Stalking a Blue-tailed Dartfish 2 Jan 2013

Zee and Debby have a paper out in Nature in Singapore, documenting the observation of a new fish record for Singapore: the Blue-tailed Dartfish (Ptereleotris hanae). Check out the video link the electronic version of the paper, showing a pair of them at Palau Hantu. A really beautiful fish, but shy and elusive; up till Zee asked me for a still image of the fish, the video was our best record for its occurrence in Singapore.

I’d seen the fish twice before at Hantu, once at the western side, and once at the northern tip near Bukom; both times, I didn’t get a useable image – being a particularly shy fish, getting up close and personal with it was very difficult, and the sediment in the water made long-distance shots almost impossible. The third time was the charm though, because this time, the fish was out and about, apparently busy feeding on plankton. After several attempts at long-distance (long distance here meaning more than 1.5m away) proved unsuccessful, I decided to just acclimatize the fish to my presence by just hanging around its feeding range, and trying my best to look busy taking photos of anything else except the fish. The ruse seemed to work (or maybe it was just very hungry!) – after about 15mins (and my inching in about half a meter), the fish seemed to ignore me and my buddy’s presence.

Taking this once-in-a-blue-moon opportunity, I happily snapped away before cold and lack of air ended our encounter. Of the 2 dozen or so images I took, only about a quarter of them turned out to be useable, and the best one was chosen for the paper.


Yay! 😀

Noteworthy fishes of Singapore 18 Feb 2009

I managed to get a paper (article 12 on the list) published in “Nature in Singapore“, and e-journal edited and published by the Lee Kong Chian Natural History Museum (formerly known as the Raffles Museum of Biodiversity Research). It documents 5 fishes recorded in Singapore that we’ve seen during surveys of the coral reefs. Three are new records, namely the titan triggerfish, Janss’ pipefish and humphead bannerfish. Of the remaining two, the polka dot grouper had not been observed live by divers locally, although two specimens exist in LKCNHM; the banded goby was previously reported by other researchers, but strangely, no specimen or photograph exists of it, until now.

It still amazes how much our marine environment, just a stone’s throw away from where most of us live, still harbours such beauties. Makes me wonder what else is out there.

Other “new” finds …. Lots of nudi’s at Colourful Clouds blog; sea stars on the Wild Shores blog and many more, I expect.

Eagle rays! 3 Feb 2009

Another “shark” photo … ok, strictly speaking not a “shark”, but close enough 🙂

These six eagle rays were cruising through a channel at Gam, Rajah Ampat, at about 10m of water. I had to swim perpendicular into the strong current to get the middle of the channel, and just in front of the school. Then, I had to face into the current (so that the rays were in front of me) and just went along with the flow of the current, to get this shot. Water wasn’t very clear – we were plagued by sedimented waters throughout our 10-day stay there.

Sneaky guitar ray 3 Feb 2009

Inspired by Southern Fried Science, I thought I’d post some of my “shark” shots. Here’s a funny one.

Guitar ray!!

I was on a live aboard to 7 Skies wreck and we had stopped by Kuantan Wreck. A couple of divers who had been here before were eager to be the first in the water to catch sight of a guitar ray, which they claimed would be scared away by the crowd of divers if they didn’t get in first. So off they went, with my following leisurely behind. And Lo! there was the guitar ray, which was hiding in a crevice in the wreck, that the first two did not see! As it streaked out of it hidey hole, I managed to snap one picture (on my trusty point-and-shoot Canon S50) of it sneaking past the divers in front 🙂

Mola Magic!! 17 Oct 2006

Mola-molas (or sunfish, as they are also known) have been on my list of fish to see for as long as I can remember, right alongside all the other big stuff like whalesharks, mantas etc. So it was with mixed emotions when I heard of people sighting 5, 6, 7 molas in dives in Bali. Previous experience had warned me that I might go and hear those dreaded words “… you just missed them … there were 7 of them here last week …”. However, I put those thoughts behind me … and prepared suitable protection for me and my monster baby for mola hunting on the 21 and 22 Sep 2006.

I was filled with nervous excitement as I prepared to enter the 20 degC plus water, with my monster baby in tow, to catch a glimpse of these strange giants. “The water looks good.” our guide, Menyun said. “Upwelling of cold water and the surface is calm … should be cold, but currents will be ok … and we are the first ones here!”

Menyun, our guide for the day

Indeed, we (Eunice and myself) were up at 6.30am for a bit of breakfast, before loading up onto Bali Scuba’s van at 7.30 for a short drive to the beach, where the boat was moored. There, we were joined by David, Bali Scuba’s owner – who had some new “toys” to try out. A small skiff brought us to he speedboat, where all our gear was already loaded up.

As we headed out, we were amazed by the surf breaking about 400m offshore … No wonder Bali is a surfer’s paradise, if the surf was this big on a relatively calm day! Once through the break in the fringing reefs, we were off, our twin 250hp engines shooting us through the 2m high swells towards Crystal Bay in Nusa Penida, off in the hazy distance.

The first clear sight of Nusa Penida was dramatic – waves crashing against its sheer cliff faces, bringing to mind the axiom “an immoveable object meeting an unstoppable force”. Then around the bend, the sheltered Crystal Bay … with a beach! We were the only boat there, but not for long, Menyun assured us. We geared up quickly and plunged into the chilly water. What would we see? Would I come up disappointed? More importantly, would I get any good photo?

I flashed back to the time on a liveaboard in the Philippines when my group saw a mola at Apo Reef – never seen there before, the veteran guides had told us. Three cameras, one video cam, but we only managed one hazy, blurry photo of the mola swimming away from us. Murphy was really busy that day as one of the divers had her macro lens on, the other’s camera didn’t work and the video cam decided to go on a holiday. And me, slow to react as usual, managed only one shot before the fish vanished into the deep.

Back to the chilly present, I was glad for my 6 mil suit, hood and gloves that kept most of the cold out … that is until we hit the thermocline at about 20m – my dive computer showed 23 degC (down from 25) but it must have been at least 19! The cold literally took my breath away, and I was afraid with all the huffing and puffing I was doing, I’d run out of air and miss the show. Not to mention my depth was beeping and flashing, indicating my impeding exceedence of my normal dive limits.

All suited up and no where to go but down!

And then, in the blue … the unmistakable shape of the mola! Trying to remain calm, as we were told, so as not to startle the fish, we breached 45m for our first clear view of this amazing giant. It was in the typical face-up position it assumed for cleaning, with the schools of butterflyfishes and bannerfishes and the odd angelfish, pecking frantically at its skin for parasites.

So mesmerized by my first clear sighting of a mola, I vaguely noticed Menyun pointing behind the fish …. to another 3 mola lined up in a row in the same face-up position!! Trying not to scream in excitement, I (very calmly, I thought – but it could just have been the nitrogen talking) took a few pictures of the first mola and then proceeded to ascend slightly to try and get the 4 molas in a frame. No such luck as they were too spread out, and the nearest one was beginning to look nervous. Still, I managed to get 3 in a frame, which, now thinking about it, was quite amazing, given that I had to make split-decision thinking at about 45m to reset my camera settings in rapid succession to get the shot.

More-lah molas!!

We finally had to ascend to begin our decompression, elated, but craving for more. On our way back, we saw the 2nd batch of divers (about 5 in the group) heading in the direction we had come from. On the surface, the once empty cove now had 5 other boats with their divers getting ready to enter the water. We could see 4 more steaming in, and Menyun said that as many as 20 boats could be at the site! Wow … that’s about 100 divers in the water looking for molas on a crowded day!

Regardless of the crowd, I now had some pictures in the bag, and was eager to get more. Menyun’s plan was simple … come early, and be the first on the water for each dive, while the others were still finishing up their surface interval time … brilliant! We spotted 5 more molas in our next 5 dives – 3 more on the second dive, but none on the third, as the waters were getting warmer. The cold upwelling currents had gone, taking the molas with them. The next day’s diving was not as exciting as the first, as the upwelling currents didn’t start till the second dive, and only 2 molas were sighted, one each on our second last dive and last dive. We would have had a better session on our last dive with the mola if a diver from another group hadn’t gone rushing up to it and spooked it away. *Sigh* … humans!

With the number of divers and boats coming to this tiny part of the island, one wonders if this activity is sustainable, or if it harms the molas … being cautious divers, we *try* to keep a respectable distance, but our strobes would undoubtedly cause some disturbance to the behaviour of these animals. In the other extreme, impatient divers who rush up to the mola for that “once-in-a-lifetime” shot would cut short their cleaning … leading to who knows what effects? Even the shear number of divers in the water all bubbling away, is probably enough to scare these gentle giants away.

A wall of bubbles – a scary sight, and no doubt a scary sound as well, to the fish

While there is probably no shortage of cleaning stations – Menyun says there are even bigger molas on the other side of the cove, but the currents are so strong it is almost impossible to dive there – it is likely that Crystal Bay will become less of an attraction to the fish if the disturbance continues for a long time. I guess only time will tell.

Man-mola … mola-man?
