While the mode of zooxanthella acquisition has been determined in relatively few species of cnidarians, early indications are that infection prior to fertilization is quite uncommon.
Baseline samples of bell margin tissue were taken from eight freshly field-collected symbiotic jellyfish (acclimated in the field to a light intensity of about 1000 [micro]E) and were fixed or frozen as described below for determination of zooxanthella density and CA activity and localization.
Moreover, zoochlorellae translocate, to the host, photosynthetic products that differ qualitatively from zooxanthella photosynthate (Minnick and McCloskey, cited by Verde and McCloskey, 1996), and zooxanthellae contribute more reduced carbon to the host's nutrition than do zoochlorellae (Verde and McCloskey, 1996).

Accordingly, any direct interaction s among different species of Symbiodinium were thought to result in one species of zooxanthella consistently "winning" and therefore specifically and exclusively populating its host (Fitt, 1985a; Trench, 1988, 1993).
