Venn diagram of shared and unique PFAM-A domains amongst sea anemones and complex and robust corals. Set membership counts shown without parentheses consider a domain to be present in a lineage if it is found in any of the species in that lineage. Numbers in parentheses indicate set memberships calculated with the requirement that the domain is present in all species in that group. In the situation where corals of the complex or robust lineages form a group with anemones, the domain is counted when it is present in all coral species and either of the sea anemones
