Annelida

These are the segmented worms, including earthworms, leeches, and ragworms. Polychaetes make up most of this phylum and are among the most common marine organisms. All polychaetes have bristles on their paddle-like appendages, which run down the sides of their bodies. As such, they are also known as bristle worms.
