The features of flatworms in comparison to the protostomes and deuterostomes. Enlist the similarity and dissimilarity among these groups. Concept Introduction: Flatworms are included under the clade protostomes. Protostomes included those animals in which mouth arises first from the opening in blastopore. Flatworms are unsegmented and free living parasites. They have bilateral symmetry and contain three germ layers. Flatworms have flattened body shape. Deuterostomes are those in which anus arises from the first opening in blastopore.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
