My journey began on the 42m Kararu, a traditional rigged sailing vessel which serves as an extremely spacious liveaboard. It operates from Bali, 160 miles to the west, but the journey to and from Komodo is punctuated by dive sites which are fascinating in their own right, and serve as a build-up to the world-class diving at Komodo and its neighbouring island, Rinca. My host was the boat's co-owner, Tony Rhodes, a Brit with an easy manner and a knack for spotting near-microscopic animals.
On an early dive at a site called Mentjang Wall, we were finning along in mid-water when Tony suddenly swooped down to the reef. I followed, squinting at the scrappy patch of coral to which he was pointing. At first nothing, then I could make out a tiny brownish nudibranch (of the Flabellinidae family). He had seen it from 10m away! Suspicious, I wondered if he had sneakily placed it there
when I wasn't looking, possibly inspired by Donald Pleasence's similar trick in The Great Escape.
As I was to discover, his spotting skills were quite genuine. While there are plenty of sizeable creatures to marvel at in Indonesia, the area does tend to attract divers with a penchant for the diminutive. These are rich seas, and there is a perpetual battle for space on the reefs. After just a few days, your eyes become familiar with the environment, so that semi-camouflaged critters begin to reveal themselves. Professional dive guides become finely attuned to this sort of diving.
Komodo National Park comprises the seas around the islands of Komodo, Rinca and Padar, and some smaller islands. It's a two-wetsuit trip: on the northern side of the islands, the water is warm, and most people dive comfortably with the thinnest of skins. Cool, nutrient-rich upwellings prevail on the southern side, where 5mm suits, hoods and gloves are the order of the day.
These islands act like a dam, holding back the warmer Pacific waters, which are then forced through various straits, creating a pressure void along the park's southern side. This allows cold water from the Sumba Sea to rise up, effectively replacing the water removed by the currents at the surface. With the cold water comes a bloom in phytoplankton, forming the basis of Komodo's super-charged food chain. It is a very, very special place indeed.
The results of these crazy upwellings are best experienced at Horseshoe Bay on Rinca's southern side. These are the most crowded reefs I have ever seen, but the payoff is low visibility caused by all those nutrients suspended in the water. Horseshoe Bay's famous site is a pinnacle known as Cannibal Rock (named after a monstrous Komodo dragon seen eating one of its own kind nearby), where dense swathes of black, yellow and red crinoids jostle for space.
It's a great place to test buoyancy skills, because crinoids stick to neoprene like glue; any contact whatsoever and you've got yourself a hitchhiker. Once, after taking head-on photographs of an implacable lizardfish, I looked down to find I had picked up two featherstars complete with clingfish and crinoid shrimps - a whole ecosystem! I guiltily set them back on the reef.
Just outside Horseshoe Bay is a fascinating site known as the Great Yellow Wall of Texas, renowned for its soft corals. Visibility here was reminiscent of British shore-diving standards, and the coral polyps were all retracted, so I hardly saw the reef in all its glory. Still, I could appreciate the sheer intensity of the place. Nestling among the crinoid forest were some fascinating animals, including brightly coloured sea apples, a spectacular member of the sea slug family. Tiny hawkfish nestled between the fronds of soft corals, while gobies darted around their tiny territories.
Night dives were even more atmospheric. The currents sweeping over Cannibal Rock were too much to cope with after dark, so we searched for night creatures in the shallows. At first glance, the sandy expanses were devoid of life, but a closer inspection revealed a wealth of nocturnal drama. Octopus each the size of a child's fist moved over the sand, extending their tentacles into tiny holes as they hunted for suitably small prey. Every now and then, they would retract their foraging limbs in pain, having received a nip from some hidden sand-dweller.
Inshore sites often serve as nurseries. I saw lots of tiny fish, including juvenile oriental sweetlips (flapping wildly like some out-of-control bumblebee) and a rockmover wrasse complete with protruding unicorn's horn. Photographers found the night dives to be the most productive of all, and some would sacrifice an afternoon dive to be alert for the evening.
The best night dive took place beyond Horseshoe Bay on a sandy slope near Banta Island. The site has a particularly cheesy name - 'It's a Small World' - which nevertheless hints at the macro wonders which have made it their home. I dropped in and descended 10m to what looked to be a lunar landscape, devoid of life. The gritty sand billowed briefly into the water column as I landed on the sea bed and looked down to see a skeletal face leering back with utter contempt.
It was a stargazer, a voracious lunge-predator whose stealth is rivalled only by its monumental ugliness. It buries itself in sand right up to its eyes, then waits for a suitable morsel to happen along. Ambush predators don't like being seen, and this one looked up at me with undisguised disgust as I gently fanned the sand away from its fearsome features. Eventually, the indignity of being exposed in this way proved too much; it launched itself off the sand and sped off into the darkness.
