Turbellarians are a class of soft-bodied, mostly free-living flatworms found in various aquatic environments, including freshwater, marine, and moist terrestrial habitats. They are characterized by their flattened bodies and ciliated surfaces, which help them move through water and across surfaces. Turbellarians typically feed on small organisms, using their muscular pharynx to capture prey. These organisms are known for their remarkable regenerative abilities, allowing them to regrow lost body parts. Turbellarians play an important role in ecosystems as both predators and prey, contributing to the balance of aquatic food webs. They are also studied in biological research for insights into regeneration and development.
