The story of the word

Victor Hensen coined plankton in 1887 from πλαγκτός, wandering, the adjective behind the Πλαγκταί of the Odyssey, the Wandering Rocks. Biologists then split the drift into a plant half and an animal half. Drifting is the definition, not a description of laziness: these organisms cannot hold a position against a current, whatever they do vertically.
