diving in sangalaki, indonesia, 16-23 July 05

travelled 12 hours from singapore to get to a pretty obscure place in indonesia in search of manta rays. expected a school of them dancing above me, which was common in this place. but nature was so unpredictable...

like when we set off on monday for a trip to another island, Kakaban, 1.5 hrs away from Nabucco where we stayed, it was sunny. next thing we knew, we had hit right into a storm with crashing waves. our little speedboat rocked so violently, i swear we all thought it may capsize, but nobody said a word of it, of course, lest it became a prophesy come true. the precariousness of the situation gave us all sudden newfound dexterity in suiting up in our wetsuits in a split second, while the boat was swaying. i had my eye on my mask and fins in case we had to jump ship. water had flooded into the boat and the engines were wet and refused to start. the boatman was fixing it and after a long consideration, our divemaster, putu, told us, sorry, we have to cancel the trip. our crazy boatman thought otherwise though and said we would be able to make it. the engine was fixed and soon, we were speeding through the 1.5m high waves again. after crossing the rough open seas, we entered into a calm sheltered bay at the island of kakaban. the light rain created a pattern of circles on the flat sea and the dead calm seemed surreal. we hit the cold waters and surveyed the deep walls covered with a myriad of corals. the colourful fishes went about their usual business, seemingly oblivious to the storm above.

kakaban was famous for its jellyfish lake. there were four species of stingless jellyfish, including an 'upside-down' one which could be found lying on its back in shallow parts of the lake. this exposed its symbiotic algae to sunlight, enabling it to make food. it was pretty cool swimming among those jellyfishes and molesting them, knowing that they wouldn't sting. the brackish water smelt a little stale and fishy though. kabs was a little freaked out cos she had been badly stung by jellyfish before but she finally jumped in and was immediately cured of all fears i think. putu picked a jellyfish up and threw it in our direction as a joke but it broke into two, with the legs detached from the head and we were shocked and there was awkward stunned silence for a second. it was pretty funny that the joke fell flat literally and we didn’t know whether to laugh or feel sorry for the jellyfish who lost his head. apparently, there is another smaller and not so famous jellyfish lake in maratua itself. but it is harder to trek in because there are no nice walkways.

after having lunch on the beach, we dived at barracuda point at the western tip of kakaban. currents were strong and we had to descend together immediately upon hitting the surface of the water. we emptied the air from our bc's and did a synchronised negative entry on the count of three. the sense of danger of getting swept away by the currents and losing the group if we did not descend quickly enough caused the adrenaline to flow. i like 'synchro diving' already! we drifted along at 30m depth and passed barracudas, jacks, and a whitetip shark along the way. it was around kakaban that kabs lost her mask and snorkel after surfacing...

the other day trips we made were to sangalaki. we had set off on tuesday in high spirits, anticipating a huge school of mantas. however, it was all quiet when we reached the dive site, Manta Run and we wondered where the mantas have gone to. at the surface, one manta with white belly and of about 2m wing span came near our boat to check us out. we were really excited and hit the waters immediately. during the dive, he had disappeared though and just as we were giving up hope, the beautiful creature swam by gracefully, flapping his wings slowly like a bird in slow-mo across a stretch of fine, white sand. on a separate day, we saw another larger manta with a black belly. i finned to keep up with it but it was way too fast. I only got to about 2m away from it.

we also spotted sleeping leopard sharks and one 3m nurse shark at sangalaki. cheng went very close to one of the leopard sharks (which had a remora attached to it) and it woke up and swam towards bonz, who froze and quivered behind her camera. it went to about half-metre away from her and then turned away.

the other high adrenaline dive was at the channel at maratua, called Big Fish Country. when the tide was coming in and the current was at its strongest, we could see eagle rays, dogtooth tunas, school of barracudas and jacks hunting. using reef hooks to hang on, we stopped to watch the action as the current rushed past us. at the end of the dive, the current swept us into the bay of maratua.

was quite disappointed with the dives generally because our high expectations were not met – e.g. school of mantas in v-formation, somersaulting, hammerheads, etc.

well, what made up for it was the very nice resort we stayed in (with stairs leading down to the water), the very good food complete with fierce dabu dabu (indonesian style cut chili with tomato and lime) and a cute divemaster.

verdict is that nabucco is worth going back for, with or without the mantas.

reefwalk at labrador 9 jul - part II

what's eating sea grape - part II

more lucid now after a good night's sleep...

the nature walk was conducted at such an unearthly hour yesterday cos it was very low tide (which can be checked from the tide tables or from the newspapers). during ebb tide, the reef flat is exposed and we get to explore what can normally be seen only while snorkelling or diving.



the reef flat is covered mostly with algae and sea grass, with some small encrusting or boulder-shaped hard corals here and there, a sprinkle of soft corals, zoanthids, sponges and squirts. i dont know if it's because it was too early and they have not woken up yet (like me), but the little guys living on the reef flat were all pretty still or in hiding. guess maybe they were feeling vulnerable being exposed during the low tide and were trying to be as inconspicuous as possible. despite all their efforts, we managed to spot some of them.

and here's a lowdown on what we spotted and what they eat or who eats them:

sea hare


this slimy guy eats seaweed and algae. curls up into a ball at low tide. when he moves, looks like an overweight nudibranch.

snapping shrimp
this guy has one greatly enlarged claw which snaps loudly to create shock waves in the water in order to stun nearby victims.

onchidium sea slug

this oval guy can be found on the rock in intertidal zone. looks like he has warts all over him and eats algae and detritus.

blue dragon

apparently the blue dragon feeds on hydroids and also farms zooxanthellae in its own body. the zoox photosynthesizes and provides food for the blue dragon.

eel

somebody tried to lure him by offering the finger but he wouldnt budge...

spider conch
this classy looking guy prefers more rocky areas and reefs. feeds mainly on larger forms of algae. is yummy...

cone shells
ever since my friend described how the cone shell attacks the prey after she watched it on discovery channel, i've not touched another one. this guy has a mean harpoon with potent toxins to stun victims with. likes fish.

feather-duster worm
this beauty is a filter feeder. waves her long, feathery tentacles on her head to trap small plankton.

sea grapes
looks juicy and yummy and is in fact, eaten fresh in some countries. there have been reports, however, of poisoning caused by some species due to the alkaloid Caulerpin. don't say i didnt warn ya..

tape sea grass
a favourite of dugongs. their flowers are white and very small. must be so small that i cldnt spot any.

red seaweed Gracillaria
can be used for making agar-agar. my dad actually brought a bunch home one day, cooked it and refrigerated the 'soup'. true enough, it turned into jelly. but it was grey and dirty-lookin and nobody ate it. methots this couldnt be the commercial agar-agar until i searched the web...

sponge

filter feeders. the individual cells work together to produce a unidirectional current flow through the colony from which food particles are trapped. talk about cooperation!

unknown bird
there was a little brown bird chomping relentlessly on the flower buds of the coastal tree simpoh air. i don't know his name... maybe a flowerpecker?

reefwalk at labrador 9 jul - part I

what's eating sea grape - part I

survived a pre-dawn walk along the rocky shores of labrador park this morning...

waking up was the hardest part. went to bed like almost 1am the night before and when alarm (which is actually my mobile phone) rang at 5am, in a daze, i wondered who the **** called at such an unearthly hour, promptly turned it off and went back to sleep. about half an hour later, got the real call, woke up startled and after like 1 minute, suddenly realised the person on the other end of the line was my cab buddy, who's sposed to pick me up at 5.30am!

of course i didnt make it down in time to share the cab but i got there in good time. even had time to grab concealer and compact mirror and touch up while in the cab. didnt want to scare the other participants with my ghastly, pre-dawn, sleep-deprived face.

anyways, this nature walk was organised by the bluewatervolunteers to train volunteer guides for helping out in future walks for the public. the coordinator today is a pretty serious, stern guy. i got chided for wearing slippers. you know, those rubber type flimsy japanese flip-flops. ok, i deserved it cos there were instructions to wear dive booties or other appropriate footwear. the real reason was that i didnt wanna carry a pair of wet booties around with me when i go shopping after. but of course, my official reply was that i forgot to bring. my super flip-flops have brought me everywhere - jungle trekking in lazarus, up bukit timah trail, through the mud at chek jawa... oh, actually bkt timah was another pair of prettier flip-flops which broke on the way and i walked up barefoot. the feeling of damp, half-decomposed leaves on bare feet was wonderful, btw...

sorry i side-tracked. this morning's walk was very fulfilling. we saw 5 SEA HARES! the only other time i saw sea hare was during muck diving in manado, indonesia. the other highlights were a pair of mating "blue dragon" nudibranchs, commensual shrimps on a carpet anemone, a tiny eel (size of finger) and an empty spider conch. the usual suspects were there, as well - the snapping shrimps, heard but not seen.

there was much more to the guided walk than just spotting stuff, of course. in part II, will tell you more about who eats what and what can be eaten. it's just the singaporean in me, being pre-occupied with eating...

need get some sleep now... *yawn*
