One of the numerous green unicellular organisms, believed to be algæ, that are present as symbionts in the cytoplasm of many freshwater invertebrates.
1889in Cent. Dict. 1899F. S. Lee tr. M. Verworn's Gen. Physiol. ii. 84 Among such symbiotic organisms are especially many algæ, the Zooxanthellæ and the Zoochlorellæ, the nature of which as independent organisms has been for a long time in dispute. They occur abundantly in the cells of lower animals. 1924J. A. Thomson Sci. Old & New xxvii. 150 The same kind of co-operation is illustrated by a number of green Protozoa, in cases where the green colour has been shown to be due..to a partnership with minute algae (Zoochlorellae and Zooxanthellae). 1972M. S. Gardiner Biol. of Invertebrates i. 34/1 Zooxanthellae are limited to marine species, and zoochlorellae almost entirely to freshwater species. 1979Nature 5 July 58/2 Traces of chlorophyll b in extracts of pigments from intact animals suggested that Amphistegina spp. and Amphisorus hemprichii also contained symbiotic zoochlorellae. |
