Answer: Flatworms, Roundworms and Segmented worms
Explanation:
These are not all placed in a phyla because the degree of developmental and morphological similarity is low.
The flatworms also known as platyhelminthes do not have coelom, no respiratory system or a circulatory system. An example is the tapeworm.
The roundworms also known as nematodes are slightly more complex than the flatworms in that they have a pseudocoelom and they are bilaterally symmetrical. An example is Ascaris lumbricoides.
The segmented worms are the most complex of them in that they have a true coelom, a circulatory system found in each segment and a digestive system. An example is the earthworm.
