This longnose butterflyfish was cruising around, probing for tasty morsels, when it disturbed this surgeonfish. I think it might be a Thompson’s surgeonfish, but it disappeared before I could make a positive ID.
Nearing the end of a long swim, I noticed these two fish swimming towards me. At first I thought they might be bluefin trevallies, but I could see the coloration was wrong. The other thing I noticed is that the two fish never deviated in their course, which took them right by me. Most fish, when they see someone coming their way, will zip away or at least cautiously ease around the interloper. Because they passed so close to me, I was caught by surprise and only managed to get these two shots before they were gone.
The fish are greater amberjacks, which spend most of their time in deeper waters, but occasionally venture in shallower waters as these two did. The fish are easily identified by the dark diagonal bar through the eye and the yellow stripe along the sides, though that isn’t always visible.
My wife spotted this crab scuttling quite rapidly along the floor of the bay where we were snorkeling. It was clearly some kind of hermit crab, but it was quite deep and this was the best photo I got.
When we got home, I looked through my copy of John P. Hoover’s Hawaii Sea Creatures and the jeweled anemone crab seemed the most likely identity. As can be seen in the photo, the shell is covered with anemones which is a feature of these crabs. Since these crabs are mostly night feeders, we were lucky to see one still active in the early morning. Possibly it had been disturbed and was headed to a new hiding place.
These little fish were swimming back and forth in the golden pools of Keawaiki. The gold color comes from a kind of algae that grows in the pools.
Last February, I posted about a new monk seal pup being born on the island (here and here). I’m happy to report that the pup, Manu’iwa, continues to do well. Now, her mother, RA20, has returned to the same site and given birth to a new pup.
The new pup is just over two weeks old and so far the signs are good. The pup is nursing well and the mother is being very careful around it. When Manu’iwa showed up to see her new sibling, the day after it was born, RA20 quickly put a stop to the meeting. Monk seal mothers are very protective of their pups.
Mother and pup will likely spend about six weeks in the area before RA20 leaves the pup to fend for itself. During that time, she will lose weight while the pup gains and they will be a lot closer in size than they area currently.
These photos were taken in the early afternoon when the pair were resting and not much was going on. Morning is the best time to see them being active.
These three were swimming together, the two goatfish probing for prey and the saddle wrasse hanging about to snaffle up tasty tidbits stirred up by the two other fish.
This little lemon-yellow beauty is a juvenile Commerson’s frogfish. Frogfish are rarely seen by snorkelers because they blend in so beautifully. Typically they look like bits of the reef but some, such as this one, mimic sponges and so are more easily seen.
Frogfish are anglers. They sit motionless on the bottom. When potential prey approaches, they flick their first dorsal fin forward. This is tipped with a fleshy lure that hangs over its mouth. If the prey takes the bait, the frogfish strikes. It can expand its mouth to swallow quite large fish and it strikes with such speed that other fish in the vicinity are generally unaware what’s happened, thus allowing the frogfish to remain in place and continue fishing.
In this photo, the frogfish’s eyes and mouth are visible, as are its pectoral fins that are adapted to help it hang on to the reef and to move about.
This frogfish was spotted by my wife and we watched it for a while before we were interrupted by three whales breaching. They were half-a-mile or more away, but this was the first time I’d seen whale activity from the water and it was pretty impressive, if almost impossible to photograph.
When the whales settled down, I dipped my head below the water to try and locate the frogfish again and the first thing I saw was a white-tipped reef shark cruising by. I suspect it had been attracted by my feeble attempts to dive and photograph the frogfish, probably thinking there was some easy prey to be had. It quickly disappeared again, but it made for a memorable few minutes.
A lone patch of coral stands out on the sandy ocean floor. Such areas tend to have less fish, presumably because they are more exposed. On the plus side, anything that is swimming in such areas is easier to spot.
