Abstract. We investigated morphology, dynamics and origin of cells surrounding the mouth of Hydra vulgaris using the monoclonal antibody L96. This antibody recognises a one cell-thick ring of endodermal epithelial cells exactly at the boundary between endoderm (gastrodermis) and ectoderm (epidermis). L96+ cells can stretch considerably without any cell rupture during mouth opening. Thus, our data prove the existence of a distinct cell population defining hydra’s mouth. A model for mouth opening is proposed and the significance of L96+ cells for boundary formation between ectoderm and endoderm is discussed.
