Great barracuda

This is a photo that comes with a story. There’s a place where I often snorkel that is home to a large group of barracudas. Most of these barracudas are around a foot and a half in length, though a few are much larger than that. I’ve mentioned before how barracudas give me the willies. They have not attacked anyone in Hawaiian waters to my knowledge, but they just have a certain look about them.

On this day I had passed the barracudas’ territory closer to the shore than I usually do. I didn’t see a single one of them. On my return, I swam farther out and, at one point, saw this barracuda and a second one (the jaw of which can just be seen in the photo) coming toward me. This was a bit unnerving but they slid by to one side, which is when I took this photo.

I turned my head and saw them curl around behind me. This wasn’t unusual; I’ve often had barracudas track me as I pass. Then I noticed a couple more arrive. This was less reassuring. I kept swimming steadily because I didn’t really have any other options. There was no way I was going to outrun them. Pretty much everything in the ocean moves faster than me and that probably includes some snails and sea cucumbers. Equally, I didn’t feel like turning to face them because the possible results of doing that included some I didn’t much like.

It seemed like every time I turned my head to see where they were, another barracuda had joined the pack. There must have been eight or nine of them at one point. Luckily, I didn’t see any of the very large barracudas among them, as that would definitely have made me even more nervous.

After a while I reached a rocky islet, a place where I usually first encounter the barracudas. They were all still behind me when I got there, but soon after I passed they were gone. While I’ve seen them in many different areas, this spot does seem to mark some edge to the territory of the main group.

I swam on, looking behind from time to time, and feeling more relaxed each time I did so. At least until I looked ahead one time and saw one of the huge barracudas heading right at me. It too passed by and I didn’t see it again, but it was time for me to get out of the water.

Lizardfish

Lizardfish are fairly small and hide by remaining motionless on rocks and coral, relying on their patterned colors to blend in. This works very well and I rarely see them, but I noticed this one in motion moments before it plopped down where you see it. I think this one is a reef lizardfish.

Threadfin jack juvenile

Threadfin Jack JuvenileThis week’s Friendly Friday challenge theme is ‘Fake.’ See more responses here. I don’t really have many photos that fit this bill, but this one does. This exotic-looking little fish is a juvenile threadfin jack. This is a fish that will grow up to become large and blocky, living in deep water and rarely seen by snorkelers of divers.

But as a juvenile, while still not often seen, it hangs around in shallow waters towing this extraordinary array of filaments. The theory is that the filaments make it look like a jellyfish and thus much less appetizing to predators. The fish will putter along, then throw in a few moves that make the filaments ripple. The first time I saw one doing this, I thought it was a jellyfish. It faked me out, which is exactly the point.

Usually, each year I see one, two, or even three of these juveniles in my local snorkeling bay, but this year I haven’t seen any or heard of them being spotted by anyone else. Not sure why this is. The water has tended to be murkier than is usual in the summer, but otherwise not much has changed. May and June is the usual time to see them, but I have seen them as late as September, so there’s still time. (This photo is taken from a previous year.)

I hope one or two do show up. Seeing them is one of the highlights of the snorkeling year for me.

Little fish in the surge

It’s common to see shoals of small fish, like those in the photo, close to shore in the surge area, where waves crash ashore. Swimming in groups gives these young fish their best chance of making it to adulthood, and staying near rocks in shallow water is another form of defense for them.

I find it amazing that even little fish like these will accelerate and change direction almost as one.

Longnose butterflyfish

The longnose butterflyfish gets its name for fairly obvious reasons, though it could equally be called the yellowsquare butterflyfish, blackspot butterflyfish or pailfin butterflyfish.

There are actually two different kinds of longnose butterflyfish. This one is the common longnose butterflyfish while there is also a big longnose butterflyfish, which is a little larger and has a slightly longer nose. The Hawaiian name for both these fish is lauwiliwili nukunuku ’oi’oi which, according to John Hoover in his book The Ultimate Guide to Hawaiian Reef Fishes, Sea Turtles, Dolphins, Whales, and Seals, is the longest of all Hawaiian fish names. In the Hawaiian name, lauwiliwili means ‘leaf of the wiliwili tree,’ nukunuku means ‘beak,’ and ’oi’oi means ‘best’ or ‘sharp.’

Bluefin trevally

A couple of bluefin trevallies seen while snorkeling in Kealakekua Bay. The area is a marine conservation district where fishing is prohibited. In general, I’ve found that fish in such districts are less skittish and more likely to approach snorkelers, so it’s a good place to get photos of some otherwise elusive fish.

Bluefin trevallies aren’t exactly elusive, but these two passed close by, unperturbed by my presence.

Great barracuda being cleaned

Great barracudas give me the willies, more so than sharks or most anything else in the ocean. There’s something about their appearance and how they hang motionless in the water that I find unnerving.

A little way south of my usual snorkeling spot, there’s a concentration of these fish that always rattles me as I swim through. Most of the barracudas I see are two feet long or less, but there a few among them that are much bigger than that. When I run into them, I’m leery about pointing my camera at them in case that upsets them in any way, because they don’t look like fish that would take kindly to being upset.

On this day, I was swimming with a friend when we came upon this very large great barracuda, just hanging in the water. Turned out it was being cleaned. The little blue and yellow fish above the head of the barracuda is a cleaner wrasse. These little fish set up store in different areas and clean mucus, dead tissue and parasites off other fish, which make regular visits to take advantage of this service.

Many fish being cleaned have an aura of great contentment while it’s going on, and this barracuda also looked quite relaxed, to such an extent that I lost my trepidation about it and got a bit closer than I normally would.

The wrasse is probably around 3 inches in length which would mean this barracuda is probably around 4 feet long.
