None of the above - it's an invertebrate ! Which is why I moved the question into the worms category from snakes !AnswerIndeed, all worms are invertebrates whereas all the groups you mention in your question are classes of vertebrate. Specifically, earthworms are annelids, coming from the phylum of segmented worms, Phylum Annelida.
This is determined by one simple fact - does it have a spine (segmented backbone ) or not.
