Turbellaria

Turbellaria forms a class of flatworms characterized by their soft, flattened bodies and free-moving behavior. They are primarily aquatic, inhabiting freshwater, marine, and damp terrestrial environments. Turbellarians have a simple but effective body plan with a nerve net, sensory organs, and a muscular system allowing them to glide smoothly over surfaces. Known for their regenerative abilities, they can often replace parts if damaged. These organisms play important roles in ecosystems as predators or scavengers, helping control populations of smaller invertebrates, and serve as model organisms in scientific studies of development and regeneration.
