History and Etymology for zooxanthella

borrowed from New Latin, originally a genus name, from zoo- zoo- + Greek xanthós "yellow" + New Latin -ella, suffix in names of microorganisms, going back to Latin, feminine of -ellus, diminutive suffix, originally from bases ending in -ul-, -r- or -n- — more at xanthophyll

Note: As a genus name, Zooxanthella was introduced by the German marine biologist Karl Brandt (1854-1931) in "Ueber das Zusammenleben von Thieren und Algen" ("Verhandlungen der physiologischen Gesellschaft zu Berlin," "Nachtrag zur Sitzung von 11. November 1881"), Archiv für Physiologie, Physiologische Abtheilung des Archives für Anatomie und Physiologie, Jahrgang 1881, p. 572.
