A large class of sedentary marine coelenterates that includes the sea anemones and corals. They are either solitary or colonial, and have a central mouth surrounded by tentacles.
‘The Anthozoa (sea anemones and corals) possess only the polyp form.’
‘In the context of relationships among cnidarian taxa assigned the Linnaean rank of class, Anthozoa may be perceived as basal.’
‘In any case, there is molecular evidence to suggest that the Anthozoa are the earliest branch of the phylum Cnidaria.’
‘Their phylogenetic positions, within Medusozoa and Anthozoa respectively, do not provide any information about whether these animals retain ancestral states for other characters under study.’
‘Color diversity and the corresponding complexity of the protein organization evolved independently in several Anthozoa lineages, as well as in Hydrozoa.’
Origin
Modern Latin (plural), from Greek anthos ‘flower’ + zōia ‘animals’.
