Sharon , yes the Crown of Thorns in certain areas of the Barrier Reef have threatened coral species to the point where it was causing mass coral destruction and had to be kept in check as they were becoming a nuisance...

SQinfoNUTS, it's not so much the individual size but the sheer numbers in some parts of the world that causes so much destruction. they no longer have the natural predator in certain areas so they breed like crazy with nothing to check them.
