[alga.sup.-1].[d.sup.-1]) of a zooxanthella at 50% of the average hourly irradiance is over twice that of a zoochlorella during summer, the two algae exhibit comparable daily productivities during winter (Table 1).
In 1881, Brandt introduced the term zoochlorella to describe the algae in freshwater hosts, including hydras, sponges and protists (Sapp, 1994).
Also, in the Hydra-Chlorella symbiosis (reviewed by Schoenberg and Trench, 1980), it has been suggested that recognition follows nonspecific phagocytosis of a zoochlorella by a host digestive cell.
