A taxonomic group (phylum Annelida or class Annulata) comprising segmented worms with ring-like body segments.
From Latin annulatus ('ringed' or 'having rings'), from annulus ('ring'). Scientific classification term adopted into taxonomy for ring-segmented organisms.
Earthworms, leeches, and polychaete worms are all annelids—they're 'ringed' because their bodies are divided into identical segments, a design so successful it's been virtually unchanged for 500 million years!
