Here’s looking at you

Giant Porcupinefish

Giant Porcupinefish with Blackfin Chromis and Goldring surgeonfishI was swimming one day when I realized I was being watched. Peeking up from a crevasse in the reef, was this giant porcupinefish. These fish do seem to be quite curious and this is a look I’ve seen before. The difference here was that the water was quite shallow, so the fish was not as deep as they usually are. If I got too close, the fish would dip deeper into the crevasse. If I moved away, it would pop up again.

Porcupinefish are not to be messed with. They have strong beaks (fused teeth), which they use to break mollusc and crustacean shells, and which have been known to sever fingers, too. In addition, like pufferfish, they can inflate themselves with water into a large, round ball when threatened. Unlike pufferfish, porcupinefish have sharp spines which normally lie flat, but which become erect when inflated. Finally, they’re extremely poisonous.

The other fish, in the second photo, are a goldring surgeonfish and, above it, a small blackfin chromis.

Ironman 70.3

Going the other way at Ironman 70.3Approaching the turn at Ironman 70.3Last Saturday was the Ironman 70.3 race on the island. Unlike the Ironman world championship, held here in October, the 70.3 series covers half the distance. That means there’s a 1.2 mile swim, a 56 mile bike ride, and a 13.1 mile run. However, as with the longer race, Hawi is the turnaround point on the bike leg, so I ambled down to take a look.

Top: Racers heading in opposite directions shortly before/after the turnaround.
Middle: Slowing to make the turn.
Below: Bottles and trash can only be dropped in certain areas, where volunteers quickly pick them up for disposal or recycling.

I figure that if they’re doing a half distance race, it can’t be longer before they offer other shorter versions. I’m waiting until they get down to a one sixty-fourth Ironman and then I’m racing. Still a little worried about the run though.

I headed back to Pu’u Wa’awa’a last week, because this is the time of year when several kinds of trees are in bloom. One of those trees is the jacaranda, which blooms from April to June, and produces masses of blue to lavender flowers. Jacarandas prefer cooler elevations so the lower areas of Pu’u Wa’awa’a are right in their zone.

I wasn’t disappointed. Several trees were covered with these delicate flowers, which somewhat made up for the fact that the entire hill was shrouded in thick vog, exacerbated by the ongoing eruption down in Puna.

Smithsonian Submillimeter Array

I post this for two reasons. The first is that recently I had an exchange on this blog with the wife of the Director of the Submillimeter Array (SMA). The second is that Mauna Kea is a favorite place of mine to visit.

So here are a couple of photos of the SMA taken a few years back. The dishes are mounted on those little round pads in the photos, and they can be moved to different pads to produce different configurations. In my ignorance of most things scientific, I marvel at the idea of moving a dish a few meters makes a big difference in observations of things way the heck out there in space. That’s not an official measurement there.

The top photo shows seven of the eight dishes that make up the array.
The other photos, of three dishes and what immediately popped into my head when I saw them, show why I never made it as a scientist.

The eyes have it

Sheep with older lamb

Another response to the last edition of the WordPress photo challenge with a theme of ‘All time favorites.’

After a recent hike, I was returning to my truck and saw a small flock of sheep ahead on the track. These two caught my attention. The smaller one on the right was, I assume, the other’s lamb. Just before I took this photo, I saw it going for milk with that pneumatic drill approach that lambs have.

Before and after that, the ewe stood still, unwaveringly fixing me with those intense eyes. Then the two of them ran off to follow the rest of the flock that had already moved on.

There’s no doubt that moving to Hawaii has allowed me to gain an appreciation for creatures that live underwater. Where I lived before, in Washington State, getting in the water involved a huge amount of courage, which was rewarded by hypothermia and death 15 minutes later. I still consider it something of a minor miracle that I can jump in the water here, swim around for an hour, and emerge alive!

Photographing those underwater creatures is always something of a challenge. My camera is, essentially, a little point-and-shoot and I have no special lighting. The water is often murky and it’s always moving, I’m moving, the fish are moving. So I’m happy when I get a decent shot.

I spotted this devil scorpionfish when I was following a different fish and saw this unusual-looking ‘rock.’ It’s typical scorpionfish behavior. They have such good camouflage, that they can sit on the bottom in the open and not be noticed. After a few moments, the scorpionfish moved off and, as it did so, flashed the colorful undersides of its pectoral fins. This ‘flash’ serves as a warning to would-be predators that an encounter is not likely to end well for the attacker as the scorpionfish has venomous spines.

As for the other photo, I have it on good authority that his mother loves him.

Adult black-crowned night heron

I’ve run photos of black-crowned night herons a few times before, notably here and here. Both those posts could qualify as favorites, but they showed juvenile herons and one feature of the juveniles is that they don’t have a black crown.

These photos are of an adult bird and make it fairly obvious why they have their name. Another feature of this breeding adult is the long white head plume. And finally, all I can say about the bottom photo is, “I love what you’ve done with your hair.”
