Edited by Huma Saeed || By Sumera Saeed || Updated on October 26, 2023
Annelida are segmented worms, while Arthropoda are invertebrates with exoskeletons and jointed appendages.
Key Differences
Annelida, or segmented worms, have bodies divided into ring-like segments. Arthropoda, the largest phylum, includes creatures with exoskeletons and jointed limbs.
