Interesting story....Caribbean reefs are in big trouble almost everywhere. One place where they seem to be, if not hale and hearty, at least hanging in and making a bit of a comeback, is Little Cayman. They have the same ocean warming, acidification and related climate change issues as everyplace else, so how can this be? Short answer: heavy enforcement to prevent overfishing and regulation of runoff water from land. Read the whole thing for details.

(comments at the place where I found this suggest the reporter said "parrotfish" when it should have been "grouper." That commenter dives in the area on a regular basis, which I, alas, do not, so will consider this an informed source.)
