Other Platyhelminthes characteristics shared by these creatures is they are bilaterally symmetrical, this means the left and right sides of their bodies are mirror images of each other. They have distinctive head and tail ends and their body contains three cell layers.
Platyhelminths, or flatworms, include both free-living and parasitic species. The phylum Platyhelminthes is divided into two monophyletic clades, the Catenulida (with just around 100 known species; Larsson and Jondelius 2008) and the Rhabditophora, which includes nearly all known platyhelminths (Timothy et al. 2004; Willems et al. 2006; Larsson and Jondelius 2008).
