update to our question on lesions on Millepora:
We have posted the question and pictures below to "coral-list", a coral expert discussion group. You can follow the threat at the Coral-List Archives.

Stephan Moldzio's question regarding the round bare patches on Millepora prompted a reply from me that I believed they were made by the spotted coral blenny, Exallias brevis. That in turn led to several people writing directly to me for more information. Since this fish is not well known, and since I have never published my data and photos (but I intend to!), I thought that it would at least be worthwhile to post some images of this fish on YouTube. Every coral biologist working in the IP region should recognize the feeding scars that this fish can make. I have a suspicion that some reports of disease or spotty bleaching may in fact simply be feeding scars from Exallias.

Also from the Caribbean similar marks have been reported: (photos from Rosa Rodriguez-Martinez from Puerto Morelos reef ):

Recently we have noticed circular spots on Millepora in the Egyptian Red Sea as seen in the pictures below.
If you have seen similar phenomena on Millepora, or if you have an explanation about the cause, we would appreciate if you drop a message to Stephan Moldzio at Diese E-Mail-Adresse ist vor Spambots geschützt! Zur Anzeige muss JavaScript eingeschaltet sein!
