[en] The gastropod Coralliophilla meyendorffi is a common predator of the zooxanthellate anemone Anemonia viridis. Zooxanthella
from the anemones are an important constitutent of the mollusc faeces. Cell integrity, occurence of flagellated forms, live/dead
proportions and mitotic index of Symbiodinium collected from the faeces and cultivated in vitro were examined and compared to that
of algae in hospite. The results show that most algae withstand digestive processes of the predator, staying alive and dividing actively
in the faeces. Motile (lagellated) algae arise from dividing cells and escape the fecal pellets. Impact on coral bleaching recovery is discussed.
