The endozoic dinoflagellate Symbiodinium (=Gymnodinium) microadriaticum (Freudenthal) was isolated from six coral reef-dwelling invertebrates: Aiptasia tagetes, A. pallida, Bartholomea annulata, Cassiopeia xamachana, C. frondosa, and Tridacna gigas. These isolates were grown in mass culture in ASP-8A for over 9 months under constant conditions of temperature and illumination.

The algae in culture demonstrated a marked rhythm in motility. The cells swam only during the light period of a 14:10-h light:dark photoperiod. Different identified strains demonstrated characteristic patterns of motility. Results suggest that the patterns of motility are under the control of an endogenous rhythm.
