Jan, The photographs of Palythoa at your website
<http://www.flickr.com/photos/23314528@N03/> are excellent. I have
taken many similar photos of this species overgrowing Montastrea in
the past but not as good as those at this website. I can say that I
remember seeing such over growths in Florida in the 1950s and 60s
but it never seemed extensive. I pealed it off on several occasions
to see if was actually killing underlying live Montastrea. It was but
it was always small patches. It appears to start on dead spots and
then expand over adjacent live tissue. It certainly forms huge mats
on dead reef tops such as at Looe Key reef. I suspect storms,
especially hurricanes keep it in check. Gene
