Wrapping Up a Week of Diving

We ended up a week of diving, bush trips and industrial-strength socializing with Anita, Wouter and Anita’s father, Jos, today. It’s been a pleasure having them with us. Yesterday I realized that I had no photos of Jos. So, I took this shot of him steering Faded Glory:

Jos turned out to be very handy with a boat. On our last day, he handled the boat while the rest of us did a drift dive at Magic Passage. Communications were a little light, as we do not speak each others’ languages, but he is a very pleasant fellow. I wish that we could have had some heart-to-heart conversations.

Here is a shot of Anita and Swami Monty in the water at Magic Passage with Faded Glory,  Jos at the wheel, coming up in the distance:Anita, Jos and Wouter are leaving tomorrow morning. Wouter is an avid diver and runs with a crowd of dedicated techno-human-dolphins in the North Sea. I wouldn’t be surprised if we begin to get applications for diving here in Madang. It’s an entirely different experience from their normal dives. I think that Wouter found it a pleasant break from the adrenaline-drenched sport as it is enjoyed off the coast of Belgium.

Among the critters that we saw on our last two dives at Magic Passage  and Rasch Passage  was this Starfish (Nardoa rosea)  practicing Extreme Yoga:I am able to contort my body like this, having practiced yoga since I was a pre-teen. Okay, okay, I’m not as nimble and Gumby-like as I once was. However, I’ve not yet reached the point, at sixty-six, at which I need to ask myself, “Can I still do that?” This is a great blessing for me, as the physical activities (yeah, all  of them) are important keys to my well-being. I owe much of this to my Dad, an accomplished athlete, acrobat and dancer who taught me the principles of physical fitness as a life-goal and the concept of the body-aware spirit.

We may as well have a look at another starfish. This one, I think, is a Fromia nodosa  with its little toes curled up very cutely: You can’t swing a dead cat here without smashing a starfish. We have many different species and I have neglected them severely. I’m certain that their tiny little feelings are hurt. I’ll fix that in the future.

I got a bit of a “wow” experience from this huge mob of Reticulated Dascyllus (Dascyllus reticulatus):We would normally see a dozen or two in a plate coral. This was a huge plate and was home to a couple of hundreds of these lovely little purple-lipped fish. I love to play “scare the fish” with the Dascyllus.  If you slowly stretch your arm out over the plate with your hand closed in a fist and then quickly open your hand the entire gaggle will dive simultaneously into the coral and disappear. It’s like magic. Now they’re here – now they’re not. If you look closely, you can see them trembling in their little nooks and crannies where they hide from predators.

Barrel Sponges fascinate me. Some of them are huge. This Xestospongia testudinaria  is about two metres from bottom to top. Some are much larger:

You can see a few Purple Anthea (Psudanthias tuka)  swimming in front of the sponge. The “purple” in the common name is a relative term. As with many fish, the colour that you see underwater is radically dependent on the depth, the colour of the sky and the condition and tint of the water. Sometimes P. tuka  appears purple and sometimes blue. The yellow dorsal fin edging and caudal fin are constant. The fish appear a bit motion blurred, because I was forced to a slow shutter speed by the low light level.

I am exceedingly happy, nay, overjoyed by this image:As you may gather, I’m easily aroused from my usual “so what” attitude. When I saw this fish, I became terribly excited. That will give you an idea of what a fish geek that I am. The reason for my shaking hands and fumbling fingers is that I have never seen this fish before; it was my first sighting. It is a species of Shrimpgoby (Ctenogobiops tangaroi).  There are several fortuitous aspects of this shot, aside from the novelty factor. First, there is the brevity of the sighting. I barely had time to raise my camera, hold my breath for a few seconds and fire off a shot before it disappeared down its hidey-hole.

Another lucky aspect of this image is that I caught the fish’s partner, a commensal shrimp (Alpheus ochrostriatus)  bulldozing a load of sand out of the shared shelter.

I’m not looking a gift fish in the mouth.

I Bet That You Have Never Eaten One of These

Not much is happening here in Madang. That’s just as well, since the mood here this year is distinctly sour. Town is crowded with people moving from place to place and the tension in the air is electric. There is a liquor ban in place until at least after New Year, some say until March. It won’t do a lot of good, since there is plenty of bootleg beer and weed available. Like the Chinese say, the next month or so will be “interesting times”.

Anyway, to prepare your palate for the holidays, I’ll show you some items that I am nearly certain will not be showing up on your menu.

This is a familiar character on Madang – Ples Bilong Mi,  Mr. Lizardfish. Its given name is Reef – that’s Reef Lizardfish. Does that sound like a good name for a Hollywood actor? It’s a stage name, anyway. Who would buy tickets to see someone named Synodus variegatus  in a movie?Reef Lizardfish (Synodus variegatus)

Never mind. I took an extra silly pill this morning.

This adorable little thing has the equally adorable common name of the Papuan Toby (Canthigaster papua):Papuan Toby (Canthigaster papua)It’s a flash-lit shot that I got at the B-25 bomber The Green Dragon.  The colours are slightly oversaturated by the flash, but it’s so pretty that I’m not going to complain. Sometimes I prefer to forget my fussiness about getting things accurate and go for the gorgeous. This little sweetie persuaded me to let it shine.

Here is a tasty little Nudibranch. It’s a shame that they don’t make candy that looks this pretty. It’s a Phyllidia coelestis:Nudibranch (Phyllidia coelestis)

Nudibranchs are becoming strangely scarce around Madang. I am very suspicious about the pollution level in Astrolabe Bay.  First the sharks disappear and now the Nudibranchs. What’s going on?

This little beauty is a Latticed Sandperch (Parapercis clathrata):Latticed Sandperch (Parapercis clathrata)

I shot it on the top of the reef at Magic Passage  last Saturday. The light was very good. In this shot I deliberately oversaturaded the colours of the fish. It’s a trick that I use to remind myself of the colours that I saw. Fortunately I have an excellent visual memory. Unfortunately, I can barely remember my name, or anybody else’s. I can remember a face for a decade. Five minutes after coming aboard Faded Glory  and introducing themselves, I have to ask new divers to remind me of their names.

I had the brilliant idea of showing you a different coloured Christmas Tree Worm (Spirobranchus giganteus)  every day until Christmas:Christmas Tree Worm (Spirobranchus giganteus)

I don’t know how that is going to play out. I’m running out good images in my accumulation. I’ll have to get a lot of shots on Saturday.

Finally, the least likely to show up on your plate are these miniscule, but undoubtedly yummy shrimp:Shrimp in fungiform (Heliofungia actiniformis) coral (species unknown, possibly Periclimenes holthuisi)
These are tiny, nearly transparent commensal shrimp that live in a fungiform coral (Heliofungia actiniformis).  The species here is the problem – identifying it. It could be Periclimenes holthuisi  or possibly P. venustus,  though there are specific markings on each of those species that are missing or distorted in these specimens.

The interesting thing here is that it is possible  that you are looking at an undescribed species. It happens all the time here. Every year species formerly undescribed are discovered near Madang. This could  be one.

Anybody out there want to check this one out?

Heart of the Hunter – Part 2

Yesterday, I dumped a bunch of images on your screen that I’m preparing for an article for Niugini Blue  magazine. The title will be Heart of the Hunter. Look back at my post from yesterday to read all of my blather about that.

Today, we’ll just look at some of the rest of the images that I’m submitting.

You’ve seen the Spotted Shrimpgoby (Amblyeleotris guttata)  here before. I’ve even managed to get shots showing the commensal shrimp that lives in the same burrow. I spent about fifteen minutes sneaking up on this scene to get the fish along with two  of the  shrimps Alpheus ochrostriatus:

Spotted Shrimpgoby (Amblyeleotris guttata) with shrimps Alpheus ochrostriatusThe timing here is very tricky. I could see that there were two shrimps living with the fish in the burrow, but it took a lot of patience to wait until both of them came out at once, pushing sand in front of them as if they were tiny bulldozers. The Spotted Shrimpgoby appeared previously here and here. If you get too close or make a sudden move, they all pop back in the hole in a flash.

Stalking relatively immobile critters is easier.  You’ve seen this nudibranch (Notodoris minor)  here before several times (put notodoris in the search box):

Nudibranch (Notodoris minor)In this shot, I think I’ve finally figured out how to get the subtle bumps and curves of the body of the beastie to show clearly. The thing is so bright and so monochromatic that you can’t really see this much detail with the naked eye. It’s an interesting example of how a photographic image can show you details that you can’t see with your eyes. Underwater, this critter looks pretty much like a blob of bright yellow with black stripes. It’s very hard to make out any detail.

I shot this image of the Spotted Porcelain Crab (Neopetrolisthes maculata)  a couple of years ago with my previous UW camera, an Olympus C8080:

Spotted Porcelain Crab (Neopetrolisthes maculata)Though there a lot of variables that I can’t account for, it’s still interesting to compare the Olympus shot with this one of the same species shot last week with my current outfit, a Canon G10:

Spotted Porcelain Crab (Neopetrolisthes maculata)As I said, there are too many variables to make a direct comparison, but it certainly looks as if I’ve lost nothing in the change.

This shot of a Spotted Garden Eel (Heteroconger hassi)  is one that I must admit makes me feel almost like a pro:

Spotted Garden Eel (Heteroconger hassi)

It’s not so much that it’s technically perfect – it isn’t. However, if you understand the behaviour of these eels, you will appreciate how difficult it is to get a good, clear close-up. The garden eel is usually found in mobs sticking up out of the sand. That’s all well and good – and quite pretty. However, when you approach them, they all pull back down into their holes; it’s their best defense. To get this close to one requires Job-like patience and a full tank of air. I cheated a little by easing a bit of telephoto into my lens, something which is normally useless underwater, since there is always too much stuff floating around.  I also had to do an enlargement trick (the multiple 110% enlargement method, in case you’re a Photoshop fan) to get the image big enough to crop out the middle and still have good detail. I’d guess that the front of my camera was about a half-metre from the eel.

Look, he’s winking at me.
