Platyhelminthes are flatworms. they have bilateral symmetry. most have only one body opening if that. they can be parasidic or free living. Platyhelminthes reproduce sexually. They are hermaphoditic, which means they have both male and female sex organs and when they repeoduce they both become fertilized. they do not have a true circulatory or respiratry system, they exchange gasses through diffusion.
