Meaning and Usage

Polychaeta refers to a class of annelid worms that are primarily marine. They are characterized by their segmented bodies and many bristle-like appendages (chaetae) on each segment, which aid in locomotion and respiration. Polychaetes play significant roles in marine ecosystems, often acting as both predators and prey within the food web.

In the English language, "polychaeta" is predominantly used in scientific contexts, particularly in biology and zoology. It is less common in everyday conversation, so its frequency of use is low in informal contexts but potentially higher in academic or professional settings.
