annelid
Ringed invertebrate crawler
An annelid is a segmented worm—an invertebrate whose body consists of repeating ring-like sections.
The phylum Annelida includes earthworms, leeches, and marine worms like lugworms and ragworms.
Annelids play a crucial role in soil aeration.
The adjective describes anything relating to these creatures: annelid anatomy.
