Developmental expression of Amgalaxin. Expression begins as an aboral submarginal ring (A-B) Septal expression is then added (arrows) as the polyp grows older (C-F). There is also sometimes aboral granular expression between the septa (E). Septal expression continues in the oldest polyp studied (F). (A), (C) and (E) are viewed aborally, (B), (D) and (F) are viewed orally.
