Komodo: the underwater laboratory



KomodoVolcanic gas bubbles were percolating from the sandy bottom below me.  Yellow particles of sulfur that had precipitated out of these gases from Sangeang Volcano, dusted the perfectly black sand, and the sand was warm to the touch.  I thought, it is a good thing that I have my underwater “safety goggles” on, as it was my first sense that in the sea in Komodo a delicate (or perhaps explosive) experiment was still in progress.  There in front of me I felt like I had an eyewitness view below the surface of the ocean to the basic ingredients necessary to cook-up life.

Komodo lies in Indonesia within the Coral Triangle, where the richest biodiversity in marine life resides.  However, Komodo probably made an unforgettable first impression on me, like most kids growing up in the Midwest, through the images of a land animal, the Komodo dragon.  I could not have imagined then, mesmerized in front of the TV, that it would be through scuba diving that I would get there.

Janice 7As a dive destination, Komodo is known for its swift currents and cool thermoclines.  Based on these characteristics, I was somewhat reluctant to dive Komodo.  Furthermore, reading about diver mishaps in Komodo, which is easy to do because of the Internet, did not settle the issue.  A culmination of a diver’s worst nightmare in Komodo was actually a true story: divers had been both swept away and had to fight off Komodo dragons after finding refuge on an island.  I am not in for that much adventure (or effort), but what I discovered, is that divers in Komodo who are most vulnerable to these incidents are the ones from liveaboards without dedicated boat tenders.  I decided then that for my Komodo experience, I would take the Seven Seas, a big boat, with an attentive crew, that is well known for establishing underwater exploration of the area as a dive destination.

KomodoKomodo, like most of Indonesia, is a string of islands created by volcanic eruptions.  To dive Sangeang early in the itinerary was a prelude to the park not only because it is a volcano, but because it also seems to set time back to the beginning.  It is particularly fascinating to me as a diver, as there is a combination of geological, geographical as well as biological phenomena to experience.  Smoke plumes surround the peak of Sangeang, but that it is active, is more easily viewed on the sea floor at dive sites like the one described above, Tiny Bubbles.  It is an ethereal place, dark because of the black rock, but clearly rich with nutrients for the plethora of vibrantly colored soft corals growing like wall hangings from the blocks of volcanic basalt.  It has the feeling of an underwater burn area where soft and whip corals flourish as do wild flowers after the spring rains following a fire.  Nudibranchs are prolific here, as is macro life in general.  The dive guides found a big-bellied red Bargi Banti pygmy sea horse, a tomezuma shrimp, and a xenocrab.

KomodoWe shifted our eyes from macro to wide angle when we arrived at Manta Alley.  Our backward roll was into an amphitheater formed of volcanic rock, and we descended to the sandy bottom at 25 meters where we remained stationary to watch the mantas overhead.  The volcanic amphitheater provides a spectacular backdrop for viewing the manta rays, and at times, I forgot that I was there to watch the mantas and not the many sessile creatures that live in these walls as permanent spectators to the graceful pelagic animals.  We viewed at least eight different manta rays, and on the second dive, the animals were even friendlier, swimming so close as if wanting to make contact.   Afterwards when I asked about how to differentiate between male and female rays (I can’t leave the scientist at home), I learned, instead, that we actually saw the two types of manta rays, oceanic and reef, and that they are distinguishable largely based on patterns of coloration.

Janice 4Horseshoe Bay is the dive destination within the heart of Komodo.  It harbors a spectacular series of dives within a small area, and at the same time offers the first opportunity to view the infamous Komodo dragon in one of its natural habitats, the beach on Rinca Island.  Here, crab eating macaques skip around on the rocky section of the beach collecting the shellfish when the tide is out, while the dragons slink out in public only when the sun is at its peak and the sand at its warmest.  The dragons are surprisingly inactive and look more like statues sculpted from the very sand upon which they rest.  They only appear to be alive because of their nonstop drool that seems thick enough to tether them to the beach.  Fortunately, they do not like to swim so much.

Janice 8The dives in this area often had a bit of current at the surface, so negative entries were necessary.  However, once under the surface, the current was not detectable.  Cannibal Rock, named after a behavior of the dragons and not the humans, is a fabulous volcanic peak that you circle but never in a single dive, as it is crowded with soft corals, anemones, mating nudibranchs, frogfish, and shrimp.  It is possibly the worse case of ADHD my eyes and I could ever have, because I could not prioritize where to stop and to look.  Thankfully, I had the Incredibles, a.k.a. the dive guides from North Sulawesi, to help me sort it out and to identify specific, unique creatures.  The Yellow Wall o’ Texas is one of the most extraordinary wall dives on the trip, in that the soft corals are swollen open all day long due to currents even in the bright sunlight.  It is a hypnotic ride along a wall of soft corals and anemones rhythmically responding to the current, but macro creatures can be found if there is a break in the flow.  I spotted an enormous tambja affinis nudibranch (not exactly macro) and two zebra crabs on a fire urchin glued to the wall.

KomodoEventually a dive comes along where I had to pay for all of the delicious desserts eaten on a 12-day liveaboard.  The Three Sisters was finally that dive. The Three Sisters is a dive site of three underwater pinnacles that become progressively higher and are separated by several meters.  The current was flowing into one side of the pinnacles so that the burn came at the entry just downstream of the current and in between them where the current ran through.  On the entry, I refused to let my male dive guide get away from me so I kicked and kicked until I reached the other side of the ridge, stopped to breathe for a few minutes, and then proceeded.

Janice 10We were searching for the so-called chocolate crunchy peanut sea star (scientific name unknown), a species of starfish reportedly identified by the Seven Seas at this site, but instead found a giant yellow frogfish on the third sister and three orangutan crabs crowded on a single bubble coral on the sea floor.  The highlight was a sort of underwater interracial couple, a trumpetfish closely lingering over a pufferfish.  This behavior trick of the trumpetfish was not new to me.  The trumpetfish hovers over the pufferfish just out of sight and is able to snatch unsuspecting fish that are normally at ease in the presence of the pufferfish.  The pair really appeared to be more attentive to each other, like a romantic couple, rather than a devious trumpetfish camouflaged by a puffer.  Rita, one of the other guests, even predicted the possible variations of their offspring if their real purpose was to mate.  A spiny trumpetfish?  A long snouted, yellow puffer?

Janice 13There were “sand-based” breaks from the boat.  A very serious beach volleyball match took place between the crew, guests, and locals from an island that I can only report is somewhere.  It was an unpredicted event in life.  An easy hike to Pink Beach on another island to watch the sunset emphasized the remarkable diversity of the landscape of Komodo.  The pink sand on this beach is created by the fragmentation of red coral.

Beauty is flaunting itself everywhere in Komodo, but it lies deep within the muck dives if you are open to the challenge of finding it.  I have noticed all too often divers surfacing before their 60 minutes are up in exasperation because muck dive sites are not “pretty”.  To me, there is something compelling about these dives even though they at first may appear to be desolate.  The dive guides always find something, so I take on these dives as a personal challenge to hunt as they do and persevere until the end of the 60 minutes as if I might find something awesome too!  An easy afternoon muck dive at Wainilu proved exactly this point.  For about the first 30 minutes of this dive, I felt as if I was immersed in a black and white photo, as there was low visibility and little sunlight.  And then finally, a radiant spot of color, a yellow-ridged ceratosoma, appeared on the coral rubble.  More nudibranchs came after that, including a huge, lumbering solar powered phyllodesmium longicirrum.  Finally, our dive guide, digging through the coral rubble, uncovered a spiny tiger shrimp, one that I could actually see without a magnifying glass.

Janice 12That feeling that a dinosaur would appear at any moment followed me throughout the trip, but it was especially on the night dives that I felt totally immersed in the primordial soup that is Komodo.  Coral Garden is a name that sounds innocuous enough, but it was here that tiny bioluminescent beings hurled themselves at us at night.  No one had a name for these creatures pulsating orange light, but I was clearly not the only one seeing them.  At Torpedo Point in Horseshow Bay, I finally made a find that even the dive guide envied.  Just as I reached the bottom, my flashlight beam caught a juvenile ornate ghost pipefish bouncing vertically over the sand as if its nose were too heavy.  Our Incredible for the night dive quickly evened the score by finding the parent to the juvenile and then essentially outscored us by making torpedo rays appear out of the sand, revealing hidden shrimp in basket sea stars, and coercing delicate crabs out of their soft coral hideouts.  Evolution seems to have a complete lack of any rational purpose when you evaluate the diversity of the creatures on these night dives.

KomodoAnd at the end of a night dive, you surface under an unadulterated spectacle of the stars.  In a place like Komodo, where there is no interference from man-made light, I could use even a weak flashlight, point to a star, and feel as if the beam of light reaches all the way into outer space and actually touches it.  It occurred to me then that the magical life of Komodo might be created by some sort of a chemical reaction requiring the components of seawater and volcanoes and is ignited by sun-, star-, and moonlight.

KomodoWe were once again anchored in the harbor of Labuan Bajo, and Komodo and Rinca, Sangeang and Sumbawa were all new “is this even on Google maps” destinations that I had traveled to.  Only the domestic flight remained.  We had news that there had been an incident two days before where a cow wandered inadvertently in front of a jet that had just landed at the airport (the unpredictable).  While no one was hurt, the plane was damaged, and this meant a delay as the airlines was catching up for the lack of flights on the two previous days.  Considering these circumstances, I was, of course, anxious about the flight, but as we finally safely left the ground, I was more anxious about leaving Komodo and not ever returning.

Tips for… Navigation



Not the most fun of topics we guess, but pretty important for any diver! Now we are sure that there are some of you out there that steer away from the navigation side and are quite happy to follow along at the back. But if you are one of those divers and the reason is because you think that it is ridiculously hard.. we want to give you a few basic tips to help you!

Now using a compass may look scary but actually there is not much to it. First rule to remember… North is North under the water as well as on land… it doesn’t change! So, with that in mind we can use that pretty easily under the water to at least give us a point of reference whilst we are diving, even if you are not leading it. Knowing the direction that you are going and how deep you are is a good reference and will help you to become more confident. Get into the habit of taking a ‘bearing’ – fancy word for direction – on the surface before going under and check the bearing as you are diving.

Knowing which way is left and right – well, when going right, the numbers increase, and when going left, the numbers decrease… easy! Starting off with turning left and right 90 degrees will start to get you into the habit of making turns. Try not to use complicated numbers when you first start off, nobody likes maths at the best of times, let alone trying to add 273 to 32 under the water! Keep it basic.

Last but not least, navigating is not all about using a compass. If you are not a fan of it and want to keep your dives simple, there is nothing wrong with natural navigation. There are some amazing sites around our coastline that are perfect for this – harbour walls, piers, open sea coves, all allow the point of reference to be followed on one side of your body on the way out and the opposite on the way back. You can also check that you are going the right way on your return as the depth will start to decrease. This is a great way to start building your confidence with navigating if you are new to it, and what is even better, lots of marine life love to congress around these rocky areas!

Other aspects to consider to throw into your natural navigation bag are picking some land marks during your dives. If there is something notable that doesn’t move (fish are not highly recommended!) take a note of this and use it as a reference and pick another. On the return journey, you can use these ‘markers’ to find your way back to the starting point. A nice and simple way to find where you are going.

So, give it a go in a nice shallow bay area and see how you get on… practice makes perfect!
