dinoflagellate Scientific  
/ dī′nō-flăjə-lĭt /
  1. Any of numerous one-celled organisms found mostly in the ocean, usually having two flagella of unequal length and often an armorlike covering of cellulose. Dinoflagellates are one of the main components of plankton. Since dinoflagellates have characteristics of both plants and animals, their classification is controversial.

Pronunciation

At first glance, it would seem that dinoflagellates are related to dinosaurs, at least with respect to their names. Despite both words beginning with the spelling dino-, however, their etymologies and pronunciations are very different—as are their sizes! The first part of dinosaur comes from the Greek root deinós (“terrifying, frightful”) and is pronounced . Dinoflagellate gets its start from the completely different Greek root dînos (“whirling, rotation”), and is pronounced . With a characteristic corkscrew motion producing a spiral path, the microscopic dinoflagellate is really not terrifying at all.

Etymology

Origin of dinoflagellate

First recorded in 1900–05; from Greek dînos “rotation, whirling” + flagellate
