Night dive

A pretty nice and relaxing dive off the back of the boat straight into the reef. I was hoping to see a giant moray swimming out hunting but no such luck for me, although everyone else bloody saw one!

Saw quite a few parrotfish sleeping in their holes, lots of feather stars that closed up with the light shining on them, hundreds of cleaner shrimp, a spiny lobster’s antennae poking out of a hole, a red crab that was about 15cm wide, and bannerfish.

Still had 150 bar left at the end of the dive – shame the planned dive time was so short!

What a stunning dive! We descended onto Batfish Rock and swam amongst the big granite boulders where there were soft corals and sea fans sprinkled around. There were schools of little fish everywhere, giant trevally and bluefin trevally cruising past and hunting the little fish, a school of batfish hovering near the bottom and as we cruised past one of them followed us around for about 10 minutes. We swam off the main rock and out into the blue where there was a massive school of barracuda hovering in midwater and occasionally swirling around us and in front of us with a few giant trevally swimming with the school as well. The batfish was still following me at this point, and would come up and swim very close to my face and when I reached out to touch it, it almost looked like it would let me stroke it before it turned away at the last moment.

Also saw amongst the big boulders some large black sweetlips, oriental sweetlips, a brown grouper that was about a metre long, a banded sea snake, a giant triggerfish moving bits of coral between its jaws to get at some food, a flutemouth, quite a few anemones with anemonefish, filefish, and lots of various colourful reef fish.

We ascended up the mooring line where we hung on for dear life during the safety stop as it seemed like the current was roaring, even though it wasn’t so bad on the bottom. But as soon as we let go of the line to drift back to the boat the current seemed OK.

Sophie and I were all smiles back on the boat!

Dive 274: The Ridge, Koh Bon (Thailand)

Dive time: 00:41:00
Max depth: 28.0 metres
Temperature: 29 C
Visibility: 15 metres
Buddy: Sophie
Surface interval: 03:09:00

Our second dive of the day and we dropped down in a similar spot to the first, descending down near the ridge and then having a relaxed pootle around.

As soon as I came around the tip of the ridge, I could hear frantic tank banging so I followed everyone’s gaze to see a MANTA RAY!! It was a bit of a way in the distance, further away than yesterday and with poorer visibility but it seemed to just be hovering in midwater above our heads. The current was absolutely ripping past the point and I actually had to hold onto the rocks to stay in the same spot if I wasn’t going to get swept out past the point. Wish I had been a little closer to it!

After this we hovered over the ridge and the reef for a while, checking out the cleaner wrasse, napoleon wrasse, bluefin trevally, angelfish, a couple of smashing mantis shrimp scurrying along the gravel, juvenile anemone fish, fusiliers, and a purple ribbon of nudibranch eggs swaying on the reef.

About half an hour into the dive everyone swims off into the blue, presumably to look for the manta again. Our dive guide James signals that we make a safety stop, at which point I’m mightily annoyed since I still have 100 bar and we were only 35 mins into a 50 min dive plan. I even signalled to him that I still had 100 bar and he just told me to ascend a little. Was pretty incensed during the safety stop (made for interesting buoyancy control) and came back to the boat with 80 bar and still 9 mins of dive time remaining.

Dive 273: The Ridge, Koh Bon (Thailand)

Dive time: 00:54:00
Max depth: 27.1 metres
Temperature: 27 C
Visibility: 15 metres

Surface interval: 18:57:00

A new dive group, a new dive leader and a new buddy. We dived the same site as yesterday but the visibility had dropped a fair bit since. Not sure if it was the rain or the current.

We dropped down on the ridge, and the current was a fair bit stronger than yesterday. We saw a spiny lobster hiding in a hole, before we swam out deeper into the blue to look for mantas. We stayed out hovering just above the reef for a little while, but there was no manta sighting. Quite a few giant trevally cruising past though.

Back on the reef we swam over big patches of dead coral. I saw quite a few bluefin trevally, juvenile fusiliers, a giant moray hiding in a hole with a banded boxer shrimp crawling over cleaning it, an anemone with lots of juvenile anemonefish and a little porcelain crab as well, a giant triggerfish, bannerfish, and moorish idols.

Towards the end of the dive, Sophie was low on air so she ascended with the dive guide James while I tacked onto another group for a few minutes more pottering around and the safety stop.

Dive 272: The Ridge, Koh Bon (Thailand)

Dive time: 01:00:00
Max depth: 27.1 metres
Temperature: 29 C
Visibility: 40 metres

MANTA!!!! After Axl going through the dive brief without mentioning the M word in case he jinxed us, we descended onto the ridge and within 1 minute of hitting the bottom at around 20m, On banged furiously on her tank and signalled a ray. We followed her pointing and sure enough there was a manta ray swimming at our depth coming within 10 metres of us. It was accompanied by a couple of pilot jacks. It was so beautiful, with black and white markings on its body. It swam past us, did a u-turn then swam past us again before disappearing into the blue. We all cheered!!

We continued swimming along the ridge, saw a banded snake snake and a big giant moray close to the sandy bottom, along with a peacock mantis shrimp scurrying along the sand. I heard someone squeal behind me and saw an eagle ray swimming by. Score! Already an amazing dive and we were only 10 minutes in.

We came up to the top of the reef and pottered around a bit where we saw a couple of Napoleon wrasse, a big blue one and a smaller more coloured one. Also saw another giant moray, loads of moorish idols, a hermit crab, juvenile trevallies schooling juvenile fusiliers into balls and then attacking (a bit like our own nature documentary happening in front of us), a few lionfish, a porcelain crab hiding in some fire coral, anemonefish, some large groupers, butterflyfish and angelfish, some black snapper, and some barracuda at the surface. Amazing dive!
