Do you like night dives?
Not long ago I asked a relatively new diver whether she was going to do a night dive that was part of a trip. Her response was: I’ve never done one will I see anything? My response was probably a bit snappy: yes assuming you turn on your torch and keep your eyes open. I went on to explain that since we were diving in the ocean and on a reef she would normally see the “night shift” of critters. Many of them would be hunting for their dinner while the creatures she had seen on the reef during the day might be hanging out in holes in the reef and trying to sleep all in hopes of not being eaten.
She asked who were the critters that we might see that we’re hunting for their dinner. I said if we were lucky we might find some octopus feeding.
She asked what else might she see. I said well we might see a nudibranch or two.
She asked will we see anything weird? I said well it depends on what you mean by weird but since we were in Southeast Asia I said well we might see a bobbit worm.
On that night dive we did see a bobbit worm which the dive guide would periodically push a morsel of food to. Our newer diver was startled the first time the jaws of the bobbit worm snapped shut and the worm pulled his prey into his hole in the sand.
When we eventually returned to the surface our newer diver said can we do that again? My response was well perhaps tomorrow. Will the boat need to save a space for you? The answer was: Of course…..
Have you been black water diving?
I had been diving for nearly 20 years before I ever came across black water diving. When I first heard that to do the dive we would be out in very deep water at night (perhaps over 1000 feet deep) with video lights on a string providing light to the creatures that might swim up for the depths, I had a few concerns. Sure I had done quite a few “shark” dives over the years, but I had always done those dives in the daylight so I could at least see them coming. I talked to the dive leader and heard that in all the black water dives they had done to that point they had not been visited by any sharks. Then I asked about what I might see in the night. I then heard about the great vertical migration. The short version is that billions of larval size creatures swim up from the depths each night to feed at the surface, only to return to the depths before daytime so they do not become some predator’s breakfast.
Like much in diving good buoyancy control was essential because unlike some places that do tethered black water dives we would be swimming fee without being tethered to the boat. Now controlling buoyancy plus controlling light for taking pictures sounded like quite a challenge. One of the tips I did hear and pay attention to was to listen to my ears. If I was having to clear that meant i was going deeper. So I thought that what I would do is have one eye on the string of lights and the pumpkin at the top, and have one eye focused on what was available to see.
My first black water dive, I swam around a ton and my focus light had a very wide beam. I thought I was swimming in a snow storm. The closest I got to getting a usable image was a picture of the ink from a squid that had jetted away from me.
Three years went by and I returned with the same camera rig except this time instead of a wide angle focus light I used one with a very narrow beam. Was it hard taking picture of the creatures I found on my second black water dive? In a word: yes. But I was more confident of what I would do and had a good bit more success in capturing some of the critters that had come up from the depths. Now buoyancy was still a big concern because even with having the string of lights as a reference point it would have been very easy to drop below the last light. What I can say is that black water diving is an advanced skill and if not tethered it is really a dive that should be saved until the diver has excellent buoyancy control skills.
Have you been diving in St. Martin?
Warm blue water with a ton of marine life to me is a great hook to go visit an island. In early July 2022 we sailed around St. Martin and got in a pedestrian 8 dives in a week. Nevertheless, we still saw a good variety of reef live. Some of my favorites were the turtles. All were green sea turtles but there were quite a few of them. Most were eating on the reef. Only one was swimming apparently looking for a meal.
But we also saw a variety of fish. Some were the usual pretty grunts that would show up in relatively large schools.
But the colors on the reef were not limited to browns and yellows. Instead there were also reds and other colors.
And of course, often on the edge of visibility there were grey reef sharks patrolling around the divers.

Do you like to see small critters?
I started doing blue water dives in the Caribbean almost 20 years ago. Clear water, a pretty good abundance of fish life and a number of species of shrimp, crabs and mollusks. Of the mollusks, sea slugs and other critters that had caught my eye, mostly did so because of their brilliant colors. Early on I did not spend much time searching for colorful critters. At least according to the critter books I have, it looked to me like there might be slightly more than a dozen nudibranch species in the Caribbean.
Overtime, it appeared to me that I needed to expand my horizons and see some of the sea life in the Pacific. After several trips to various parts of the Pacific, I stumbled on to muck diving in the Philippines.
Now mind you historically, my underwater shooting has been probably 90%/10% wide angle to macro images. So on my first trip to do muck diving, I was trying to get my mind around a very different kind of shooting plus get a sense of what the creatures might look like and how to capture them. When I got to the Philippines one of the comparasions that struck me was that unlike the Caribbean that has slightly more than a dozen different types of nudibranch for example, there were over a thousand different varieties of nudibranch.
I learned a lot on the first trip, not the least of which was to see the benefit of controlling the light through the use of a snoot. The snoot I took on the first trip to the Philippines I had picked up a few weeks before I left. Yes, it constricted the light from the strobe that I attached it to. But, aiming the snooted light was a real problem. The set up lacked an aiming light. Frankly, the snoot looked more like a funnel that you might find in your kitchen than a light shaping device. So it was largely hit or miss unless the guide I was with helped me aim the snoot. When shooting the light worked, it was really helpful at lighting the subject and not lighting a lot of the background.
Then I tried a snoot that had a focus light in it. For someone like me with relatively short arms, its still a challenge to get the snoot aimed well and then take pictures. Nevertheless having an aiming light did make it much easier to focus on everything else about capturing the image and worry less about getting the snoot aimed right.
So I guess you could say I’m hooked on controlling the light with a snoot.
Is it better than scraps?
Have you been to the “bad lands” in Belize?
Belize is about the size of Massachusetts, so we are not talking about a large land mass, at least for someone from Texas. Belize is lucky because off it’s coast is the second largest reef system in the world. The Meso American reef stretches the entire length of the coast of Belize and carries over to the Riviera Maya in Mexico to the north, and down to Honduras to the south.
There are quite a few islands off the coast of the mainland. Perhaps the most famous islands include San Pedro, and Caye Cauker. What becomes obvious if you fly into Placencia, is that there are quite a few islands not far from the mainland. Many of the islands and islets have interesting names such as Ray Caye, South Caye, Silk Caye ect. Some are have houses or other buildings on them. Some are not much more than a palm tree or two and maybe a mangrove tree or two. But sandwiched among a number of the islands is an area that from a sailing perspective is a fairly difficult area to navigate. In the “bad lands” the water tends to be shallow, and the reef is not particularly well charted.
Ten years ago when we first sailed into the bad lands with a very capable South African captain, he told me that he really watched his gps chart constantly because he did not want to run aground. He explained and it became pretty obvious fairly quickly that the reef was very shallow and rose and fell without a lot of warning. Our captain 10 years ago followed exactly the same track on each trip, just so he would not run aground. Ten years later we sailed with a Belizean captain. Captain David knew the bad lands like the back of his hand, but still he was careful to watch the shadows in the water to make sure the reef did not reach up and grab our boat.
But because the bad lands are pretty shallow they make an excellent place to go snorkeling.
Are the bad lands deep enough to dive, perhaps, but they are probably better just to snorkel and save our gas for a part of the reef that is not so shallow.
Have you been to Silk Caye?
Not long ago I visited Silke Caye which is south of Placencia in Belize. I had been to Silke Caye about a decade ago and when I dove there then the wind was howling and the water was pretty stirred up so underwater photography was a real challenge. This time Hurricane “Grace” had gone by to the north, but had still managed to stir up the water. Nevertheless, we still went diving. We had a warm day, but the trip out was basically windless and the water was glassy calm. We got out to Silke Caye and received the obligatory briefing from the park ranger about where you can go and where you can’t go within the park. After the briefing the snorkelers stayed on the island of silk caye to snorkel. Calling it an island is probably an exaggeration because it is so small it only has three palm trees and a single camp style toilet.
Meanwhile the divers got back in the boat and we motored out from the island maybe another couple hundred yards to a wall where we did our first dive. We back-rolled off the boat and started down. If you have been to Belize you are probably aware that the segment of the Meso American reef which runs by Belize tends to have a lot of soft corals which include sea fans and and sea whips. Yes, there are hard corals, but oftentimes they are surrounded by the soft corals.
One thing I noticed after a while was that there seemed to be a substantial decrease in the numbers of native fish stock on the dive. There were squirrel fish who were pretty well ensconced in the holes in the reef. But, what I did not see were the large numbers of grunts, snappers and other smaller reef fish such as blue chromis. We did find several lion fish which we speared . We also saw several nurse sharks one of who followed out group for much of the dive.
When we first came across the nurse shark, I thought well if we get one pass we will be pretty lucky. Well fortunately I was wrong. We would swim a ways and he would circle back to check us out. He tended to swim right through the group of divers. So I began dropping down to the level of the soft corals and positioned myself so he would swim right to me. In all he made maybe a dozen passes during the dive. Sometimes he would turn just as he got to my camera. A couple of times he swam under me.
So at least on the first couple of dives we saw a lot of nurse sharks and soft corals but not as many native species of fish.
