     Note: They are often coralike in form and appearance, each
           small cell containing an individual zooid. Other
           species grow in delicate, flexible, branched forms,
           resembling moss, whence the name. Some are found in
           fresh water, but most are marine. The three principal
           divisions are {Ectoprocta}, {Entoprocta}, and
           {Pterobranchia}. See {Cyclostoma}, {Chilostoma}, and
           {Phylactolema}.
