| E. Nardin et al. 2017 | Blastozoans with a cylindrical to fusiform body wall. Part of the lateral body wall, made of numerous adjacent plates, with large elliptic simple sutural pores along their sutures. Ambu- lacral system confined to body-wall summit, consisting of a central mouth, several radially arranged ambulacral grooves embedded into the oral surface, and straight biserial brachioles, each mounted on two ambulacral flooring plates. Aboral region exclusively composed of numerous imbricate plates, overlapping adorally; proximal part (cup) forming the aboral part of the body wall; distal part (stalk-like extension of the cup) elongate and forming a rela- tively long and narrow, cylindrical attachment structure. |
