What type of Coelom is found in roundworm?
What do roundworms have rather of a Coelom?

Segmented worms likewise tend to have organ systems that are more industrialized than the roundworms’ or flatworms’. Earthworms, for instance, have a total gastrointestinal system with 2 openings, along with an esophagus and intestinal tracts.
What is the distinction in between parasites and totally free living worms?
