Turbellaria is 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 a simple body structure, lacking specialized respiratory and circulatory systems. Turbellarians typically have a muscular layer that allows them to move using cilia on their ventral surface. These organisms are primarily carnivorous, feeding on small invertebrates and organic matter. Turbellaria plays a crucial role in the ecosystem as both predators and prey, contributing to nutrient cycling. Some species are also studied for their regenerative abilities, making them of interest in scientific research.
