Called a Lion Fish, it is extremelly dangerous. Each dorsal spine has poison, comparable to that of a rattlesnake. The tip is like a hock that cannot be removed esily, with great pain. It is the new threat in the Caribbean, where it did not exist until about 10 years ago (It lived in the Pacific ocean) and is now spread all over the Caribbean Sea. It is one of the most beautiful fish though ... and this is a superb image of it.
