Flatworms, Roundworms, Annelids, Mollusks, and Arthropods
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.
Many flatworms can detect changes in the amount of light in their environment using groups of cells called photoreceptors. These cells are sensitive to light and help the flatworms navigate and respond to their surroundings based on light levels.
