Worms are not insects. Insects are in the Phylum Arthropoda, in the class Insecta. All Arthropoda have jointed body parts while Annelids are segmented but not jointed. Earthworms are in the class Oligochaeta (meaning they are segmented worms with only a few bristles). There is a bigger difference worms and Insects than between a Reptile and a Mammal.
Annelida â This group is probably the most recognized of the three worm classifications. Phylum Annelida includes some sea worms, but it is mostly comprised of segmented worms such as earthworms. Earthworms are also an unofficial broad classification of worms. Hundreds of different worm species in 16 families are considered earthworms. Earthworms are also divided into three subcategories depending on their ecosystem.
