Blurry Fish and Barrel Sponges

Sometime I like amuse myself by going back through my accumulation of thousands of underwater images to find the ones which I first rejected as real.  Usually this rejection has to do with some technical fault such as bad focus (usually an image-killer), impossibly filthy water (sometimes fixable by laboriously removing the spots) or motion blur. Of the faults, motion blur is the easiest to turn into art. It sometimes generates a very interesting image. Here is a Many-Spotted Sweetlips (Plectorhinchus chaetodonoides)  which I tried to capture with a shap shot at Magic Passage:

The attempt, as you can see, failed miserably. Both the fish and the background are blurred. Nevertheless, a tiny, nagging tickle in the back of my skull kept mumbling, “Play with it, idiot.” I always pay attention to these messages from my id. As you can see, with a little work, the wasted pixels redeem themselves. A mistake becomes art. I don’t know if I’d want to hang it on the wall, but it provided me with a few minutes of not  thinking about computer networks. That’s a blessing.

Here is another one that I saved from the bit dumpster. The Silver Sweetlips (Diagramma pictum),  one of my favourites, hangs out in mobs at Magic Passage. You can find many more images of them here on Madang – Ples Bilong Mi by putting “pictum” in the search box. Is is a very beautiful fish:You can see in the shot above that the background is relatively unblurred (relatively, as I say) but the fish was moving quite smartly. This transforms the beautiful yellow spots of the sub-adult into concentric yellow arcs which give the image the impression of some kind of weird, mustardy fingerprint. Fingerprint? Okay, let me reboot . . . nope, still reminds me of a fingerprint. What can I say?

At any rate, a strange piece of chintzy art is better than wasted pixels. I might actually hang this one. No, wait. I’m far too lazy.

Here’s a shot of the Silver Sweetlips sub-adults hanging in the current. These are very chilled-out fish:

They gang up like sulky teenagers on the corner by the liquor store, waiting for some sucker to buy them a bottle. I’m sure that if there were an equivalent of Mary Jane for fish, this mob would be toking up.

I did mention something about Barrel Sponges.

Here are two Barrel Sponges (Xestospongia testudinaria)  at Magic Passage, right in the area of the highest currents:
When Barrel Sponges get really big, they are very heavy and present a huge surface area upon which a strong current can push. It’s not surprising that they occasionally get knocked over. Here you can see one that is hanging on and one that has been toppled. Not to worry, the severely tilded sponge can continue to grow. When knocked down like this, the sponge continues to try to grow up towards the light, so some of the ones which have been over on their side for a long time have very peculiar shapes.

I’ll wrap up with this anemone with one little anemonefish guarding it:
I have one hour left to load the boat and get to the pick-up point for our regular Saturday dive. I’m outta here.
