Coast Guard buoy ship

The Coast Guard paid another visit to Kawaihae recently, checking out the buoys marking the entrance to the harbor. The ship approached the harbor around the same time as a double-hulled canoe. The canoeists wisely decided to give the ship priority.

There are rules for who has the right of way on the water, but it’s always wise to remember that a large ship might have little room for maneuver, especially close to shore. I always bear in mind the epitaph, possibly apocryphal, which reads, ‘Here lies the body of Roger Wray, who died asserting his right of way.’

More manta rays

My most recent manta ray encounter happened a few days ago. I was swimming along and saw a familiar shape in front of me. It was a manta ray heading in the same direction. I tracked it for a while, hoping to catch up, but knowing that doing so was entirely up to the manta. Eventually I did draw level for a short while. Then the manta pulled away again.

As it disappeared, I thought at first I was seeing some kind of weird reflection in the water. Then I realized it was a second manta swimming toward me. As it approached the first manta turned and followed behind. Both were pretty large and up near the water’s surface, creating reflections.

They passed by, and receded in the direction I’d come from. I hung around for a while hoping they’d reverse course again and, sure enough, a few moments later the two of them came back toward me. On this pass, I could see that one had a badly damaged cephalic flap. It looked like an old wound and didn’t seem to trouble the manta much, but I don’t know how it would affect it when it came to feeding since they use the flaps to funnel plankton into their mouths.

Eventually, the mantas headed away and out into deeper water. I stayed out for a while on the off chance that they’d return, but wasn’t surprised when they didn’t. Still, it had been another wonderful encounter and I headed back toward shore in a very good mood.

Abstracts: Devil scorpionfish

I had just jumped in the water and submerged my head when I saw something move. The fish immediately plopped down by a rock but I’d already recognized the distinctive shape of a devil scorpionfish. I hung around for a short while hoping it would spread its pectoral fins in its distinctive display, but it never did. The second photo, which has run on the blog before, shows what I was looking for.

Giant trevally

A couple of days ago, I was snorkeling when I saw this enormous fish. I snapped a quick photo, fearful that the fish would quickly disappear. But it stuck around for a minute or two, passing back and forth in front of me, before sliding away into deeper water.

I knew it was a jack, but not one I’d seen before. When I got home, I dove into my fish book and figured out this was a giant trevally. According to my fish book, the giant trevally is the largest of the jack family. The biggest recorded catch is one that weighed 191 pounds. That would be heavier than me! That’s a tad worrisome because my fish book also notes that these curious and fearless fish ‘have been known to grab and rip away divers’ bright snorkel tips and colorful fins.’

This one was smaller than that, probably somewhere between three and four feet long, but comfortably the largest jack I’ve ever seen and probably the largest fish I’ve seen of any kind other than rays and sharks.
