What features distinguish annelids from roundworms?
There's many of them, but here are some of the bigger ones; Annelids, unlike roundworms (or flatworms for that matter) are segmented. That is after all how they get their name (annelida = little ring). Annelids also have a very complex organ system. Roundworms only possess a reproduction system as they usually live in an organism's intestines and don't need to digest food. Annelids posses both a reproduction system, and a digestive system as well as a circulatory system. As they are true coelomates their organs and organ systems are organised rather than just kinda' being tossed in there. =)
