Bluespine unicornfish

Bluespine Unicornfish

On any given day, I’d rather be snorkeling. There’s always something interesting to see in the water here.

This fish is a bluespine unicornfish, a name which is pretty self-explanatory. The blue spines by the base of the tail are very visible as is the prominent horn. Not all unicornfish have horns.

The horn helps make the bluespine unicornfish look permanently grumpy, which is perhaps why these fish tend to lead solitary lives. They also tend to be wary around snorkelers, maintaining their distance or easing away when approached. This one, however, appeared more curious and made a couple of closer passes before disappearing.

Resting shark

While out snorkeling one day I came across this scene. It’s not a great photo (though the murkiness adds a little to the menace, I think), but still enough to identify it as a shark, resting on the sandy bottom. Later in the day, it was still there. It was more visible with its head out from under the ledge, but the water was cloudier so I didn’t take photos.

I’m pretty sure this is a whitetip reef shark as I’ve heard about one hanging out in that area. The white tips, that give the shark its name, are on the dorsal and tail fins so aren’t visible in this image.

Touching octopuses

For Valentine’s Day I offer this photo of two day octopuses. It comes with a little story.

One day, while I was snorkeling, I noticed a stocky hawkfish about to plop onto a bit of coral. Before it could settle, a blue goatfish butted it away, getting my attention. I wondered if its presence might mean there was an eel or octopus around since they sometimes hunt together. Almost immediately, just beyond the goatfish, I noticed a day octopus glued to the side of a rock.

I took a couple of photos but knew they wouldn’t be very good; the octopus just looked like another lump of rock. So I began the usual dance I do with an octopus. I edge away, as though I’m leaving, keeping an eye on the octopus out of the corner of my eye. I know the octopus is watching me. Often, when I’ve gone a ways, the octopus will rise up onto whatever rock it’s hiding behind. If I’m quick, I can turn and get a photo before the octopus slides back down again. It’s like we’re connected by a line: I go away, the octopus rises. I return, the octopus sinks.

I swam behind a large chunk of rock, then peeked around the side. Still there, still hidden. A bit farther, another peek. Still there, still hidden. And again. And then I looked away momentarily and when I looked back, the octopus was gone. I think they, like many other creatures, watch a person’s eyes and if the person looks away, off they shoot.

It was a matter of a moment so I knew it couldn’t have gone far. I looked around, examining the rocks. Nothing. They can squeeze into tiny spaces so it was always possible I wouldn’t see it even if it was close by. Then, as I turned around, I caught a glimpse of movement and saw the octopus zip behind a bit of rock. Except then I immediately saw a second octopus follow the first.

I swam around the rock and saw the two of them, each in its own separate crack, a few feet apart. Again I took a couple of photos and then moved away. This time I went farther and waited, watching from a fair distance. Eventually, the octopus on the right of the photo emerged and moved toward the other one. I edged closer and began taking photos. It was then that that octopus slowly eased a tentacle toward the other one, sliding over the rock until it reached up and over the front of the other octopus. It was such a sweet and tender gesture, as though the octopus sought reassurance in making physical contact with its companion.

I took the photo and swam off, leaving them in peace.

Fish feeding

Another post based on the theme of this week’s WordPress Photo Challenge, which is ‘Silence.’

It’s not unusual to see fish feeding while snorkeling, but on this day the numbers doing so, up near the surface, were large. These are mostly Hawaiian sergeants and black triggerfish, with a few indo-pacific sergeants amongst them.

By easing myself slowly toward them, they weren’t unduly concerned, parting as I got close and returning as I passed. I felt like I was swimming in an aquarium, a quiet environment without the usual noises of everyday life.

Divers down

Not surprisingly, Hawaii is popular with divers. Warm, clear waters and lots of fish and coral means there’s lots to see. For snorkelers, like me, the divers themselves are something to watch for.

I saw this group heading out toward deeper waters and liked how the light caught the bubbles of air, and also the colorful fins of two of the divers.

Bluefin trevally and whitemouth moray eel hunting

There are a fair number of predatory fish in Hawaii, that eat other, smaller fish. These fish have a variety of hunting strategies, everything from ambush to outpacing their prey. Some fish team up with other predators.

Fish that employ this latter strategy include various goatfish and bluefin trevallies. These fish often accompany each other on hunts, but either or both can also be seen with other predators including eels and octopuses.

I followed this bluefin trevally and whitemouth moray eel for a few minutes and didn’t see them catch anything, but they were definitely traveling together. If the eel hung out for a while under a ledge, as they like to do, the trevally would hang around, passing back and forth or circling the spot.

This tendency is actually helpful for spotting eels and particularly octopuses. Several times I’ve seen a goatfish or two milling around a rock for no apparent reason, so I’ve waited and watched. Sure enough an eel pops its head out or, better still, the rock turns out, on careful examination, to be mostly octopus.

There you go, an actual useful tip for snorkelers.

A giant porcupinefish peeking

This would have been a good photo for a recent WordPress challenge, peek, but I took this after that was over. However, it also works for this week’s challenge of ‘experimental.’

My underwater photography setup is not a spiffy camera and a bank of lights, but a point-and-shoot Canon S 90 in a waterproof housing. It doesn’t have tremendous zoom capabilities so I’m constantly experimenting with ways to approach fish so I can get a decent close photo.

Taking photos in areas where fishing, spearfishing, and fish collection are banned makes things easier. Fish in those areas seem to know they have less to worry about, at least from humans, so they’re less inclined to dart off. Elsewhere it’s a different story. Often I can get reasonably close, but when I raise my camera toward them they tend to zip away, possibly thinking it’s a new type of spear gun.

The best approach I’ve found is to be as quiet as possible in the water and just drift toward something I want to photograph. In this instance, I was puttering around when I saw this giant porcupinefish headed my way. I like these fish with their big eyes and a body tapering from the huge head back toward the delicate tailfin.

This fish spotted me and dipped down behind a large lump of rock and coral. I waited, but it didn’t reappear. I eased forward, keeping the rock between me and the fish. Still no sign of my quarry, so I slid to one side and saw the tailfin fluttering. Ah ha! With my camera ready and a gentle flip of my flippers I moved to the other side where I found the fish peeking out and giving me this look. I snapped a photo and an instant later the porcupinefish pivoted and headed the other way at speed.

Despite their ungainly appearance, giant porcupinefish are good swimmers and it was soon a good distance away, but when I got home I was happy to find that I’d got this shot. I also like how the goldring surgeonfish in the photo looks suitably startled by the whole encounter.

Hawksbill turtle

Returning from a long swim, I spotted this turtle cruising along beneath me. I turned to follow it, usually the cue for a turtle to glide away, leaving me in its wake. But this one circled around and went back and forth in the same area for a while.

At first I assumed it was a green turtle, which are most commonly seen around here, but I realized that this one looked a bit different. The bill seemed more pointed and the edge of its shell was serrated. I thought it might be a hawksbill turtle, which are seldom seen here.

When I got home and checked my book it confirmed that the turtle was a hawksbill, which is the first I’ve seen.
