Sharks on Nearly Every Dive


The best moment of my recent dive trip to the Turks and Caicos Islands was something I  had to be told about later. As I was getting nose to nose with a big lobster to get an intimate portrait, a five-foot Caribbean reef shark passed behind me, circled around and was glancing over my shoulder as I snapped away at the lobster. When I finally turned around I caught a glimpse of the shark swimming away from me, and I couldn't get a picture. I wish someone had gotten a picture of the shark looking over my shoulder, but I have an image in my mind that's as vivid as if I'd seen it for real.

Underwater photography is like that. Actually diving is like that. Many are the times I've seen barracuda and turtles and sharks shadowing another diver who never knew it was there. 

We learn about these incidents back on the boat in the chaotic "debriefing" that divers conduct among themselves as they shuck their gear and peel off their wetsuits: "Did you see that hammerhead...?" "Man, that barracuda was checking you out..." "I have never seen so many Christmas tree worms in one place...." "Huh? I didn't see anything, worst dive I've ever been on..."
All you can do is shrug your shoulders and hope for better luck next time. A couple of years ago, I came up with a stock answer when I was asked if I'd seen "the shark" on the last dive. "Almost saw it," I replied. "Very close, but, no, I didn't see it."

For my fellow divers on the Turks and Caicos trip, the biggest thrill was one I knew about but didn't participate in. We had all gotten back on the boat after the fourth dive of the day and were organizing our gear when someone spotted a manta ray near the boat. Soon another one appeared, and the crew announced that the pool was open for anyone who wanted to snorkel with the mantas.

Almost everyone jumped in. I opted not to. I've got a host of reasons, none of which matter, but not least of which was I didn't think they'd stick around for long. As it turned out a third manta showed up, and the trio swam and barrel rolled around the boat for more than an hour as most of the divers followed and managed not to spook the rays. One of the crew, Lynn Greene, got a beautiful video sequence that you just have to see.

The mantas were the talk of the trip for the rest of the week, and I will admit I wished I'd gotten in with them, but it was still one of the best dive trips I've had anywhere, and certainly the best I've experienced in the Caribbean.

And sharks were the main reason.

I may not have gotten that one shark, but I did see reef sharks on most of the 23 dives I did over six days, and I was able to get pretty good photos of several of them. Any dive where you see sharks is a good dive. The only places I've seen more sharks are the Galapagos and Palau in the Pacific (I'm not counting shark feeding dives, where sharks are lured into unnatural feeding behavior for the amusement of divers, a questionable practice at best).

Much of the reef around Turks and Caicos is a marine park where fishing is prohibited. Such marine protected areas have proven to be valuable for the recovery of heavily pressured fish like grouper and sharks, which then re-populate nearby areas where fishing is permitted. That value is obvious in Turks and Caicos waters. Sharks are not the only beneficiaries. We also saw fairly good numbers of large groupers, eagle rays, turtles, barracuda and lobster, and then there were those mantas, of course.

And I was pleased to see fewer specimens of one other species.

Besides humans, the greatest threat to Caribbean reefs is the rapid spread of invasive lionfish. This native of the Indo-Pacific region has exploded throughout the tropical and temperate western Atlantic. They are prolific breeders and efficient, voracious predators of small and juvenile fish, including groupers.

The lionfish also have benefitted from the apparent absence of predators that will eat them. In the Pacific, where they belong, lionfish tend to be fairly shy ambush predators whose numbers are checked by larger predators, including groupers and sharks.

The lionfish in Turks and Caicos were not as numerous as their cousins in the Bahamas, Roatan and North Carolina in recent years, and they were not as large. I don't know if the groupers, sharks, rays and barracuda of Turks and Caicos have acquired a taste for lionfish, but that could be one reason for the healthy balance we saw there.

Most of what I read and hear -- and see with my own eyes -- about the state of the world ocean is extremely pessimistic, so the best part of the Turks and Caicos for me was seeing a reef that seems to be healthy and relatively well balanced, and the sharks were one of the major bits of evidence. It will take a lot more marine protected areas to level off the damage we are doing to the oceans and to ourselves, but this is a place that gives you hope it can happen.

The Virtues of Envy

I like it when people say they envy me. I've been hearing that a lot lately, especially in the last week or so, since I joined old friends from Maryland on a liveaboard dive trip to the Turks and Caicos Islands


It was somewhat surprising to hear that on the boat, since we were all doing the same thing. To the dedicated diver, liveaboards are the best way to go. You set up your gear at the beginning of the week and spend the next seven days diving, eating and sleeping. It's the perfect way to "front the essential facts of life," as Thoreau envisioned himself doing at Walden Pond. I'm sure he would have included scuba diving as one of the essential facts along with eating and sleeping, if scuba gear had been invented back then. 


The boat we were on, the Turks and Caicos Explorer, is one of the nicest I have had the pleasure of boarding. The boat is big (124 feet), spacious, steady, sturdy, well appointed, serves great food and, at least last week, had a professional, attentive and fun-loving crew. And the diving was some of the best I've seen in the Caribbean (more about that in a near-future blog post). 


Furthermore, the weather was almost perfect, and even though we were well on the other side of the Tropic of Cancer, it was a damn sight more pleasant than the scorching temperatures of the DC area and the Midwest (two of the divers had escaped from Kansas). The constant trade winds over the water moderate the temperature, and the occasional brief tropical rain can almost make you want a sweater.


A view that inspires gratitude
Anyway, since everyone aboard was doing the same thing I was, why would any of them envy me? For some of them at least, it's easy to understand. They're still working for a living, while I and several others have passed on to the world of no deadlines, no bosses, no staff and many other things that used to dominate our lives. 


Since I returned, I've heard more understandable but equally welcome envy from non-diving friends, too, and it finally dawned on me that this sort of envy is a positive thing, not a destructive, soul-tormenting jealousy, but rather an appreciation.


I claim no virtue in having reached this state. Yes, I worked and earned most of my retirement income, but I am also incredibly lucky. Not everyone these days can even think about retirement, and that is very sad. My generation may be the last in America that can not tell our children they have a good chance of living better than we do. 


All of that contributes to the feeling of gratitude I have when I go off to the Turks and Caicos or some of the even more exotic trips I'm planning soon. I have no sense of entitlement. Indeed, when I think about it, I'm most grateful that I didn't get everything I deserved in life. 


May envy lift you high enough to see it all.
What I did get is the opportunity to do what I'm doing now, traveling, photographing places and wildlife and sharing what I see with anyone who's interested. 


If people envy that, as so many have said they do lately, well, that just confirms for me that I'm doing what I should be doing, seizing the opportunity to live the life I have dreamed of. Some people might live through me that way. I hope that more will do the same thing, no matter what their dream life is (as long as they're not hurting other people and creatures, of course). 


By the way, there are people I envy, too. Not because I want the life they have necessarily, but because they are living their own dreams, often in the face of serious challenges. They weren't given the opportunities I've had; they had to make their own, and the value of what they do is magnified many times over.
