First Dive of the Day...

...Second Dive of the Day!

Life (and diving) is good in Hawai'i!

Here's a few photos of a Devil Scorpionfish I saw on a recent dive. These fish are a miracle of adaptation having developed camouflage that allows them to blend in perfectly with a coral rubble bottom. They are ambush predators that wait patiently for a careless fish to swim by. The scorpionfish then quickly opens its mouth which creates a partial vacuum and sucks in the fish.

Scorpionfish have venomous spines in their dorsal, anal and pelvic fins. Stepping on one will result in a painful sting. Although this fish blends in with its surroundings, when disturbed it will swim a few feet and, in the process, reveals bright orange and yellow markings on its pectoral fins which advertise its presence.

While this fish is considered unattractive by many, it is truly a underwater wonder and is a treat to see on a dive!

Turtle Portraits

I got a new camera recently and am still having trouble getting the "feel" for it. What I'm learning is that it is pretty poor at focusing on anything that happens to be moving! Not a good thing for underwater photography. Anyway, to get some decent photos, I've been going to the turtle beds early in the morning to get some close-ups of the honu while they're still being still. I've gotten a few good results, these being the best.

Hawaiian International Billfish Tournament

This week is the annual Hawaiian International Billfish Tournament where teams from around the world compete to catch big fish. After school/work Jacques and I went down into Kailua to see the weigh-in. Only one fish was brought to the pier, this 531 pound marlin which was caught by a group of fishermen from Japan.

I myself am not into fishing but it is a big part of life here on the Big Island. A popular bumper sticker proclaims "Kona. A quaint little drinking town with a fishing problem". No matter how you feel about the sport, seeing a giant fish like this is a memorable event.

Redstripe Pipefish

These are a couple of photos that, while of debatable artistic merit, I'm happy to have taken. While pipefish are not terribly uncommon in Hawai'i, they inhabit environments that (for me, at least) are among the least hospitable for camera-wielding SCUBA divers. These photos were taken in a tight, surge-swept lava tube near the shoreline. The surge in and out of this tube was so great that I had to brace myself against the walls with both legs and one arm while shooting with my free hand. To make matters more challenging, bubbles from my regulator dislodged silt from overhead making vis poor and causing backscatter in the photos. Also, pipefish get nervous easily and swim kind of erratically when photographed.

Pipefish are classified as tube-mouthed fishes and are closely related to the seahorse. Like the seahorse, it is the male pipefish that carries the eggs until they hatch. They are quite small and easy to miss. This one was around three or four inches long.
