An archaic or obsolete zoological classification or order of small arthropods, possibly early or alternative name for copepods or similar creatures.
From Greek kopeîs (rower) plus gnatha (jaw). An older scientific term likely from 19th-century zoology before modern taxonomy standardized names for tiny crustaceans.
Early zoologists literally called copepods 'rowers with jaws' because of how they move through water—before we had microscopes good enough to describe them accurately!
