Diagnosis

Actiniidae with well developed base and smooth column rarely provided with a cuticle. Margin and fosse distinct. Sphincter usually circumscribed, often strong, rarely restricted. Tentacles simple, short, not attenuated at the base. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal to more or less mesogloeal. Mesenteries hexamerously arranged. Younger mesenteries growing from the base to the margin wherefore there are usually more mesenteries at the base than at the margin. At least 12 pairs of mesenteries perfect. Retractors diffuse to restricted, often very strong. Gonads in all stronger mesenteries. Cnidom: spirocysts, basitrichs, microbasic p-mastigophores. Embryos often developing in brood-pouches or adherent to column.
