Etymology of polychaete
The term 'polychaete' comes from the Greek words 'poly' meaning 'many' and 'chaete' meaning 'hair'. This refers to the many bristle-like setae that are characteristic of polychaetes. The phylum Annelida, to which polychaetes belong, has been around for over 500 million years, and polychaetes have been a part of the marine ecosystem for just as long.
