I’ll keep the babble at a minimum today, as my brain is running on empty and I’m moving at molecular speed though I have my mental pedal to the metal. In case you’re interested in the gory details, my sinuses are expanding exponentially and will soon be causing grey matter to ooze out my ears. It makes it even harder than usual to think. Oh, I can still think about a lot of things, – no worries there. The problem is that none of them are useful.

This does not bode well, as I have a very important appointment tomorrow, the outcome of which will have a huge effect on the next few years of  our lives. I’m sincerely hoping for a clear brain in the morning, if not clear sinus cavities.

I see that I’ve already exceeded my babble limit, so I’ll get right to this cute little Clark’s Anemonefish (Amphiprion clarkii) guarding his host with due diligence:We used to see a lot of this species, but lately they seem to be getting more scarce. This always worries me when I note changes in species distribution. I don’t have enough technical knowledge to know if it’s important or not and I’ve had no luck, so far, in interesting any marine researchers to return to Madang, which used to be one of the main playgrounds for such eggheads.

Yesterday, if my memory is working correctly (no guarantees) I showed you another of these corals of the Galaxea genus:They are particularly beautiful and incredibly detailed. This one is the Galaxea fascicularis. It’s worth clicking on to see the detail of the polyps.

This shot is a bit of a double treat. The kicker is that I found it right under the bow of Faded Glory. We anchored in the sand, but the boat drifted a little over the top of the reef. I caught this just as I was returning to the boat. It’s a pair of seldom-seen Skunk Anemonefish (Amphiprion akallopisos) lurking in a similarly rare and beautiful Merten’s Anemone (Stichodactyla mertensii):Quite a nice surprise at the end of a painful dive.

Going back a couple of days, I showed you this same Nudibranch (Phyllidia varicosa) shot with natural light. As I was going through the images from that day I noticed that I had also taken flash exposures of it. For the first time in a long while, for a macro shot, I think that I prefer this flash shot to the natural light exposure:I think that the explanation is that the light was poor and I had to do a lot of fiddling with noise and a bit of motion blur to get the shot by natural light. This one has much more realistic detail. I didn’t even bother to give it a bath to remove all of the little bits of ocean gook that usually cover everything.

Here’s another fish that you saw recently as a part of a pair. I found this side-on shot of a Split-Banded Cardinalfish (Apogon compressus) which I had previously rejected because I thought that it was over exposed:As it finally turned out, it is not a bad specimen shot, except that the intense blue of the eye is lost. Someday I’ll get the perfect shot of this fish.

Okay, I’m falling out of my chair now. I think I’ll go home and go to bed. I have computers to work on, but my brain is rebooting every time I think of that. It’s taking much longer to come back on line.

This last Saturday was a banner day for photography. My new Canon G11, which you are undoubtedly getting tired of hearing about, was perking along nicely, grabbing shots with much increased dynamic and no noise whatsoever at ISO 80. The ten megapixels that it offers are more than sufficient for the magazine-size shots that I need to do my work. Don’t sniff at ten megapixels. If another camera offers more, but the resulting image is poorer in quality, what good do those extra megapixels do?

Yesterday’s post contained images from this Saturday’s dive also, as will tomorrow’s and the day after. In total, out of about one-hundred exposures, I got thirty-six which I deemed good quality. I’ve never had a two dive day that was more productive. Part of the reason for that was that my old buddy, Richard Jones, was “spotting” for me. He has amazing eyes and can find the smallest critters. Sometimes these are the most interesting. Tomorrow I’ll feature some nudibranchs which Richard found. Your mind will be blown.

But, that’s for tomorrow. Today, we’re doing colours. The dive at Planet Rock  was dark. There was a layer of muddy fresh water from the Gol Gol River  floating over the surface down nearly to the top of the sea mount at about 15 metres. I had to take many shots with flash. Though it is my preference to forgo flash when possible, sometimes it is unavoidable – there’s simply not enough light. In the first two shots, the effects of the flash are not noticeable. It simply acted as a fill light. In the others, the effect is dramatic, though the colours are, to me, artificially bright. They are, however, very pretty.

Green has been my favourite colour since I don’t know when. When I was a small child, it was red. I don’t know when I changed to green. I don’t even know if guys are supposed to have a favourite colour. I don’t talk about it much over the pool table with my mates, though I’m always soothed and mellowed by the green playing field. Maybe that’s why I’m such a lousy shot. Anyway, have a look at this lovely green Coral (Acropora tenuis):Click it to magnify and see the lovely details of the polyps waving in the current. Each little ledge on each tower is an individual animal. It is truly a thing of beauty.

Here’s another Acropora  species with a dramatically different colour:I’m always faintly startled when I run across one of these outlandishly purple corals. They seem somehow out of place. I wonder if a nearby toy store exploded and scattered misshapen shards of bright plastic on the sea bottom.

This shows why we have a pretentious name for the Magnificent Anemone (Heteractis magnifica).  You can see a scattering of  Pink Anemonefish (Amphiprion akallopisos)  chilling out and having a few beers:What a lovely playground they have.  There are few sights in the sea which are as calming and wondrous as this symphony of colour displaying a commensal relationship between vastly different organisms. Neither can flourish without the other.

Starfish fans will enjoy this lazy looking Linckia laevigata.This is the same species which often appears as a bright blue variation.

This Coral (Lobophyllia hemprichii)  contains the brightest red pigment of any creature that I have seen in the sea:This is a very young colony. They tend to become less colourful as they grow. Young ones, such as this, can often be seen as tiny crimson torches thirty metres away on a day with good visibility.

I’m a great fan of Feather Stars. This is a particularly nice image of some species of Lamprometra.  They are difficult for me to tell apart. I’ve been watching old episodes of Fawlty Towers  during the fifteen minutes that I can stop working each day. I can’t get out of my mind what Manuel (he’s from Barcelona, you see) says when he misunderstands a command from Basil Fawlty: “Eet ees deefeecult.”You can clearly see the “feet” of the feather star in this shot. If you gently tickle a foot with your fingertip, the creature will wildly thrash its arms around, waving madly. It’s a most comical sight. I’m going to have to shoot a video clip of it some day.

Here is a close up shot of another individual of a Lamprometra  species Feather Star:I didn’t think that the shot would turn out to be much. Now I’m simply blown away by it. Beware. If you stare at it long enough you may feel yourself getting slightly high, that is if you recognise “high”. Click on it to make it bigger and have a look. It’s mesmerising. This is a living thing. How can that be?

I don’t recommend it as a desktop background.

Text will be terse today, as I am swamped by work in the computer room. Everybody needs everything right now.  It’s not something that system administrators are not used to. It does get a little irritating when you’re also trying to roll out an entire new network at the same time.

Enough complaining. Let’s have some fish.

This cute little critter with the improbable beard is, of course, a Goatfish – what else would you call it? Specifically, it’s a Manybarred Goatfish (Parupeneus multifasciatus):

The whiskery things are used to find food. It digs around in the sand for a meal. As you watch, you can see the whiskers flying around like mad. It’s speculated that they are extremely sensitive to the electrical fields around living things. Spooky, eh? I wonder if weapons researchers are checking into this.

This little one has the delightful name of the Pink Anemonefish . How harmless does that sound? If you’re on more formal terms it’s (Amphiprion akallopisos):

Everybody knows that this is a Moray Eel (Gymnothorax javanicus).  What you may not  know is the it is the wrong colour.  This is another reason that I’m always whining about the use of flash for underwater photography. The eel looks nothing like this with the naked eye in natural light: Compare it with these images taken with available light here, here, here and here. This shot was too deep for available light. I had no choice but to use flash.

Steven Goodheart sent several very nice nature shots, but I could not get any but this one to load properly. It’s worth a solo appearance. It is, as Californians will recognise, a Western Fence Lizard (Sceloporus occidentalis):

This is a particularly nice shot for identification and I like it because the composition is also very clean.

And now, because I never tire of seeing myself on the silver screen, I’ll show you this shot of me at Blueblood with our missing friend Heidi Majano:

As is usual with most keen photographers, we hardly ever get an image of ourselves that we really like. This one tickles me. Put “heidi” in the search box in the sidebar to see some of her great images.
