Sunday at the Office

Wooo Hooo, I just LOVE driving all the way to work on Sunday morning to do a post because swampsucking TELIKOM can’t figure out how to twist two wires together so that somebody can get an actual dial tone for more than two hours. However, it does produce the occasional side-benefit. Witness this lovely, if somewhat sombre, morning scene at Coconut Point:The water was all sparkly and the sky looked like it had just dropped some acid. Very trippy, indeed.

Speaking of trippy, I showed you some Blue Coral (Heliopora coerulea)  in a mixed bag of things that I picked up on the beach. It took me a long time to figure out where it came from. There’s nothing that looks like it underwater. Then I discovered that it is actually brown on the outside. I began looking around for the right stuff and finally found a little bit that had been broken off. On Saturday’s dive, I found a big spot where something, probably a clumsy diver, had broken off a couple of knobs:As you can see, it’s improbably bright blue inside. I’d be interested to know what causes this blue colouration, but I’m far, far too lazy to research it. The beach at Wongat Island  is covered with the stuff that has been broken up by natural means and washed up and tumbled. That’s what you see in the image to which I’ve linked to in the paragraph above. The image here is the live stuff that has been broken off.

I simply love these chubby, cuddly looking Starfish (Choriaster granulatus).  They are the puppies of the Starfishes:I noticed that this one was particularly pink, especially in the centre. The do vary somewhat in tint. The posture here is suggestive that it’s leaping over the boulder with its arms outstretched, probably hollering “Whoopee!” Don’t believe it. Their top speed is about a half-metre an hour.

Here’s some very gaudy female Purple Antheas (Pseudanthias tuka)  flitting around at the local mall:The male is around somewhere, probably near the edge of his harem, keeping an eye out for poachers.

I showed you one of these nightmarish Sea Cucumbers (Bohadschia graeffei)  a few days ago:This is a much better shot. It clearly shows the sucker-like food-gathering thingies that reach out continuously and grab onto anything remotely edible.  As soon as one of these appendages has sucked something up, it bends around in a particularly creepy fashion and shoves itself down into the gob of the squishy, prickly, disgusting critter.

You’ve gathered by now, I’m sure, that this is not among my favourite creatures of the sea.

Nightmare From the Sea

Well, I am again today trying to get caught up. I can’t really speak, since my voice box seems to have malfunctioned. I got a call from California today, pretty important call, but I had to give up and say I just couldn’t do it. Try again tomorrow. Fortunately, there’s nothing wrong with my fingers – yet.

I’ll continue today with a few more shots from last Saturday’s dive at the Eel Garden. Some of the critters you’ve seen before. These are different angles or show different features. For instance, I showed the the ugly mug of the Papuan Scorpionfish (Scorpaenopsis papuensis)  yesterday. Care for a game of “find the fish”? It’s not to difficult with this one. It was having trouble matching the leather coral on which it was lurking in wait for a meal:I’d really love to see one of these catching a fish. I’ve read that it’s one of the fastest actions in the animal kingdom. I imagine that all that I would see would be a puff of “dust”, probably accompanied by a loud popping sound.

I don’t often bother with most of the damslefishes. Except for a few, such as the anemonefishes, they’re not particularly pretty. However, I do like this shot of a White-Belly Damselfish (Amblyglyphidodon leucogaster):It’s one of the few shots that I have in which the image actually is prettier than the fish itslef.

You saw these two Reef Lizardfish (Synodus variegatus)  yesterday. Here is a shot of them from the side:It’s amazing how often one sees them in pairs.

You have seen a lot of images of these Solitary Coral (Fungia fungites)  here before. This one is unusual because of the white stripes. I can’t find any reference to this differentiating between species, so I’m guessing that it’s some kind of “sport” or mutation that’s not harmful to the individual. Any other guesses out there?It is not an uncommon sight, as is the purple stain that you can see at the top. I’ve seen these bright colours before on these corals.

Butterflyfish are extremely exasperating to photograph. I have very few good shots. This Spot-Tail Butterflyfish (Chaetodon ocellicaudus)  blasted past me at full throttle and I just pointed the camera and pressed the shutter release:Talk about a lucky shot!

Today’s nightmarish feature is this Sea Cucumber (Bohadschia graeffei):The body extends to the right, where you would find the stinky end, if you cared to look. I don’t want to think about what comes out of there.  The worst part is the end at the left, which is the consuming bit. I wouldn’t use the word “eat” to describe what this thing does. It engulfs, it vacuums, it . . . sucks!  The frilly black things with white edges are constantly reaching out, gluing themselves to anything remotely digestible and then shoving them down the ugly gob of this, this . . . thing.

Fortunately, it doesn’t move very fast.

A Good Spotter Makes All the Difference

Posted in Under the Sea on February 9th, 2010 by MadDog

Since my good dive buddy Richard Jones got bent a while back he has not been able to dive, until recently. He finally got an insurance company to cover him down to 18 metres. So, when we go diving, we stay shallow and enjoy the best that the reefs have to offer. This is good news all around. Rich is back in the water, we are more or less confined to the best part of the reef for photography and Rich has eyes like an eagle.

Rich and I have had some great diving adventures together and I’m so glad to have him back on Faded Glory.  He also has just purchased a Canon G11 and housing, so I’m expecting that a competition will soon begin. He is a nudibranch freak. Get ready for a steady diet of rare nudis. Yum, yum.

Here’s a shot of Rich on our first cooperative, “I spot, you shoot.” dive:

Notice him giving me the “come hither” signal.

The first thing that we saw when we got off of the boat in pretty miserable conditions, with dirty fresh water from the Gol Gol River  over us was this lumbering Sea Cucumber (Thelenota ananas):Pretty is not a word that I would use to describe these alien critters.

I think that this must be some kind of algae, although the colour looks highly improbable:It really is as purple as it looks. It waves around in the current like silky hair. I thought that there was a slim possibility that it was a clutch of nudibranch eggs, but nothing that I can find matches it. After Googling for a few minutes, I gave up. Anybody have a better idea? I also tried “purple marine algae”, but no luck.

We see giant Barrel Sponges all the time. However, we seldom see small ones. It’s the old, “Where are the baby pigeons?” question. Here is a shot of a very young Barrel Sponge (Xestospongia testudinaria):It is only about the size of your fist. The big ones can be the size and weight of a Volkswagen. There is a Squirrelfish or Soldierfish of some kind peeking at me from below the ledge. I can’t see enough of the body to identify it.

This poor crab was somebody’s dinner. All that’s left of him is one claw:It’s amazing that we see so little evidence of the nightly carnage on the reef.

I snapped this quick shot as a school of Narrow-Stripe Fusiliers (Pterocaesio tessellata)  with one Blue and Yellow Fusilier (Caesio teres)  flashed past me. It’s a credit to the G11, not to me, that the image came out looking as good as it does:Not a wall hanger, but you can identify the fish.

Finally, here is a nasty-tempered Moray Eel (Gymnothorax javanicus):This grumpy customer kept sticking his toothy face right out at me. If he looked as if he were going to bite, I’d just bump his nose with my camera, not hard, just enough to make his teensy-weensy brain reboot. He’d pull back in his hole and sulk for a few seconds and then peek out again. No harm – no foul.

I know that I’m going to get bit some day. Ah, well, a few more scars. It just adds to the legend (in my head).

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!

Underwater Photography – Abort, Retry, Fail

Posted in Under the Sea on January 4th, 2010 by MadDog

Back in the Bad Old Days of MS-DOS, if you were working with computers you would see, probably once an hour (it seemed so, anyway) the unhelpful message on your screen: Abort, Retry, Fail.  None of these three suggestions were ever of much help. It was Microsoft’s way of saying, “That’s not gonna happen, man.” Yeah, sure, you could usually figure out what was causing the problem, but most of the time there wasn’t much you could do about it.

You’ll be happy to hear that there is a way that you can once again experience these excruciating moments:  through the magic of underwater photography. I’ve collected a little gallery of horrors to illustrate a few of they infinite things that can go terribly wrong. I hope it amuses you, as an observer, more than it does me, as a practitioner.

SUBJECT RUNS AWAY

I wanted, longed, deeply desired, the moment that I saw this fish to capture its soul in digital bits. Sadly, the job is botched. This is a rather rare yellow colour variation of the Blackspotted Puffer (Arothron nigropunctatus):

When I say rare, I mean that I have never seen this species with as much yellow on its body. It really is a beauty. This one, as you can see, was at a cleaning station – it’s like a car wash for fish. The underpaid and little appreciated workers in this car wash are the little cleaner-fish, one of which you can see here vainly chasing the Puffer in hopes of gobbling a few more parasites from its skin. You can see the little Bluestriped Cleanerfish trailing along behind. These little puffers run away (probably screaming in fishy terror) as soon as anything big approaches. They don’t swim very fast – just fast enough to spoil the shot.

The observant observer will note that the image is spoilt by motion blur. I was trying to pan the camera to follow the movement of the fish, which should have produced a reasonably sharp image of the fish with a motion blurred background. As it happens, I got it half right; both fish and background are blurred by the camera movement. I’m putting this one in the RETRY category. The big problem is that I may never see such a magnificent specimen again.

SUBJECT LOOKS PRETTY UNDERWATER – TERRIBLE ON THE SCREEN

These little Striped Catfish (Plotosus lineatus)  looked ever so pretty fluttering in the lazy current along the bottom at the Eel Garden close to Pig Island  on Saturday:However, the finished image is sadly lacking any interest whatsoever. You had to be there. As soon as I started working with the image I realised that the magic was in the motion. You can’t truly capture motion in a still image. I’m putting this one in the FAIL category.

SUBJECT IS A CAMERA TEASER

This juvenile Midnight Snapper (Macolor macularis)  is a pretty cool fish. They don’t look anything like the adult, which is a big brown lump of a thing. However, cool or not, this fish is a nightmare to photograph. Like many fish, it has an inbuilt standoff distance or “comfort zone” which you can, under no circumstances, violate. If it could talk, it would be saying, “Back off, Jack!”:

I did manage to get this rather pathetic shot from about four feet away with the flash turned on. It was as close as I could get. Apparently not many photographers have done a lot better. I Googled for images of this species and didn’t find anything much clearer than the shot above, except for images that were obviously shot in aquariums. I’ll let this one pass with a RETRY.

SUBJECT DARTS AROUND FRANTICALLY

This rather uncommon species, the Red And Black Anemonefish (Amphiprion melanopus)  swims spasmodically back and forth in its host and never even gives you an adequate opportunity to frame the shot. If fact, you’re lucky if the fish is even in the frame  when you push the shutter release. I only barely managed to catch it in this shot:This is compounded by the confounded shutter lag that is common in point-and-shoot cameras. I’d guess that the Canon G10 I’m currently using waits about a third of a second before capturing the image after I press the shutter release. So now, you have to guess where the fish is going to be during your next eye-blink. It’s like guessing which kernel of popcorn will explode next. This one can only be a RETRY.

SUBJECT DOES SOMETHING INAPPROPRIATE

Sometimes you just get a surprise. I would not ordinarily take a picture of an animal defecating. It’s simply not that interesting unless you’re a kid obsessed with scatological humour. We were at the deep end of the Eel Garden’s sandy slope where I was shooting the Red and Black Anemonefish when my dive buddy Carol Dover directed my attention to this big Sea Cucumber (Thelenota anax):

As you can plainly see, it was enjoying a nice, leisurely, satisfying poop. Without going into the unsavory anatomical details, I’ll simply point out the you can clearly see where the poop came from. There’s quite a bit of it, since the critter eats about 99% sand and digests only the digestible bits. All the rest comes out as tidy little sand sausages.

I’m putting this one in the ABORT category.

Wrapping Up 2009

Posted in Under the Sea on December 31st, 2009 by MadDog

After yesterday’s dark and whiny rambling through the back alleys of my nearly comatose mind, which prompted friends to call to see if I was planning to depart post-haste to greener pastures (or no pasture at all), I should maybe craft some slightly more upbeat prose. As a recovering (seemingly forever) bipolar, I need to be reminded once in a while that things are never so dark as I may wish to paint them on a down day. The flip side of that, as those who’ve experienced that hideous roller-coaster will instantly proclaim, is that things are never so bright either.

But, never mind. I’m over that. My craving for sympathy is satiated and I still have plenty of pineapple upside-down cake left. Today we will meet a couple of new characters and visit again with some old friends. A few days ago I took KP Perkins for her first dives after the completion of her Open Water Course. On our second dive, we went to The Eel Garden near Pig Island.  There, on the sandy bottom I got this pitiful shot of what we call a Leaf Fish. The “book” common name is Peacock Razorfish. This the juvenile phase of a species variation of Iniistius pavo:It’s a funny little thing. Against the creamy white bottom it looks very dark brown. I had to squeeze very hard on the lemon to get a bit of detail out of the body. Tha’s why it doesn’t look like a very good picture. We call it a Leaf Fish because, unless you are looking for it, you will be fooled by its colour, shape, the little topknot looking like a stem and its insane wobbly swimming motion into believing  that it is a leaf.

Here is another new something for you. It’s a coral, but I’m unable to determine the species name, since I can’t find it in my book. So, I’ll just call it Spiral Coral for now:What intrigues me about this coral is the striking resemblance between this overhead view and images of the Belousov-Zhabotinsky (BZ) reaction. Say what? Well, it’s a famous family of oscillating chemical reactions which can create amazing visible spiral patterns such as this:

I wouldn’t care to claim that I understand these reactions in anything other than a very general way. The details were not covered in CHEM-101 forty years ago. Nevertheless, the images were still im my mind and I could look them up with “spiral chemical reactions” using Google images. Ain’t the web great? Anybody can seem like an authority on anything. Wait, maybe that’s not  so great.

Well, here’s a spiky old friend from only a few days ago. It’s a Sea Cucumber (Thelenota ananas):I’m sure that it’s the same one that I showed you before. It lives there.

Here’s another old buddy, the gorgeous Tomato anemonefish (Amphiprion frenatus):It this shot you can see the strong blue tint that is often seen in the white vertical bars. I’m not sure if this is really pigmentation – it doesn’t appear to be so. I think that it either some sort of reflection of the sky (it seems to be more common on a sunny day when most of the sky is blue) or it is a property of the surface of the skin similar to butterfly wings that produces colour by means of optical effects at the nanometric level. But, who knows? Maybe God just paints it that way. I’m no expert.

Here’s another bit of underwater eye candy that you’ve seen here before. They are Sea Squirts (Polycarpa aurata):I like to think of them as elf shoes. See, they have nice little elastic bands around the ankles so that they won’t fall off in the midst of mischief-making.

This is a shot that I really like. It’s our old friend, the Spotted Shrimpgoby (Amblyeleotris guttata)  way out at the end of his front porch:They usually stay right next to their hidey-hole. It’s rare to see one that doesn’t have its tail down the burrow. This one has strayed a few centimetres away. You can see the trail of “dust” that it kicked up when it last came out only a few seconds ago.

I had one chance at the shot above before the little spotted pixy dived back into its burrow. The image turned out perfect. Though it’s not colourful, it is exactly as I saw it.

That is as close to diving as I can get you unless you’re ready to get wet.

Hungry? Have a Delicious Sea Cucumber (Bêche-de-mer)

Posted in Under the Sea on December 22nd, 2009 by MadDog

On Saturday, our regular dive day, we went to Barracuda Point,  on the eastern side of Pig Island.  The water at the surface was filled with particulate matter, but below about twenty metres, it was fairly clear. Just after we entered the water we saw this huge Sea Cucumber (Thelenota ananas).  This species is also known as the Prickly Redfish or the Pineapple Fish. Of course, it’s not a fish at all, neither is it a pineapple. However, its species name, ananas,  does mean pineapple. Well, okay, a pineapple is actually Ananas comosus.

Bêche-de-mer


Believe it or not, people eat them. I guess people eat just about anything, but I have a problem with this one. Of course, there are many different species. None of them look tasty to me:Prickly Red Fish, indeed!

How prickly? Have a look at this. If you scaled this up to human size, we’d all be covered with 10 cm wide spiky star-shaped red warts:It’s pretty in a very bizarre way – definitely one of the more unusual skins that I’ve seen.

Here is the front end:Or is it the back end? Some Bêche-de-mer have easily discernible front and rear ends. I didn’t take time to give this one an anatomical exam. You can usually tell by the trail of sandy poo left behind. There was none here. Maybe it was constipated.

Keeping with my rare Christmasy mood, Here is a bit of green to go with our red. It is a particularly lovely Magnificent Anemone (Heteractis magnifica):The outside of the ‘jug’ is the underside of the anemone. They usually lie in the feeding position, which is spread out like a carpet. If the surge gets to be a bit much or it is not a good feeding time, the skin contracts and pulls up, often leaving only a few tentacles sticking out of a hole. Surprisingly, any anemonefish residing in the anemone will be popping in and out of the hole, much as you see here. By the way, the fish here is the Pink Anemonefish (Amphiprion perideraion).

Keeping in the spirit of “what you see is what I saw” here is an image of some Pickhandle Barracuda (Sphyraena jello)  coming up the side of the reef. Note all of the particulate matter floating in the water:It’s not all clear sailing.

Not forgetting my intent to bring you a Christmas Tree Worm every day until the 25th, here is your Spirobranchus giganteus  for today:Happy holidays!
