Actinozoa
OBSOLESCENT TERM IN SYSTEMATIC ZOOLOGY
Actinozoa is an obsolescent term in systematic zoology, first used by Henri Marie Ducrotay de Blainville in his Manuel d'Actinologie (1834) to designate animals the organs of which were disposed radially about a centre. De Blainville included in his group many unicellular forms, sea anemones, corals, jellyfish, hydroid polyps, echinoderms, polyzoa, and rotifera.
