Type species: Sertularia loricata Linnaeus, 1758
Colony erect, tufted, much branched, attached to the substratum by a cluster of rhizoids. Branches composed of pairs of zooids joined back-to-back (ie by their basal surfaces), each giving rise disto-basally to the next pair, all the pairs orientated the same way. Branches generally originating alternately to the left and to the right of the main axis, the first autozooid in the branch arising disto-laterally on its parent; the branches themselves dividing dichotomously. Zooids elongated, narrow proximally. Frontal membrane oval, situated in the distal part of the autozooid. Spines and avicularia absent. Embryos developing in membranous evanescent ovisacs, not in ooecia. (Hayward & Ryland, 1998)
