Turks and Caicos Explorer: Find the Reef Critter
ktuli — Mon, 12/03/2012 - 20:25
So if you've been following along, you'll know that I love finding the little stuff. On land, it is one thing... and I'm constantly looking for bugs and spiders. On the reef, it takes on an entirely new challenge. Like the search for the Gaudy Clown Crab, finding interesting and beautiful tiny little creatures while on a dive is something I take great pride in doing.
Normally I would post cropped photos with their originals available with a mouse-over action. Instead, for these, I'm going to post the original and let you see if you can spot the tiny little critter. If you're having a hard time, simply mouse-over the image for a cropped view that should help...
We'll start off with something easy...
Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM, 1/200th sec at f/16. Image Stabilization on. ISO 160. Ikelite Housing and Port with Ikelite 161 Strobe in TTL Mode. Raw conversion in Photoshop CS5.
Too easy? Ok - well, think about it this way. That shot was taken at 1:1.5 magnification. That means the frame is 1.3 inches x 0.9 inches. Looking at how much of the frame that Roughhead Triplefin (Enneanectes boehlkei) takes up, I'd estimate that it was only a mere 0.75 inches long. Sure - he stands out while sitting on top of that sponge, but still... that is a translucent bodied fish with some white markings (that mimic the white detritus stuck to the sponge) in a vast ocean.
Ok - this next one should be fairly easy too...

That shot is also at 1:1.5 magnification, which makes that little guy about 0.15 inches high if my math is right. It is either a Roughhead (note the fringes above its eyes in the zoomed version) Blenny (Acanthemblemaria aspera) or a Secretary Blenny (Acanthemblemaria maria) - I can't tell which without more visibility to the markings on the side of the fish. I posted another blenny from last year's trip as well for more examples of these tiny little fish.
Alright, that's enough of the easy ones. Now we'll take a look at where camouflage and tiny size come together to make for an truly difficult find...

That little guy is some sort of crab. I'm not able to find it in any of the identification books I have (not really surprising). Who knows - it could be a baby of some larger species of crab, or it could be that small all the time. Perhaps I found something no one else has ever seen before. All I know it is was tiny - probably in the range of 1/5th of an inch - and blended in perfectly with the sand.

That ridiculously tiny and cryptic thing appears to be some sort of shrimp or maybe even a lobster larvae. Once you see it, that dark stripe really stands out, but considering this was spotted just out on the sand, it really wasn't easy to spot.
Having said all that, don't ask how I spot these things - the answer is "I just do". I can't explain it, I can't tell you what specifically I look for - I just scan constantly and things jump out at me. A line that breaks a pattern (eyes are usually a dead giveaway), or a pattern itself in some camouflage, or a tiny bit of movement - regardless of what it is, my eyes are constantly searching when I'm on a dive. Searching for the next awesome little critter to zoom in on and reveal a view on something most people don't get to see.
When's my next dive trip scheduled???
