This week’s Friendly Friday challenge theme is ‘Morning Rituals.’ See more responses here.
Most mornings, I try to get in the water, as conditions and schedules allow. Morning is the best time for snorkeling as the water is usually calmer before the wind picks up as the day wears on. Visibility can vary from day to day and it can help to check surf reports to see if there are any swells moving in. But calm water doesn’t guarantee good visibility just as swells don’t always mean bad visibility. There’s only one way to be sure and that’s to jump in.
My favorite thing about snorkeling is that every day is different and I never know what I’ll see. Going to the same spot means I become familiar with some of the regulars, but there are always transient creatures passing through including rays and dolphins. And while those big creatures are great to encounter, it’s equally interesting to watch the activities of smaller fish and marine invertebrates.
It’s a rare day indeed that I don’t emerge prattling on about something I saw while I was in the water. And on those rare days, well, I’ve still had a good swim to set me up for the day ahead.
I get the impression that, for most people, if they have to see a shark, they’d prefer it to be from this perspective – going away from them. Being something of a contrarian, I’m always looking for sharks coming toward me. The qualifier in this is what kind of shark it is.
This is a whitetip reef shark, the first I’ve seen in quite a while. Whitetip reef sharks tend to be curious and will cruise up and check me out. Once they determine that I’m really quite boring, they carry on in search of something more interesting.
Now if this had been a tiger shark, well, all bets are off.

I’ve seen sharks when I go snorkeling, but this was the only time I’ve seen a shark from shore. I couldn’t identify it from just the fin and tip of the tail, except to rule out whitetip and blacktip reef sharks. Likely candidates would include gray, tiger, hammerhead, and Galapagos sharks.

This week’s Sunday Stills challenge theme is ‘Something Scary.’ See more responses here.
Here’s a photo of a whitetip reef shark passing almost directly beneath me. In truth, these sharks aren’t especially scary since they’re more curious than dangerous, but the sinuous movement and serious chompers can send a shiver through anyone who encounters them in the water.
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.
These are older photos, but still interesting to me. I spotted this monk seal one day, not too far from a second seal that is a regular around the Big Island.
The top photo shows some lighter marking on the side of the seal, below and behind the two dark marks. This lighter marking is bleaching, which is applied to seals when possible, to help researchers monitor the population and keep track of their travels. The bleaching only lasts a year as seals molt annually. In addition to the bleaching, most seals have red tags placed in their rear flippers, to help identify them. It can be a hit and miss method as these photos show. This seal has tags in both flippers, but they were never visible to me.
The other interesting thing is those two dark circles on the seal’s back. They’re made by cookiecutter sharks. Cookiecutter sharks are small dogfish sharks, less than two feet in length. They feed by gouging round plugs, hence the name, out of larger creatures such as monk seals.
Cookiecutter sharks live in the deep ocean during the day, sometimes at depths over two miles. At dusk they rise up toward the surface, before descending to the depths again around daybreak. Another reason not to go swimming at night.
A couple of weeks ago I ran a post about my first shark encounter for about two years. Then, like buses, another one came along within three weeks.
The latest was another whitetip reef shark, which are the sharks most commonly seen around here. I was swimming in shallow water, when the shark popped into view over the edge of a drop off to deeper water. It was quite close and moving fairly quickly, so I snapped this photo as it zipped by, before disappearing on the other side of me.
The photo isn’t the greatest, but I post it for two reasons. The first is that it shows the black spots on the side of the shark. These are a way of identifying individuals because the spot patterns are unique to each whitetip reef shark.
The second reason is that I usually have my camera zoomed in (it’s not a high-powered zoom) so that I’m more likely to get a quick shot of a small fish before it disappears. This photo is zoomed in, but when I first saw the shark, my immediate thought was, ‘I’m going to have to zoom out for this.’ In the photo, the shark is probably around 10 feet away. Compared to the shark in my previous post, the details of this one, such as the gills, are much more pronounced though this shark was smaller, probably about 3-feet long.
Whitetip reef sharks are not considered much of a threat to humans, though they are curious and, as this one did, will come close to take a look. When people do get bitten by whitetips, it’s usually spear fishers towing their haul, or someone provoking the shark, possibly entrants in the worldwide ‘My Dumb Selfie’ competition that so many people seem so keen to enter.
I went for a snorkel a few days ago and saw a shark for the first time in a long while. Well, I did see one a couple of months ago at Two Step, but it was tucked into a small cave, having a nap. The recent one definitely wasn’t at rest.
I was fairly far out, near where rock and coral gives way to sand, and happened to be looking out towards the sand when the distinctive shape of a shark came zipping into view. It was headed my way at speed, which was an invigorating moment, I can tell you. However, I did have the presence of mind to snap a few photos, of which this is the best. Considering the state of the water and the shark gliding across the bottom, I was pleased with how well this turned out. I think it shows the infamous lines of the shark and something of its powerful, sinuous motion and I was glad to capture the eye and lines of the gills.
I suspect it had detected my presence and was checking me out. When it saw what I was, it decided I wasn’t too interesting, cruised by, and then disappeared in the opposite direction. I headed back in, taking frequent glances behind me to make sure the shark hadn’t changed its mind.
A couple of weeks ago, a couple of paddle-boarders were attacked by a tiger shark near Hualali Resort. Tigers sharks are responsible for almost all the shark attacks that happen around Hawaii. The shark I saw was a whitetip reef shark (notice the white tip on the dorsal fin – many have white edging on other fins, too), which is capable of mischief, but mostly doesn’t. This one was around 5 feet long, maybe a bit more. For scale, the yellow tang at bottom right of the photo is probably between 6 and 8 inches long.
