Turbellaria is a class within the phylum Platyhelminthes, encompassing mostly free-living flatworms. These aquatic or terrestrial worms are known for their soft, ciliated epidermis, which they use for locomotion. Imagine gliding along a surface using tiny hairs! They range in size and color and are often found in freshwater environments. Many turbellarians are predators, feeding on small invertebrates. Planarians are the most well-known example of this class. They showcase remarkable regenerative abilities.
