Heart of the Hunter – Part 2

Yesterday, I dumped a bunch of images on your screen that I’m preparing for an article for Niugini Blue  magazine. The title will be Heart of the Hunter. Look back at my post from yesterday to read all of my blather about that.

Today, we’ll just look at some of the rest of the images that I’m submitting.

You’ve seen the Spotted Shrimpgoby (Amblyeleotris guttata)  here before. I’ve even managed to get shots showing the commensal shrimp that lives in the same burrow. I spent about fifteen minutes sneaking up on this scene to get the fish along with two  of the  shrimps Alpheus ochrostriatus:

I could see that there were two shrimps living with the fish in the burrow, but it took a lot of patience to wait until both of them came out at once, pushing sand in front of them as if they were tiny bulldozers. The Spotted Shrimpgoby appeared previously here and here. If you get too close or make a sudden move, they all pop back in the hole in a flash.

Stalking relatively immobile critters is easier.  You’ve seen this nudibranch (Notodoris minor)  here before several times (put notodoris in the search box):

Nudibranch (Notodoris minor)In this shot, I think I’ve finally figured out how to get the subtle bumps and curves of the body of the beastie to show clearly. The thing is so bright and so monochromatic that you can’t really see this much detail with the naked eye. It’s an interesting example of how a photographic image can show you details that you can’t see with your eyes. Underwater, this critter looks pretty much like a blob of bright yellow with black stripes. It’s very hard to make out any detail.

I shot this image of the Spotted Porcelain Crab (Neopetrolisthes maculata)  a couple of years ago with my previous UW camera, an Olympus C8080:

Spotted Porcelain Crab (Neopetrolisthes maculata)As I said, there are too many variables to make a direct comparison, but it certainly looks as if I’ve lost nothing in the change.

This shot of a Spotted Garden Eel (Heteroconger hassi)  is one that I must admit makes me feel almost like a pro:

It’s not so much that it’s technically perfect – it isn’t. However, if you understand the behaviour of these eels, you will appreciate how difficult it is to get a good, clear close-up. The garden eel is usually found in mobs sticking up out of the sand. That’s all well and good – and quite pretty. However, when you approach them, they all pull back down into their holes; it’s their best defense. To get this close to one requires Job-like patience and a full tank of air. I cheated a little by easing a bit of telephoto into my lens, something which is normally useless underwater, since there is always too much stuff floating around.  I also had to do an enlargement trick (the multiple 110% enlargement method, in case you’re a Photoshop fan) to get the image big enough to crop out the middle and still have good detail. I’d guess that the front of my camera was about a half-metre from the eel.

Look, he’s winking at me.

Today was a Tsunami Day in Madang. It started out with a rather unremarkable sunrise. I staggered out to the water’s edge dragging my tripod behind me like a broken crutch and sat down to wait. This was as good as it got:

A Sunrise Panorama with glassy water (15 second exposure)

That shot was stitched together from three frames of fifteen-second exposures. The water is nicely flattened out and glassy. Too bad the sunrise itself was so flaccid. Otherwise, it might have been perfect. Story of our lives, eh?

We heard the tsunami warning on CNN. However, as usual, CNN was not aware of the existence of Papua New Guinea. Sometimes I imagine imaginary conversations in the CNN studio:

ANCHOR:  What’s this blobby looking thing here on top of . . . what is that, Austria?

CAMERAMAN:  Uh, no. That’s AustrALIA, not AustrIA.

ANCHOR:  Yeah, yeah, but what’s the blobby thing?

CAMERAMAN:  Dunno.

ANCHOR:  Let’s get rid of it.

Do you suppose that we would all disappear?

Anyway, when I got to work I had an email from Kyle Harris, our official science dude and tsunami watcher. He said that it was going to arrive at 11:25 or thereabouts. I looked at the clock and calculated just how much time I could waste writing in my journal before I needed to get into the truck and go over to Coronation Drive with my camera to see if I could get a cool shot of a giant wave curling over the top of my head. I got all excited just thinking about it.

At about 10:30 we got news that the warning had been cancelled. The tsunami was a little weak in the knees and got all tired out before it could get to us. This, of course, did not in any way affect the unrolling of a normal Tsunami Day in Madang. I heard that government offices and business were all closing. I suppose that there was a big traffic jam on Modolin Road as everybody at once decided to head for Nob Nob Mountain. I say, “I heard – I suppose” ,because I never left the office. I was still thinking about the incredible shots that I missed. Tsunami Days are getting to be like spur-of-the-moment holidays in Madang.

Hey, I’m not complaining. I’d rather see folks get a hundred days off for false alarms than see one poor schmuck get washed off the beach while pointing his camera straight up at the water. Especially if that schmuck is me!

So. How about some fish?

This is a Five-Bar Shrimpgoby, some species of Amblyeleotris,  I think. My reference book is a little vague on this one:

Five-Bar Shrimpgoby (Amblyeleotris sp.)

Here’s another individual under different lighting conditions on the same dive:Five-Bar Shrimpgoby (Amblyeleotris sp.)

These little guys have about 2,000 relatives that are also classed as Gobies. The family includes some of the smallest vertebrates on the planet – tiny adult fishes no bigger than the diameter of a pencil.

Spotted Shrimpgoby (Amblyeleotris guttata)

The one above is a Spotted Shrimpgoby (Amblyeleotris guttata).  They are not called Shrimpgobies because they are small, though small they are. They are usually partnered up with a small shrimp which lives in the same hole and keeps the house tidy by pushing all of the loose gravel out. The shrimp feeds on tidbits rejected by the goby and the Goby’s poo. Yes, poo. Little goes to waste in the ocean.

Now that I think of it, I have a shot from about five years ago of a Spotted Shrimpgoby with its little buddy (Alpheus ochrostriatus):

This is a kind of Sea Squirt (Polycarpa aurata)  that you’ve seen here before. When I see a nice one, I can’t pass it up. It looks like some kind of joke to me:

This character is a Pennant Bannerfish (Heniochus chrysostomus):

Pennant Bannerfish (Heniochus chrysostomus)It’s another of those pesky critters that stay just beyond the effective range of your camera. Pfffft! Psychic fish; who needs them? This is the best shot that I’ve managed yet of one of these snooty little creeps with the redundant name. Hey, a pennant is a banner, right? Okay, but it’s like  a banner.

Never mind.
