In response to Jeremy's comment,  I hate to see coral-list degenerate to
answering basic questions that are so fundamental to basic training that
they indicate that whomever asked them hasn't bothered to do any background
reading before undertaking a research project.  Is this indicative of the
level of training of young 'scientists'  hese days?  Anyone that plans to
do research on corals should have read through Libby Hyman's works,
Chapman, and all sorts of "old" 1960's papers and chapters.   Doesn't
anyone know how to use a library anymore?
