Similarities between Humans and Flatworms

Flatworms: The Phylum's Animal Members
Since their bodies are dorsoventrally flattened, platyhelminthes are sometimes known as flatworms. These soft-bodied, bilateral, unsegmented, and straightforward invertebrates can range in size from single-celled organisms to two to three feet in length.
Flatworms in the Ecosystem
An ecosystem is a place where one or more communities coexist and prosper, with interactions between living and non-living elements. While many flatworms in this phylum are internal parasites, freshwater flatworms primarily prey on and scavenge soft-bodied invertebrates. They have adapted to survive in various environmental conditions.
