Desmophyllum dianthus (Esper, 1794) in the scleractinian phylogeny and its intraspecific diversity.

The cosmopolitan solitary deep-water scleractinian coral Desmophyllum dianthus (Esper, 1794) was selected as a representative model species of the polyphyletic Caryophylliidae family to (1) examine phylogenetic relationships with respect to the principal Scleractinia taxa, (2) check population struc...
