Subgroups



The phylogenetic relationships of the anthozoans are not resolved and there is no universally agreed classification (see this summary of the debate). Anthozoa are traditionally divided into two or three groups, either recognising the black corals and tube anemones, which both have singly occurring mesenteries as a shared feature, as a subclass (Ceriantipatharia) or demoting them to orders within the Zoantharia. The latter scheme (of Hyman, 1940) is used here.
