[New interpretation of the symmetry of Cereus pedunculatus (Actiniaria) during embryonic development].
A spatial reconstitution is used to determine with precision the relative position of pharynx and mesenteries during the embryonic development of Cereus pedunculatus. Three successive stages are described for embryonic symmetrisation.
