Cleaner wrasses establish territories where they remove mucus, parasites, and dead tissue from other fish. These cleaning stations can exist in the same place for years and can have several wrasses performing those services. Their clients can be anything from other small reef fish to eels and sharks.
In these photos, a Hawaiian Cleaner Wrasse services a Whitebar Surgeonfish.
A couple of creatures in the water that are like to blend into the background. The Titan Scorpionfish is fairly easy to spot in this one, but the Whitemouth Moray Eel is a bit trickier.
I like to keep an eye out for Collector Urchins to see what bits and pieces they have found to attach to their spines (here). What caught my eye with this one is that the shell on its back is that of a Yellow Cone. They do attach shells so I expect this was one of those rather than a living cone.
These are a couple of fish that spend a good deal of their time sitting, stationary, on coral or rocks. The similarity ends there.
The hawkfish is a predator, waiting for small fish or crustaceans to come within range. The blenny feeds solely on living coral. And while this blenny is probably an adult at about 6 inches long, the hawkfish can grow to twice that size.
On a recent swim, the most notable sighting was this duck, bobbing serenely in the water. It took a while to realize that its calm demeanor owed nothing to its personality, but all to its construction. The duck was a decoy, and a well made one, I thought. A dip under the water revealed no legs, but a good amount of marine growth, indicating it had been bobbing along for some time.
Yesterday, when I went swimming, the swells rolling in were larger than expected, and the visibility in the water, worse than expected. Consequently, it wasn’t a banner swim until I popped my head out of the water and saw spinner dolphins heading my way.
I reckoned there were at least 60 or 70 dolphins in the pod, but I suspect there the number was closer to 100. I count more than 25 in the top photo and that was one group going by on one side. The traffic was continuous on both sides, and below, for several minutes.
The dolphins weren’t hanging around, but zipped by, heading for their daytime resting spot. Several minutes later, a much smaller group passed by, traveling at a more sedate speed. I’m not sure why that was. Sometimes it’s because they’re escorting calves, but I didn’t see any. Perhaps they were just tired and not inclined to get caught up in the rush of the main group.
For some reason, on many recent swims I’ve seen a variety of cones in the water. Cones are marine snails and many have a venomous sting, which can be dangerous to humans, though not likely fatal.
The Hebrew Cone gets its name from its distinctive markings, which supposedly bear something of a resemblance to Hebrew letters. It’s quite common here, though this was the first one I’ve seen. Apparently, the largest Hebrew Cones are found in Hawaii, though that only means a length of around 2.5 inches, which this one might have been close to.
I saw this Flowery Flounder in shallow water and was able to get close enough to get this close up of the fish’s head. The bumps are the eyes.
The blue markings of the fish and the rainbow in the water made for a colorful photo.
