What’s as blind as a bat, and will bite where its at? That’s a moray!

In the Caribbean, there are 15 or so kinds of moray eel. Based on my antidotal observation, the green moray is the most common. Green moral eels tend to grow larger than their cousins so perhaps their ability to grow larger gives them an advantage in the wild. Based on my personal observation around the Caribbean, the spotted moray is the second most common moray eel to see.

Here is an example of a spotted moray eel. spotted moray eel

Ordinarily, moray eels are relatively unaffected by the presence of divers. Quite often divers can get relatively close to moray eels before the eel will withdraw into the reef to avoid contact with a diver, but not always.

 

As I approached this moray eel he withdrew into the reef leaving the banded shrimp who had previously been cleaning the eel.

Sometimes during the daytime, eels will only peer out of their hiding holes in the reef and you have to be fairly alert to spot them. Green moray peeking out of the reef

Sometimes if you are very fortunate you will see a moray eel freely swimming about the reef. Generally speaking, you are more likely to see a free swimming moray eel during a night dive when they are hunting for food than you are during the day.

The relationship between divers and eels does change if there is food that is present or the eel believes that there may be food available. When food is present, the moray can become much more interested in the food than anything else. We were diving in Belize on the Turneffe reef when I saw a moray become much more interested in food than anything else. Our dive leader had speared a lion fish and were swimming along a wall when a moray caught the sent of the dead lion fish which was still on the spear. Here is how that interaction played out. Nevertheless some moray eel have no interest in lion fish as food even when dead.

Sometimes even if the feeding by has not occurred by humans for quite a long time, a moray eel will continue to look for a free meal. occasionally, the interaction between divers and an eel can be almost comical. Unfortunately, feeding wild animals can change their behavior. That applies not just to moray eels but to other animals as well.

Nevertheless, getting to see a free swimming moray eel, particularly in the day time, is quite a treat. And, while they are technically fish, moray eels are quite different from most fish that you see in the ocean.

Here is a short clip of some moray eels I have seen recently.

Do you look up when diving?

Not long ago I read an article that talked about how divers often became mesmorized by looking where the fish are, mostly near the bottom and often under ledges and over hangs. The problem the author said was that sometimes the most interesting things were swimming over the heads of the divers who missed them because they did not look up.

With that thought in mind I recently dove the Odyssey in Roatan Honduras. As briefed the dive was to have a maximum depth of 100 feet. We would not stay there very long and then we would gradually make our way up a wall near the wreck. As we got down to the wreck I shot some video of the wreck which is quite large. Here is my dive buddy Tony checking out part of the wreck. https://www.flickr.com/photos/bcampbell65/20074724821/

Midway through the dive I turend off the video and switched to stills. I looked up and overhead there was an enormous grouper that was swimming. He was easily 5 feet in length. I thouht about leaving the strobes on, but thought a silhouette of the fish might be interesting. During the rest of the dive we saw some black groupers as well and they were also in the 4 to 5 foot in length range.

Glad I looked up to see such incredible animals. Here is some of the video from the wreck dive:

Over the last decade or so we have been making our way around the Caribbean. My first encounter with a Lion fish was about 10 years ago when I heard that this invasive species from the Indo-Pacific region was slowing making its way around the Caribbean. I cannot say that I have been to every island in the region, but I have come close. I have seen them as far south as Tobaggo. I’ve seen them as far north as Florida. I have seen them as far east as Barbados. I have seen them as far west as Roatan, Cozumel and Playa del Carmen. Lion fish are eating and reproducing machines. A marine biologist in Belize told me that the female lion fish produces about 40,000 eggs every 3 days. The reproductive ability of rabbits pale by comparison.

One of my friends in Barbados let me know that last week his shop shot 90 lion fish while my friends in Roatan shot over 130 last week. There are lion fish round ups throughout the Caribbean. I have seen roundups in the Caymans, and Curacao and Belize. Ultimately, the lion fish has no natural predators in the Caribbean. Although there have been efforts to train moray eels, groupers and sharks to feed on them, often it still requires the spearing of the fish in the first instance. I don’t know what the answer is, but I certainly hope we find a better answer than we have now because from what I have seen we appear to be losing the battle.

Some might say so what. The problem is that with depleted native species, like parrot fish and others who eat the algae off the reef the reefs could eventually die out. I think about the great limpet that only resides in Monterrey bay and wonder, can we really afford such a loss. There are proteins that are created by the great limpet that make cancer drugs more effective and which at the present have not yet been synthesized. The proteins from the limpid sell for about $34,000 per gram or more than 600 times the price of gold. I wonder can we afford to lose even one species of flora or fauna in the Caribbean? I keep wondering if there is a better solution to removing this invasive species. Yet at the same time i think about instances in which people have introduced one invasive species to remove another and those efforts have gone terribly wrong,consider africanized bees….
