In flatworms (Platyhelminthes), they have a tegument which is a living outer layer. As a parasite living in the gut of the host, it wants to absorb nutrients from the medium around them, therefore it is important that they have a metabolically active outer layer for vital activities such as absorbtion, protection and secretion.
On the other hand, roundworms (Nemathelminthes) have a rigid outer cuticle which works with the muscles to create a hydroskeleton. It has a digestive system which starts with a mouth and ends at the anus.
This is significant from a medical point of view as this characteristic, having a cuticle
or tegument determines what kind of drug is used to treat the parasite. Some drugs can destroy the living outer layer of a tapeworm, while other drugs are ingested by the roundworms which then attacks the lining of their gut.
It makes a fantastic corrosive solution for dissolving organic material such as the collagen cuticle of the roundworm C. elegans, while not being strong enough to dissolve more hardy materials such as chitin eggshells.
