Internal and external difference between flatworms and roundworms

Both these worms may appear similar to each other but they have different internal and external features. Flatworms belong to the Phylum Platyhelminthes with over 20,000 Species collectively. Whereas roundworms belong to the Phylum Nematoda with over 16,000 parasitic species.

In general, flatworms are dorso-ventrally flattened while roundworms are more cylindrical and are tapered at both ends. Similarly, roundworms have a stiff external cover called a cuticle that they shed frequently during their lives as they develop. Flatworms are not equipped with this, as their bodies are embraced with cilia, hairlike growths.

Apart from this, flatworms frequently exist in bodies of water, while roundworm classes can breathe either on water or in soil. Talking about the internal features, flatworms do not have a body cavity as they are acoelomate. Also, they have a gastrovascular cavity, with only a single opening that functions as both mouth and anus. On the other hand, roundworms are pseudocoelomates, which indicates they have a body cavity separating the endoderm and mesoderm layers. Also, they have a complete digestive tract, with two separate openings for the mouth and anus. Apart from this, diversity is more eminent amongst roundworms as compared to flatworms.
