2. Annelid: The term annelid derives from the French word for “ringed ones.” Annelid refers to a large phylum of segmented worms, including earthworms, ragworms, and leeches. Segmented worms often have similar sets of organs located in each segment. My example was a dead earthworm that I found on the sidewalk. Earthworms are obvious examples of annelids because as many people are aware, cutting an earthworm in half will not kill it. This is because of its segmented structure consisting of more than one set of organs.
