The Angry Little Fish

I still have a stinking cold and I’m still trying to catch up on my posts. I’m now only two days behind. Fortunately, I got a small treasure trove of shots from last Saturday at Barracuda Point and the Eel Garden, both at Pig Island.  I’ll show you a few today and more tomorrow. Then I need to think about something else to write about, because I can only eat so much fish each week.

I’m just listening to some songs by a group called Gare Du Nord  which, presumably means “north station”. I think it refers to a railroad station in Paris. It’s got a nice eclectic jazz/rock/electronica thing going for it. I found in on my network drive for shared music.  I don’t know who put it there, but it’s got a solid groove and nice thumpy base. My sub-woofer is under my desk. I can feel the base hits tickling the hair on my legs. Funky!

Well, you’ve seen these here before, so there’s nothing new here, folks. Might as well move on. It’s a Divericate Tree Coral (Dendronephthya roxasia): 
I hit the flash on this one, since they light up nicely. The inside is like jelly and it conducts light very well.

We had a fresh diver with us on Saturday, name of Scott. I grabbed this shot of him chasing around after a mob of Bigeye Trevally:Barracuda point was crawling with big Pickhandle Barracuda and Trevally. I’ll have some barracuda shots tomorrow, if this cold doesn’t kill me.

You’ve seen this here before also, a Coral (Lobophyllia hemprichii)  [young stage] which is improbably bright:They’re like the traffic lights of the reef. Too bad that I’m a little late for Valentine’s Day. This one has a nice little heart shape in the middle.

I found some nice Palm Coral (Clavularia sp)  which is a different colour than most of what I’ve seen before. This has much more yellow in the polyps:I love to watch the stuff waving around in the current.

Here’s another familiar client of mine, the Papuan Scorpionfish (Scorpaenopsis papuensis):This character was all dolled up for a party, I think. Don’t ask my why the first name that popped into my head when I was working on this image was Rodney Dangerfield. If you don’t get it, then there’s no use explaining. I have a Harley Davidson t-shirt which is a bit obnoxious. It brazenly states, “If I have to explain it, you wouldn’t understand.” If you asked this fish, that’s probably what it would say.

There goes that bass tickling my legs again. It’s “Boogie All Night Long”. Reminds me of my Flickr nickname, BoogiesWithFish.

Here’s another familiar sight for regular readers. Lizardfish Love:Again, if I have to explain it . . .

I’ll finish up with the star of the show, this very perturbed little Spotted Shrimpgoby (Amblyeleotris guttata):As I mention in my excerpt, I’ve had fish hide from me, chase me, harass me, bite me, defecate on me, pose for me, run from me, well, the list goes on and on. After 2,000 dives, you begin to think that nothing is going to surprise you.

However, this is the first time that I’ve seen a fish simply glare at me with naked hatred.

Hey, what did I do?

More Underwater Critters

Posted in Under the Sea on January 27th, 2010 by MadDog

Well, the charter to Bag Bag Island  is off. There have been several small craft lost at sea in Astrolabe Bay  over the last few days. There’s a fierce nor’easter blowing and the chop is reported to be up to three metres. I’m poor and wild, but I’m not completely insane. The money was good, but the risk too great. As soon as I told my good friend Trevor Hattersley about the charter he called me back several times to talk me out of it. That is what good mates do. Thanks, Trev.

So, I find myself presently incomeless, but safe and dry.

Therefore, let me attempt to entertain you for a few minutes with some miscellaneous pretty pictures and some verbal rambling. This Coral (Lobophyllia hemprichii)  is not the stuff of of raw excitement, but it’s interesting to speculate how something that looks like this is actually alive:I’m reminded of the old Star Trek  episode in which the rocks were sentient, albeit slow movers.

After a few thousand dives and more time underwater than most people spend at church in a lifetime, you get to the point at which you can make educated guesses. Here’s a shot of a motion-blurred Oriental Sweetlips (Plectorhinchus orientalis)  and terror-frozen Many-Spotted Sweetlips (Plectorhinchus chaetodonoides):I knew how this shot would play out. The Many-Spotted Sweetlips will freeze for a while when it spots you. It will try to hide by pretending not to be there. “Look at me. HAH! Can’t see me, can you?” Then, as it slowly sinks in that it’s being observed, it will begin to swim away, usually without too much fuss. The Oriental Sweetlips, however, is easily panicked and makes haste to use the nearest escape route. I could see around a corner that the two fish were slowly finning in the sluggish current side-by-side. As soon as I popped my head up over the top of the coral bomie, the spotted fish froze for a moment and the Oriental Sweetlips headed for the door – thus the blurry fish image.

You’ve seen these fat slugs before. It may not sound politically correct to call them that, but that’s exactly what they are, so it’s okay:It’s a Sea Cucumber (Thelenota ananas),  a particularly pink one. They are usually more brownish. Possibly it has a fever.

Sometimes I need to show you a really bad image just so that you can see that underwater photography is a crap shoot. This is a Blacktip Shrimpgoby (Cryptocentrus polyophthalmus),  a fish which I seldom see:I knew the shot would be awful, because the fish was back in a hole and I couldn’t get close. Nevertheless, it’s the only image that I have of this species. I’m not bursting with pride.

This, however, is a nice little reef scene with a couple of male Purple Anthea (Pseudanthias tuka):When I saw these two, they were engaged in a little ritualised sparring. I snapped the shot as they were returning to their corners for a time-out. That’s why they are swimming away from each other.

Here is a perfectly beautiful image of a nudibranch that I still  can’t identify:I’m going to have to invest some money in a better nudi book.

You’ve seen these Divaricate Tree Coral (Dendronephthya roxasia)  here several times. I’ve mistakenly called them Diverticulate Tree Corals elsewhere. Gonna have to fix that:The one above is particularly nice. Good, symmetrical shape, rich colour; I like it.

Enough of the fishy stuff. Let me show you two UFOs that I caught on camera the other day. Actually there may be three, a big green one with an orange one riding on its back and a purple one up higher:

I yelled at them, but nobody came down to visit. If there were aliens aboard, they must be a snooty lot.

Of course, all that is wishful thinking. The coloured blobs are obviously lens flares caused by internal reflections within the optics of the bright orb of the sun.

Someday I’ll show you my real  UFO shots. They’ll blow you away!

Merry Christmas Tree Worm

Posted in Under the Sea on December 23rd, 2009 by MadDog

Let me begin today’s mashup of disorganised visual and verbal clutter by wishing myself a happy birthday. This has, indeed, been an interesting year. Having lived through my 66th year, I now embark on my 67th. In the past year, as a result of a New Year’s Resolution,  I have banished foul language from my daily speech (almost  completely), made an unexpected trip to North America without busting the bank and begun to reverse the devastating financial situation at Casa MadDog.

So many blessings . . .  And now, it’s almost Christmas, a time of year that inevitably depresses me. So many reasons . . . No snow or cold weather (which would probably kill me anyway) Don’t get to see my son and his family, my beautiful, smart granddaughters. Never mind. I’m not going to whine on my birthday. Eunie will bake me a pineapple upside-down cake tomorrow, a family tradition. I’ll eat the whole thing. It will take me about two or three weeks, according to how rapidly my spare tire inflates.

And now for your daily Christmas Tree. Here is a cute little mob of them:

If you move your hand over these they will disappear down their hidy-holes in an instant. No, I’m not guaranteeing that it will happen on your computer screen. Hey, I could do that with a mouse-over. I wish I had time to try it. First I’d have to have the exact same shot with the worms retracted. Never mind. I didn’t think of that while I was under the water.

Here is the star Christmas Tree Worm (Spirobranchus giganteus)  for today:I like the little magenta stars on top.

Here is another “what I actually saw” shot. The murky water at Barracuda Point  last Saturday lends a spooky effect to this shot of Divaricate Tree Coral (Dendronephthya roxasia)  with Carol Dover in the background checking out some Pickhandle Barracuda (Sphyraena jello):It’s not pretty, but it’s what I saw.

Here is something that has puzzled me for some time. We often see these Solitary Corals, sometimes called Mushroom Corals, with damaged edges and colourful stains. This one is a deep form, that is it grows in deeper water, of Fungia fungites:If anybody out there knows anything about this, please enlighten me.

The contortionist of starfish is Choriaster granulatus  or, as we sometimes call it, the Dirty Starfish. I’ll let you wonder why:Another common name for this one is the Granulated Starfish. I don’t know how they manage to squeeze themselves into such awkward positions. This one looks as if it is trapped under a coral ledge.

Sticking with water, but on the surface now, here is yet another water drop image:

My fascination with water drops is boundless.

I wonder what that means?

Reef Scenes – The Magic Kingdom

Posted in Under the Sea on December 14th, 2009 by MadDog

It has been a joy over the last few years to get truly into the digital age of photography. Having learned the smelly-chemical method before I was twelve years old, I stuck to the film media for several years after the first digital cameras. I had inadvertently joined the massive ranks of ’serious photographers’ who were shouting down digital cameras of the time as playthings not worthy of the art. They were  pretty miserable at first. My first digital was a 1.3MP model which was okay for snapshots, but inadequate for anything else.

One of the great frustrations (among many) of shooting underwater on film was that I could never, except by dumb luck, get an image to look the way that I saw it with my own eyes  – in other words – natural.  I have discovered, especially in the last year or so, that the secret lies in the techniques used. I’m not going to bore you with all that. If you’re interested, I’ll trade all of my secrets for a case of beer. It’s not a big deal.

However, it does give me severe pleasure to present to you images that look exactly as the diver (me) saw them, or at least as close as I can get. For instance, you often see close-up shots here that are products of careful shooting and laborious processing with Photoshop. The truth is that we seldom actually get that close. Here is a more normal diver’s eye view of a Spot-Tail Butterflyfish (Chaetodon ocellicandus):Spot-Tail Butterflyfish (Chaetodon ocellicandus)It may not be spectacular, but it’s what the diver actually sees. If you are going to get any closer to this little butterflyfish, your name had better be Houdini.

On the other hand, it is sometimes nice to get close. These polyps on a Sea Fan (Acabria sp.)  seem to be a white mass from a metre away. It is only when you get close that you can see their flower-like beauty:Sea Fan (Acabria sp.)It shots such as this, getting the colours right is the most difficult part of the job. When I can sit back and think to myself, “Yep, that’s just as I saw it.” then I know that my work is done.

Here is a group of Purple Anthea females (Psudanthias tuka)  with stalks of Whip Coral (Sea Whip – Junceella sp.)  in the background:Purple Anthea [females] (Psudanthias tuka)The colouration of the Purple Anthea is problematic. In most cases, they do look purple in colour. However when viewed with the light at a different angle, they often appear more blue, as in this image.

Here is a beautiful Divericate Tree Coral (Dendronephthya [Roxasia] sp.)  with more Sea Whips in the background:Divericate Tree Coral (Dendronephthya roxasia)It is such a pleasure to sit back after fifteen or twenty minutes of work and say, “Uh-HUH!  That’s just the way it looked to me.”

Here is another coral species that has been a bother to me for a long time (Tubastraea micrantha).  It is a deep, deep forest green colour and is found only below about twenty metres where the light is beginning to dim to shades of blue:Coral (Tubastraea micrantha)It is devilishly difficult to get the deep green colour without trashing all of the rest, even with Photoshop. This is the best that I have managed so far. It came at the cost of desaturating much of the surrounding area. However, I can attest that the colour that you see on the coral itself is exactly as I saw it. Just ignore the stuff beside it.

Another type of image that I enjoy capturing is the community as a whole. Here is a little anemone garden featuring the Tomato Anemonefish (Amphiprion frenatus).  These are females. The male, in this unusual case, is much less pretty, being more or less solid light orange:

Coral Reef Community with Tomato Anemonefish (Amphiprion frenatus) [female]
It’s such a thing of wonder to glide up over clump of coral and look down on a beautiful scene such as this. I can’t imagine ever tiring of it.

Your mileage may vary.

The Secrets of Leper Island

Posted in Under the Sea on December 7th, 2009 by MadDog

There are, so far as I know, no secrets of Leper Island.  I’m just reaching for a title. There’s little mystery concerning it, other than the fact that there were no lepers on Leper Island  (they were actually on nearby Pig Island  or Tab Island  as it is more properly called) . Yes, the lepers were on Pig Island  and Leper Island  was the place where they raised pigs to feed the lepers. Confused? Join the club. I got that information from Tamlong Tab, a man who should know.

What has all that got to do with today’s malarkey? Absolutely nothing. I’m just filling space here. Anyway, here are the lovely Finisterre Mountains  in the background with Leper Island  on the right and Little Pig Island  (which also has another name, but I can’t remember it now) on the left:

Finisterre Mountain Panorama
The big strip of land in the mid distance is Kranket Island.

We had an excellent dive in a spot on the North end of Leper Island  on Saturday. I hadn’t dived this spot for some time, so I had forgotten how rich it is in coral species. Here is a Porites  coral with a couple of very nice Christmas Tree Worms (Spirobranchus giganteus):

Christmas Tree Worms (Spirobranchus giganteus)

That’s probably my best Christmas Tree Worm shot yet. I’m very happy with it. To give you an idea of the scale, the two worms together would be about as wide as the width of your eye.

This flaccid looking spiky thing is a Divaricate Tree Coral, (a species of Dendronephthya (Roxasia)):

Divaricate Tree Coral (Dendronephthya [Roxasia] sp.)

These things are fantastic at night. I think that the structure must be similar to optical fibre. If you shine a strong light into the base, the whole thing lights up like some kind of crazy lava lamp.

I’ll throw this bone to the coral freaks out there and hope that I’ve identified correctly. I’m not positive about the Acropora cerealis  in the foreground, but I am pretty certain about the Seriatopora hystrix  in the background:

Coral - Acropora cerealis (foreground), Seriatopora hystrix (background)

I need to find myself a better invertebrates resource. My book is pretty thin.

This is the Common Lionfish (Pterois volitans):

Common Lionfish (Pterois volitans)
They are usually fairly imperturbable. It won’t move much unless you poke your camera (not  your hand) right in its face and waggle it around. You’d be imperturbable too, if you had thirteen very poisonous spines sticking out of your back. This one, however, got into some kind a weird panic that I haven’t seen before. It started running away from me. When it swims fast, the delicate feather-like fins wave like pennants in a most beautiful display of the flight response. In the shot above, it is just about to swim under a ledge of coral.

In the morning we had all been complaining how hot it was. While we were down on the dive, I noticed that the light was getting dimmer. When we approached the surface we could see that rain was pouring down:

Raindrops from belowIf you click to enlarge, you’ll see some tiny little splash rings where individual drops are hitting the surface of the water.

When we got back on the boat, the temperature had dropped about ten degrees C. Now we were all complaining about being cold.

Spome people are never satisfied.

A Dog’s Breakfast of Images

Posted in Humor, Mixed Nuts, Under the Sea on October 22nd, 2009 by MadDog

a dog’s breakfast: British slang for “a complete mess” has been in usage since at least the 1930s. While no one took the time to write down the exact origin of the phrase, the allusion involved seems to be to a failed culinary effort, perhaps a burned or botched omelet, fit only for consumption by the mouth of last resort, Fido.

It’s been one of those days. Today I have (1) consulted with business associates concerning the establishment of J & E Enterprises Limited, (2) consulted with the Investment Promotion? Authority concerning whether or not the company is a “foreign” company, (3) adjusted our organisational chart so that it isn’t, (4) appointed a new director, (5) fixed a radio transceiver [unsuccessfully], (6) filled out many forms on which were printed questions which I did not understand (faked it), (7) tried to get another transceiver working [still out on that one], (8) tested a solar panel and battery, (9) ate lunch [five minutes while visiting BoingBoing], and it’s only 14:56.

That’s why I get the big bucks. (In my dreams.) Now, I’m staring at an empty page.

So, I’ll throw in your general direction some images that don’t seem to belong anywhere else.

This is a Bird of Paradise flower. Okay, okay, the whole thing is not the flower. The flowers themselves are only the little ‘molars’ of the dinosaur’s lower jaw, which is what it really  looks like to me. The big tusky things on the left are it’s . . . er . . . tusks.  I don’t know what the big white thing on the right is, maybe a thighbone of a human, who, according to some, were wandering aimlessly around contemporaneously with the dinos:

Bird of Paradise Flower

That being disposed of, I’ll now show you a Ship of Fools sort of image. An improbably tiny ship in a big, improbably blue sea under a surrealistically improbable sky. Don’t stare at it for too long:

Sunrise and Ship

I have to admit that I’m overly fond of this one. I showed you a similar shot a time ago. I just got around to working on this one. I had to do surprisingly little to it. The Canon G9 did a fine job all by itself. It’s the moon (didn’t notice it, eh?) rising across the harbour from our house:

Moonrise over Madang

Under the surface of Mama Ocean we are forever seeing blobby or spiky or weird things about which we have not a clue. This one caught my attention last Saturday and I decided to investigate it carefully instead of dismissing it as “sea goo”. As I was looking it and photographing it, I still didn’t know what it was. It’s about half the size of my hand:Juvenile Diverticulate Tree Coral (Dendronephthya roxasia)It wasn’t until I got the image up on my computer that it clicked and I realised what I’d been looking at.

Hah! It’s a juvenile Diverticulate Tree Coral (Dendronephthya roxasia),  as any fool can see:Diverticulate Tree Coral (Dendronephthya roxasia)The shot above is similar to one that I showed to you a few days ago. (Except better.)

That mystery now having been solved, I must return to the work for which I receive what is laughingly called “pay”.

To Flash or Not To Flash – That Is the Question

Posted in Photography Tricks, Under the Sea on October 19th, 2009 by MadDog
No Gravatar

Yes, you have guessed it. I am going to bore you once again with the topic, “Whether to Flash or Not?” This is a matter of little import to those who do not regularly submerge their precious cameras in high-pressure saltwater, something which surely violates fundamental laws of nature and sanity.

The vast majority of people snapping away today depend on their cameras to decide whether to flash or not. I am against this notion, since it produces countless nasty-looking photos Alas, I am a voice crying in the wilderness. My word on the matter is simple:  Learn how to make the flash on your camera submit to your will and then learn when you need it and when you’d get a getter image without it. Many people have thanked me for this entirely unsolicited advice. Your mileage may vary.

So, what’s the big deal underwater? Who cares?

Well, you do care, if you are interested in seeing what a given critter actually looks like underwater. If you just want a pretty picture with bright colours, then you turn on your flash and you will have far less work to do on your computer to get a usable, if misleading image. I usually want my images to display to you what I saw. Here is (yet another) example, a Divaricate Tree Coral (Dendronephthya roxasia):

Divaricate Tree Coral (Dendronephthya roxasia)

I think that it is quite pretty as it is. Moreover, it is exactly as it appeared to  me when I saw it at about 25 metres at Barracuda Point,  which is lousy with the things.

From the same position, I took this image with the flash turned on:

Divaricate Tree Coral (Dendronephthya roxasia)

Well, that too is a pretty image, but it’s not what I saw. One has to remember that, the deeper you go, the less of the spectrum is left. Only blue and a little greenish light penetrate more than a few metres. So, everything looks blue. Your eyes magically adjust to most of this and restore some balance. However, when you add the sunlight colours of the flash, which is designed to mimic sunlight (its colour temperature), then you completely upset the colours which are displayed in the resulting image. In effect, you have shown the object as it would appear at the surface.

Here’s another one:

Palm Coral (Clavularia sp.) - Available Light -

That’s a Palm Coral (some species of Clavularia)  which has appeared here before. It was shot in with the natural lighting. Check the delicate green shades in the centres, especially around the edges of the clump, where the exposure is a little less. This is a very pretty coral with delicate nuances of colour.

In this flash shot that I got last Saturday for comparison, the nuances are overpowered by the sunlight-white light of the flash:

Palm Coral (Clavularia sp.)

All of the pretty greens are lost.

Here is one more example. This one is a little harder to justify. This is our old friend and regular on Madang – Ples Bilong Mi,  the Spotted Shrimpgoby (Amblyeleotris guttata):

Spotted Shrimpgoby (Amblyeleotris guttata) - Available Light

For comparison, I made one exposure with natural light and one with flash. By now, I’m sure that you can see the difference. The shot above is flash-less.

This one is with the flash turned on. Again, it is not an unpleasing effect. In this case, it does score some points. Because it intensifies the colours that are the distinctive markings of the fish (primarily the orange spots and the dark pectoral fins, not to mention the clown-like eyes), it helps one to remember the primary identification features:

Spotted Shrimpgoby (Amblyeleotris guttata) - Flash

If you memorise the image above, you’ll have no trouble identifying the species when you are cruising over the sandy bottom.

You just have to remember that the first example image, without the flash, is how it is actually going to appear.
