A parapodium is a lateral, paired appendage found in some marine annelid worms, specifically in polychaetes. It is used primarily for locomotion but also serves in respiration and sensing the environment. It can vary greatly in structure but typically consists of a proximal segment attached to the body and a distal segmented branch.

[Renato]

Parapodia, singular parapodium, are paired, un-jointed lateral outgrowths from the bodies of two different invertebrate groups, which are primarily marine in habitat. These structures are characteristic of Polychaeta, and several clades of sea snails and sea slugs.
