WebMembers of the Phylum Platyhelminthes are typically called flatworms because of their flattened bodies. These animals lack appendages, and their bodies can take many forms, such as slender, leaflike, or ribbon-like. This diverse group of bilateral invertebrates ranges widely in size from 1mm or less to tapeworms that grow to many meters in length. WebFlatworms are bilaterally symmetrical with a defined head and tail region and a centralized nervous system containing a brain and nerve cords. Clusters of light-sensitive cells make up eyespots on either side of the head. The head region of the flatworm also contains other paired sense organs, which are connected to the flatworm’s simple brain.
