In this regard, are nematodes radial or bilateral?
Nematodes are tiny roundworms that may be parasitic. Nematodes have bilateral symmetry, which means there is a line lengthwise that can divide them into two equal halves that are mirror images. The heads of nematodes have radial symmetry which means that any line drawn through the center produces mirror images.
Similarly, how are roundworms and flatworms different? Roundworms are more cylindrical in shape and tapered to a fine point at one end. Flatworms are covered with cilia, hairlike growths. Flatworms are acoelomate, which means they do not have a body cavity. Roundworms are psuedocoelomate, which means they have a body cavity between their mesoderm and endoderm layers.
