefinite “lifetimes”.
Remember, you don’t have to wait for an event to do your bit for the environment. It’s way more effective to work little bits of positive acts for the environment into your daily life. But in order to amplify your actions, not only should you passively try to reduce your consumption and try to live sustainably, but you should actively reach out to others and encourage them to live the way you do.
George Monbiot is the author of the best selling books The Age of Consent: a manifesto for a new world order, Captive State: the corporate takeover of Britain, and Heat: How to stop the Planet Burning. In an interview with New Consumer he suggests…
“There is absolutely one cast iron rule and that is that you don’t [make a difference] by yourself. You have to work with other people and in nearly all cases there are already groups which you can join. Never try to precipitate political change by yourself, it’s just not going to work. The lone voice might sound romantic but it’s not effective. For this to work you will have to work with others.”
Before you get all depressed thinking about how many plastic bags you have refused at the supermarket and how this doesn’t make a difference on a global scale, remember, that BEFORE you get to convincing others or working with others, you have to begin by working with yourself. When you’re convinced of your actions, and it’s roll-on effect, only then can you convincingly incur that same belief in others. It really depends on how far along you are, but it’s good to keep Monbiot’s philosophy in mind. If you’re already in the habit of making a difference, why not expand on it and have others make that same difference? But if you’re still getting used to it, go easy on yourself and keep on working at getting that spark to transform into an endearing flame.

Thanks to Ria for posting these pictures and her comments of the local conservation outreach efforts at ADEX today (April 19)! Without her swift photo taking action I wouldn’t have the opportunity to generate this little blog!
Not only did the event allow an exchange of information between nature groups and the public, but it proved to be a great platform for networking between volunteers from various fields of environmental work.
Diversity is important in environmental protection work because it is an extremely dynamic and organic movement that truly requires the synergy of organisations and individuals in order to be effective and up to speed.
It was inspiring to be amongst other similarly passionate individuals and motivating to meet young people who felt strongly about the environmental cause! Thanks to the ADEX organisers for kindly providing an area for Eco Village and kudos to them for conceiving such a great idea!
To read more about the other groups that participated and to view all the above pictures and more, visit the Wildfilms Blog and the IYOR Singapore Blog! If you missed us today, you can still catch us tomorrow (April 20) for the final day of the expo! Hope to see you there!

Pulau Hantu’s iconic sea critter, the Tigertail seahorse, makes its North American debut at Nature Online, the Web site of the popular American public television series Nature. The series is produced by channel Thirteen/WNET New York, the highest-rated public TV station in the US, offering a wealth of programming from the Public Broadcasting Service. The non-profit corporation also operates WLIW21, public television, presenting programming and outreach projects that educate, enlighten and entertain, as well as several digital channels, and on-demand video services. Thirteen/WNET began broadcasting in 1962.
The Tigertail seahorse is part of a Web feature for an article about interesting mating antics. Follow the above link and click “See the answers” at the bottom of the page to be taken to the page where the photo is displayed!
It’s great that The Hantu Blog, a free public education service, is able to contribute to a similar outreach vehicle half way across the planet. Because Nature Online will have an enormous reach not just to people in the US but to people all over the world, we hope our Seahorse ambassador and our Blog will garner the attention that our reefs need in order to survive the next seven generations.
Free public television has been so important in the nurturing of society’s less privileged since the 1970s. In an era where everyone watches cable television, it’s hard to imagine a world without it. But a majority of society still depends on public television to have fun, learn and be influenced. The even better news is that today, there’s more information that can be freely accessed (and delivered!) than ever before. So there’s really no excuse to be misinformed anymore.

The Hantu Blog yesterday received an email from ERM, an environmental consulting agency, requesting the following information:
- average number of divers that go to the island week
- which of the areas are the most popular for diving
- average number of boats that visit the island weekly (plus number of people per boat)
Apart from explaining that their “company is conducting an ecological study for the Pulau Hantu area” they were unable and have refused to divulge further information about the purpose of the study and for whom this study is being conducted.
This was the Hantu Blog’s reply:
I understand your predicament and and sympathise with you being unable to divulge more information as much as I am unable to receive the info I want.
I can’t think of another group to refer to you as no one visits Pulau Hantu more regularly and frequently than us.
While I am unable to give you information on your questions (1) & (3) because we haven’t done such a traffic survey of the island, I’m also certain that those figures can be easily gained by monitoring the island over the next few months as these are the months of average visitorship. Visitors to the island increase during the season of the Northeast Monsoon.
As for question (2) however, the site near the former Bayan reefs, fringing the north of Hantu Kecil are definately the most preferred site for divers. We call this the North reef. This is not because of the slack current, which varies with the tide. There are times when diving at the North reef are not recommended. This goes for all the reefs that surround Hantu Island. We dive them according to the suitable tide. The North reef is possibly the most biologically diverse site, sheltering some of Hantu’s most sought after, rare and spactacular species up to a depth of 20m. You can view some of these species on our website. We refrain from mentioning the exact positions where the photographed specimens are shot to deter poachers. In addition, otters have only ever been sighted fishing the the North reef.
Another site with intense diversity is the South reef (the reef that faces south) on Hantu Besar. That site is less accessible because of prevailing strong currents but it is still dived as often as possible whenever there is a slack tide. There are some species here that aren’t found on the North reef (as there are some species in the North we don’t find in the South), and because the currents flush the area consistently the corals develop very differently from any other sites around Hantu.
Finally the reef that faces west, the Western Fringing Reef and the Western Patch Reef house their own unique fauna. A certain species of anemonefish and seaslug is found no where else. Turtles and sea snakes have also been observed to feed frequently in the area.
If you need more specific information about the species in the various areas and how tides affect diveability in the various areas, I’d be more than happy to meet with you, either on Hantu island or at your convenience. It’d be very reassuring to know that your company, which I understand to be one of the world’s most renowned, does compelling field research along with gathering data vicariously.
If your company would like a presentation of Hantu’s marine or terrestrial fauna, I’d also be happy to oblige. As much as it would be ideal for companies to value information exchange, I understand that you are a consultancy with terms not governed by you but your client. The Hantu Blog practices very much on the contrary, believing that withholding information only leads to ignorance, which is why I’m offering you this opportunity to gather as much information as you’d like on Hantu Island. It’s our job.
I’m concerned about why this information is being sought after and am particularly wary because of the manner in which the information was requested and how further details have been declined.
Together with other local NGOs, the Hantu Blog will be looking into the matter and will contact relative companies and organisations that should or might have details about the research and its purpose. I’d also encourage Pulau Hantu enthusiasts to keep themselves alert to the matter and check the local newspapers for possible developments.
To reiterate the email to ERM, the Hantu Blog exists to gather and distribute information about the island. We believe that information can empower people to make (hopefully) positive changes to safeguard our natural heritage. But there is nothing more effective and powerful than the efforts of a collective people - you. If you are concerned about Hantu, make your concerns known. Email us or contact one of the following organisations, expressing your concerns and asking for details of the study to be released.
