Magnificent manta rays

Two manta rays in the waters off Hawaii

Yesterday, my wife and I hadn’t been in the water long when we saw large shapes ahead. There were two manta rays in fairly shallow water that was a bit churned up and cloudy. I took photos, but wasn’t optimistic they’d turn out in the conditions. The mantas swam away and we followed at a distance. There’s no point chasing mantas. Like most things in the water, they can put on a burst of speed that would leave us far behind.

The mantas didn’t go far before they curled around and came back towards us. The water was clearer in this area and sunlight illuminated them as they headed our way. The lead manta was quite a bit bigger than the other one, probably around a 14-foot wingspan. They passed close beneath us, then turned again, looped around and headed back. They did this back and forth three times before finally moving on.

Later, when I was coming back, I saw the big manta again. It was in deeper water that was more cloudy so I didn’t get photos, but I watched as it did a couple of loop de loops and some sharp banking and turning. It just seemed to be having a fun day in the ocean and in doing so, made it a fun day for us, too.

I saw this ship off the coast of North Kohala, but couldn’t immediately identify it because it was too far offshore. Luckily, it hung around and a couple of days later I saw it much closer and stopped to take photos.

The ship is the Nautilus and it’s an exploration vessel operated by the Ocean Exploration Trust and was engaged in research, sponsored by the National Geographic Society. They were studying marine mammal vocalization and local shark diversity and abundance around Hawaii.

Walking with dolphins

Wait a minute, I hear you say, isn’t that supposed to be swimming with dolphins? Usually yes, but in this case, I was walking along the coast when I noticed a splash in the water. Another followed and I quickly recognized the familiar shape and behavior of Spinner Dolphins.

For almost half an hour, I watched as a large pod of dolphins – at least 50 and possibly as many as 100 – cavorted offshore. We were all heading in the same direction and, in normal circumstances, dolphins would easily outpace me, but these were having fun. In addition to spinning, I saw a lot of other regular jumps. Sometimes the dolphins turned back the way they came or headed toward shore, surfing in the waves.

When I turned inland, to head back to my car, they were still in sight and still spinning and frolicking in the waves.

Spot the Scorpionfish

When I get to the end of a swim, I keep looking around because, as the water shallows, it’s possible to see a wide variety of fish and marine invertebrates.

Recently, I was about 10 feet from my exit point when I saw the Devil Scorpionfish in the photos. That’s right, there’s a fish in the top photo and it’s not the Bright-eye Damselfish on the left. The second photo gives a better view, where the fins stand out a bit and a flash of orange can just be seen on the left pectoral fin. A Devil Scorpionfish will flash these orange fins, probably as a warning to predators, since it has venomous spines.

Don’t feel bad if you can’t find the fish in the top photo. I wouldn’t have spotted it if it had been stationary, but in the shallow water, I noticed a small movement and quickly realized what I was looking at. I’ve seen a Devil Scorpionfish in this area before so this might be the territory of this same fish.

I’d just got in the water recently when I saw this Whitemouth Moray Eel hunting with some Bluefin Trevallies. The trevallies carried on, but the eel was torn between joining them and retreating into the crack it was emerging from. In the end it did neither and I got a few photos before carrying on with my swim.
