In samples collected from the harbour at Antifer (Normandy, France), a great number of Dinophysis cf. acuminata cells had retracted cytoplasm within a circular disc. We observed the release of a temporary cyst similar to other temporary dinoflagellate cysts. Several daughter cells still attached to the empty theca of the mother cell D. Sacculus showed apparently the shape and morphology of D. skaggi. This suggests that these small size cells are not different species but only morphotypes of Dinophysis' biological cycle.
