Morphology

Polychaeta = chaeta (semi-transparent) = poly + chaeta

The form is literally built from 'poly' + 'chaeta' ('many bristles'), but as a taxonomic class name it is a specialized scientific label rather than an everyday descriptive word.

Etymology

Polychaeta comes from Greek parts: poly- 'many', as in polygon, and chaeta 'hair' or 'bristle'. These worms have many bristled legs along their body, so the name means 'many-bristled' and helps explain their look.
