A Once In a Lifetime Shot

The weekend got off to a perfect start this morning when I crossed the terminal wires on my boat battery and blew the voltage regulator on my engine. I had to cancel the day for five divers standing on the dock waiting for me. I hope the remainder of their weekend went better than mine. Fortunately, Richard Jones is in town, so I went out on his boat, Sanguma  along with Jenn, Jo and Ush.

I have lots of other news about the weekend, some good, some not so. I’m sitting at the office on Sunday afternoon writing this because the power to the security camera pole where my wireless connection makes its hop to my house has been out all weekend and, of course, my wonderful TELIKOM phone lines won’t carry data today because there were a few drops of rain last night.

I could keep on complaining for hours, but I don’t have the time. Too bad. It’s my favourite hobby.

One of the bright spots of the weekend is in this image:If you’re not a diver, you might not think that it’s such a big deal. Believe me, it is.  The shot above was taken by available light at about eighteen metres at The Eel Garden  at Pig Island.

What you’re looking at is two giant Notodoris minor  nudibranchs engaged in a super slow motion mating act. (UPDATE: Frank Peeters points out that this is actually one N. Minor.  His explanation is perfect; I can’t argue with it. See our comments below. I’m only slightly deflated.) The reason I’m showing you three nearly identical images of the same scene are partly technical and partly because I’m so dumbfounded by my luck that I can’t stop inserting the images in this post. It’s one thing to see a Notodoris minor.  I’ve found a spot at The Eel Garden  where I can usually find one if I take the time to look. It’s another thing to find two of them together. However, I have never before, and very likely never will again catch two of them in the act of laying and fertilising eggs. The shot above was lit by the flash on my camera.

Needless to say, I grabbed many, many exposures of the pair. I did not want to risk something going wrong. I tried several different camera settings. I made up this image in Photoshop which, though it seems faded compared to the others, shows the fine structures in high detail and really gives a more accurate idea of the shape of the things:The image above is over twice the pixel dimensions that I usually put in the journal. I normally limit resolution to 1600 pixels. This makes them load faster if you want to click to enlarge. It also protects me a little from those who steal images from the web and foist them off as their own. Yes, it has happened to me. My copyright (see the bottom of the page) allows free non-commercial use of any of my images without seeking permission as long as you simply attach my name to the image or (preferably) include a link to Madang – Ples Bilong Mi.  That’s fairly small payment for the work that I put into presenting my best work on this site. I’ve found plenty of my images on other web sites with no attribution. I’m not sure why someone would do that, but it doesn’t make me particularly happy. Anyway, if you want to see some amazing details of the egg-laying nudis, click on the image above and be ready to download about a half of a megabyte.

I also thought that you might be interested to see the old wrecked catamaran river barge which is right beside the place where I find the Notodoris minor:That image is a stitch-up of seven separate frames. It covers about 160°.

Since we’re doing a lot of yellow today, I’ll throw in this snap-shot of a Latticed Butterflyfish (Chaetodon rafflesi):I’d rather that the other one had gotten out of the way a little sooner. This image was the result of a ten minute chase. Butterflyfish are very frustrating.

I’ll have more weekend adventures later. They include a very nice party, a car theft by a drunk, a house invasion and possible rape (we don’t know yet) and probably some other things that I’ve already suppressed deep in my memory vault.

I’ll also have some nice shots of my peeps.*

Have Some More Fish

I’ll show you a couple of more fish from our dive on Saturday. These are not fish. This is Tom and Rob:

These, however, are  fish. Specifically, they are Blueheaded Tilefish (Hoplolatilus starcki):

You almost always see them in pairs. The never venture far from the burrow in which they hide from predators. It’s a little difficult to get close enough to get a good shot of them. This is the best that I’ve managed so far.

These little jewels are Butterflyfish. The one on the left is a Redfin Butterflyfish (Chaetodon lunulatus), and the other one is a Laticed Butterflyfish (Chaetodon_rafflesi):

Butterflyfish are surprisingly difficult to photograph. The have an uncanny ability to stay just out of range and duck behind a bit of coral just as you’re pressing the shutter release. I saw these two at a distance picking away at tidbits, a mid-morning snack. I slipped down behind a coral head, held my breath, and then slowly came up for the shot.
