Thailand: scuba diving in the Andaman Sea—Part 1

25 November Krabi
Now I return to Thailand for scuba diving in the Andaman Sea! This will be on a liveaboard out of Khao Lak with Similan Diving Safaris www.similan-diving-safaris.com/index.html. It would have been a long overland journey from Kuala Lumpur, so I looked into flying and found that although Phuket would be the closest airport, I could get a cheaper fare to Krabi. So I chose the Krabi option and booked Air Asia AK 860. The flight didn’t depart until 5:05 p.m., so after checking out of my Airbnb, I swung by the MTR restaurant in Brickfields for an excellent South Indian thali, nearly the same as I had enjoyed there last night. Then I got a bus to the airport, but I forgot to specify the terminal and was given a ticket to KLIA—the main terminal—where I had to take a short train ride to KLIA2 for the huge complex used by Air Asia. I had paid a little extra for a window seat in the front and enjoyed views of the rivers and coastline of Malaysia as the flight swung out over the Andaman Sea. 


We are taking off from KLIA2, the vast port of Air Asia and other budget airlines.
In the distance you can see KLIA used by other airlines and with its own control tower.

The plane climbed into clouds, then descended through hazy sunshine over southern Thailand’s extensive oil palm and rubber plantations. After 1:20 in the air, I landed at Krabi’s small airport, well equipped with an international terminal. Immigration went far faster than in Bangkok, and I got a shuttle bus toward town, but rather than drop me off near my accommodations on the way, the bus went all the way downtown, where a van took me to my Airbnb at White House, close to the bus station and main highway. The room was very spacious and clean—better than I’m accustomed too!
 
26 November Khao Lak
I easily got a minibus in the morning for the nearly three-hour ride inland and along the coast to Khao Lak, where I would be boarding the liveaboard boat tomorrow. The ride went through pretty scenery with sheer limestone pinnacles and, near the end, views of the coast. I got a 400-baht room at Happy House next door to the dive shop, then met up with dive staff and some of the divers for the five-day liveaboard excursion. Lastly, I had a fine Penang curry at Spinach Restaurant, enjoying the flavors and presentation.
 
27 November Andaman Sea
When I had signed up a few weeks ago for this trip, I was the only person, but more people had joined since and we delayed our departure a bit for a few more to arrive today. A short minivan ride took us to south the port and our home for the next five days, the Similan Explorer. We would be 15 divers, 4 dive leaders, and 5-person Thai boat crew. We had a profession underwater photographer onboard, Krzysztof Bargiel, who would swim among each of the groups to snap well-composed portraits of us plus the abundant sea life. He also took short videos and offered a package of everything, which I purchased and transferred to my computer. You can also see his beautiful photography at www.facebook.com/krisbargie

Shortly after sunset we motored off and one of the Thai crew paid respects by offering incense to a shrine at the bow of the boat. Next, a crewman lit a string of firecrackers wrapped around a stick to chase off any bad spirits before we headed into the open sea.

28 November Andaman Sea
Our little boat did a lot of rolling last night, and despite taking a motion-sickness-prevention tablet, I felt a bit out-of-sorts on the first dive, at Hideaway on the south side of Similan Island #5. Yet last night’s dinner stayed down and I felt good to be back in the sea. The 57-minute dive swung by the tuna wreck, lying on its side, and weaved among the hard and soft corals. We saw a great many fish, most with bright colors or prominent patterns. I don’t know why the sea creatures have such features, but there must be good reasons! Each fish has its niche—resting on the bottom, hiding in cracks, hanging out near the corals, living in poisonous anemones, swirling over the corals in dense clouds, or hunting in the open water. We saw a cuttlefish, an intriguing creature with slits for eye pupils and an undulating membrane skirt for moving through the water. A sea snake with distinct white-and-black banding slithered through narrow crevices in search of a snack; although the snake’s venom is very toxic, divers are not on the menu. Triggerfish are the only fish that commonly attack divers, but they do this only when nesting, and the ones we saw this morning were peacefully foraging for food.
 
The second dive went down at West of Eden, a dive site near Similan Island #7. Again, lots of corals and fish among the giant granite boulders, though some areas of sea floor had mostly dead coral. Sometimes we could see splendid garden eels poking their heads above their tunnels in the sand and facing the current; they are very shy and retreat if anything approaches. Giant eels—at the other end of the size spectrum—display sharp-looking teeth though ignore us divers. I caught a glimpse of a peacock mantis shrimp, a relatively large species with a colorful body and exceptionally good vision in their stalk-mounted eyes.
 
The afternoon dive meandered through even bigger granite boulders and picturesque swim-throughs at Elephant Head, off the southern tip of Similan Island #8. Giant barracuda, with their long sleek silvery bodies prowled above while tiny pipefish (related to seahorses) clung to corals near the bottom. We got to see Kuhl’s stingrays and the diminutive and very pretty ribbon eel, which we knew as a male because of its black coloration.
 
When the sun went down, we did too! Our night dive began at 7 p.m. at Ao Nam Chai between Similan Islands #8 and #9. Some fish go to sleep, and the parrotfish even wraps itself in a mucus cocoon, said to prevent nocturnal predators from sniffing it out. Crabs, including a decorated spider crab, and shrimp come out to forage. We saw lots of filter feeders such as feather stars. Flatworms are pretty to watch as they undulate through the water; their body is so thin that they can ‘breathe’ through their skin and don’t need gills. A moray eel and bobtail squid made appearances as well. Although both lionfish and scorpionfish have extremely toxic spines, the scorpionfish uses camouflage and stealth to catch prey while the ungainly lionfish have dramatic white and red strips and showy ‘plumage’-like fins yet still manage to catch their meals.


Donald Duck Bay on Similan Island #8 is a popular shore excursion for divers.


The banded sea krait
(Laticauda colubrina) is very agile in the water!
They return to land to digest their prey, rest, and to reproduce.


You can see the paddle-shaped tail, which enables the sea krait to travel five times
faster in water than on land. They primarily feed on varieties of eels, but also eat small fish.

Titan triggerfish
(Balistoides viridescens) have strong teeth!
There are about 40 species of triggerfish in the family Balistidaehas.


Barrel sponges may have a lifespan exceeding 2000 years!


The giant moray 
(Gymnothorax javanicus) is the largest moray eel and
can reach up to 3 meters (9.8 ft) in length and 30 kg. (66 lb) in weight.


Soft corals come in beautiful hues.

Schooling bannerfish 
(Heniochus diphreutes), also known as false moorish idols, are a butterflyfish.


This may be a day octopus
(Octopus cyanea), a master of camouflage that can change not only the color and patterns
on its skin, but also its texture. A researcher observed one change its appearance a thousand times in seven hours!


These may be yellowfin surgeonfish (Acanthurus xanthopterus), part of a family of about 86 species of
surgeonfishes, tangs, and unicornfish. All have one or more scalpel-like spines on each side at the base of the tail.


Blackspotted puffer 
(Arothron nigropunctatus)
Almost all pufferfish contain tetrodotoxin that makes them foul tasting and often lethal to other fish.
It’s said that one pufferfish has enough toxin to kill 30 adult humans, and there’s no known antidote.

29 November Andaman Sea
Our daily routine continued: an early morning dive at 7 a.m., breakfast, rest, late-morning dive at 11 a.m., lunch, rest, early afternoon dive at 2 p.m., snack, rest, sunset (5 p.m.) or night (7 p.m.) dive, dinner, rest, and repeat the next day! Although diving is relaxing, it’s still tiring and can be strenuous at times when going against a strong current. We try to take advantage of currents by hopping in the water at one end of a dive site, then drifting through it and getting picked up by the boat at the other side of the site. I and most of the divers used a mixed gas called ‘Nitrox’ that has about a 30% oxygen content to reduce nitrogen absorption; this lets us stay down longer and is said to reduce tiredness. I recently purchased a diving computer that continuously makes calculations about nitrogen absorption at the varying depths and times. But it is not failsafe, as I later found out.
 
We first dove at Three Trees, named for a trio of prominent trees on Similan Island #9. On this drift dive with the current we saw a bunch of Kuhl’s rays, pufferfish, the ‘perfectly painted’ powderblue surgeonfish, the large Napoleon wrasse, parrotfish, oriental sweetlips, and a hawksbill turtle. We got down to 27.5 meters, averaged a depth of 17 meters, and stayed in the water just under an hour.
 
Our dive at North Point off Similan Island #9 also went deep, to 30 meters, as far as we go in sport diving. I liked swimming among the giant boulders and their canyons, but the shallows had a lot of depressing-looking dead coral rubble. We saw a porcupine ray and a lot of big fish including grouper, yellowfin and longnosed emperorfish, and Napoleon wrasse.
 
Koh Bon, an island between the Similans and Surins, is unique for being composed of limestone while all the others are granite. That affects the underwater world with spectacular cliffs off the west ridge. A strong current gave us a workout on the north side of the ridge. Lots of staghorn and other hard corals grow in the depths. Tiny cleaner wrasses like to pick off parasites and dead skin from big fish, but can be overeager and annoy both fish and divers—one kept nipping at my ears! A pair of small fish engaged in head-butting just like goats, then they somehow interlocked their dorsal fins and spun around for several seconds, something goats cannot do!

Just like people, fish enjoy having a good dinner, and become especially active in seeking food around sunset. So we jumped in about 5 p.m., again at Koh Bon, and watched the lively fishy scene.
