Bluefin trevally and whitemouth moray eel hunting

A Bluefin Trevally and Whitemouth Moray Eel hunting in the waters off the Big Island of Hawaii

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.

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.

Abstracts: Floating branch

The last of this week’s posts in response to the WordPress photo challenge on the theme of ‘transient.’

High winds resulted in a bump in the amount of debris in the water. This branch could be on its way back to shore or headed for somewhere across the Pacific, depending on how wind and currents move it.

A pushmi-pullyu eel?

At first I thought this was something straight out of Doctor Dolittle, a pushmi-pullyu eel. Alas, no. Instead, it’s two whitemouth moray eels wedged into the same space behind a clump of coral. While whitemouth moray eels are a fairly common sight in the water, this is the first and only time I’ve seen two together. I don’t know whether this proximity was related to breeding. Perhaps they were just helping each other stay warm! Looks like they must be pretty good friends.

A manta ray glides by

Most weeks I post something in response to the WordPress photo challenge. This week’s theme is ‘evanescent,’ a word I wasn’t familiar with. The definition provided is “soon passing out of sight, memory, or existence; quickly fading or disappearing,” or, put simply, ‘a moment in time.’

To me, this is what any photo is, a snapshot of a given moment. Even the look of a fixed object, a landscape, a building, a monument, is always changing. It could be the light, weather, activity around the subject. Everything is in constant flux, sometimes in obvious ways, sometimes only in the detail. With birds, animals, bugs, even plants – blowing in the wind – those changes of passing moments are more obvious.

So I thought I’d take this week’s challenge as my theme for the week (or at least the remaining six days of the challenge). I start off with this photo of a manta ray. One of the great joys of snorkeling is never knowing what I’ll see that day. It could be a common fish engaged in some activity I’ve never seen before. It could be a glimpse of something unexpected. It could be something seen only at a certain time of year. Whatever it is, it almost always gives me a little jolt of ‘wow.’

While out snorkeling, I got a jolt of ‘wow’ when I saw this manta ray gliding along in the opposite direction. I turned and followed its effortless progress for several minutes until it headed into deeper water and disappeared. An evanescent experience? I think so, though it won’t soon disappear from my memory.

Coastal manta ray

Not the greatest photo – swell had churned up the water – but I post it for two reasons.

One is, it’s the first manta ray I’ve seen outside of a tour where they set up lights and an unruly mob of people hung onto floats while the manta’s fed off plankton attracted by the lights. The manta’s were fabulous; the rest of the experience was weird, bordering on unpleasant. To top it off, I didn’t get any photos.

The second reason is how I came to spot this manta in the first place. A group of three women was swimming about 100 feet ahead of me. They had masks and snorkels but not fins. I happened to pop my head above water and heard a scream from one of the women, followed by a huge froth of whitewater in their vicinity. They’d obviously seen something dramatic and my first response was to find out what it was, never mind that a scream and churning water might be a strong indicator of a shark attack.

As I swam forward, this great creature came into view, angling across my path. At first it wasn’t clear what it was, but then the two distinctive cephalic flaps became clear. Manta’s use these to funnel water into their mouths when feeding. Manta’s are plankton feeders and harmless. Many rays have stingers in the tail area, but manta’s don’t. John Hoover says an 8 to 12 foot wingspan is most common for manta’s in these waters and this one certainly fell in that range.

With little effort, it glided past me toward deeper water. As it did so I saw a second manta join the first, then they disappeared into the murk.

A few minutes later I talked to one of the women who’d been in the group ahead. She said she’d screamed because she was startled by the sudden, unexpected appearance of this huge creature. I sympathized. I’ve had a similar response when unexpectedly meeting sharks and eagle rays at close quarters. But at the same time, such chance encounters are magical and memorable and I am grateful for them.

In my attempts to identify what I see in the water, I use John P. Hoover’s book The Ultimate Guide to Hawaiian Reef Fishes, Sea Turtles, Dolphins, Whales, and Seals. His website is hawaiisfishes.com.
