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. =)

What features do Segmented Worms have?
Segmented worms, also called annelids have body parts that are duplicated in each segment. If one segment is damaged, some annelids can survive. They also have setae, or two pairs of hairs found on each segment. These hairs grip the soil and get around more efficiently.
Why are annelids more complex than nematodes and platyhelminthes?
Annelids have a more complex body plan than nematodes and platyhelminthes because they have segmented bodies with specialized structures like bristles (setae) and a closed circulatory system. This segmentation allows for more specialized functions in different body regions, giving annelids a higher level of complexity compared to the more simple, unsegmented body plans of nematodes and platyhelminthes.
What are annelids?
Annelids are a type of segmented worms found in marine, freshwater, and terrestrial habitats. They have a cylindrical body with ring-like segments and exhibit bilateral symmetry. Examples of annelids include earthworms, leeches, and marine bristle worms.
