Flatworms can be either parasites, which live in their hosts, or planarians, which are marine (water) oriented.

I Think It Lives In The Water Where It Is Deep And Dark.
Flatworms include both endoparasitic and free-living species. Many flatworms, such as tapeworms and flukes, are indeed endoparasites that live inside the bodies of their hosts, often causing harm. In contrast, other flatworms, like planarians, are free-living and found in aquatic environments. Thus, while some flatworms are endoparasites, not all flatworms fit this classification.
Flatworms are divided into two groups, parasitic and nonparasitic. The parasitic types, which live off of other organisms, consist of Cestoda, Trematoda, and Monogenea flatworms.
most the time they live on live rock but they are usually found on corals as well.
flatworms live in lakes and rivers. they also dont have a resptory or a circulatory system. they eliminate wastes through the body walls using diffusion.
Free-living flatworms are flatworms that live independently in their environment, rather than parasitizing another organism. They are typically found in freshwater or marine habitats and feed on microorganisms, small invertebrates, and organic matter. Examples include planarians and marine flatworms.
