Great article. As I have thought for awhile a lot of scolymias ( or what is sold as scolymias in the trade ) are not scolymias. Many of the most beautfiul corals are in fact Acanthophyllia. Now Sprung takes issue with the current taxonomy of calling Acanthophyllia, a Cynaria and explains why. But properly described, most scolys sold today are really Cynaria. I tend to agree with Sprung that translucent and opaque Cynaria makes a very diverse genus and maybe that should be rethought.
