[Coral-List] What it means that Florida Aquarium reported captive reproduction of a Mycetophyllia.

And this corresponds to something that zoos have been doing for quite a
while, part of efforts to save species.  The Science paper by Carpenter et
al, (2008) "One third of reef building
    corals face elevated extinction risk from climate change and local
impacts" raised the specter that at some point coral species may be at
immediate risk.  Although few if any coral species have been in immediate
danger of extinction in the past, that is changing, and the thin end of the
wedge is presented in a new article I referred to a little while ago:   "Coral
mass mortalities in the Chagos Archipelago over 40 years: Regional species
and assemblage extinctions and indications of positive feedbacks"
