Of note, marine life over there is somewhat unusual. On the plus side, crustaceans are very abundant and variable. Lots of huge clinging crabs, spotted lobsters, banded red lobsters, small shrimp like Pederson's and golden cleaning etc. Many Spotted morays and numerous Flying Gurnards in the shallows, I've never seen that many anywhere else. I counted 7 of the one day when snorkeling. Octopus, sea horses, frogfish were found too. There were some rarities, like I found a Golden Hamlet for the 1st time, though Newmann & DeLoach's book claims they are absent in the south Caribbean. On the down side, there are almost no angelfish there. Can you imagine a Caribbean reef with no angelfish? In 15 dives, I counted just 1 Queen and 1 French, both semi-juveniles, and maybe couple of Rock Beauties. Weird...Also, no Green morays, no groupers larger than 1 ft and no large parrotfish like Rainbow or Midnight. Sea turtles were few and they were very, very shy. Normally, I'd approach a turtle slowly to shooting distance and most ignore me or turn away slowly; I never chaise them. But this one turtle at St Lucia ran for her life when she saw me. I've never seen a turtle swimming so fast, must be a world record. Someone scared her to death previously.
