Ответ:
Phylum platyhelminthe
Explanation:
Although a few of the free living marine and terrestrial species are very beautiful, most species are not particularly attractive to the human mind. Their body is dorso-ventrally flattened. They exhibit bilateral symmetry. They do not have a body cavity and are acoelomate. The movement of most platyhelminthes is using a wavelike motion that is controlled by longitudinal, circular, and oblique layers of muscle as they contract and relax simultaneously.
