A key feature of flatworms is their bilateral symmetry, which means their body can be divided into two mirror-image halves. They possess a flattened body shape, allowing for increased surface area for gas exchange. Flatworms also have a simple nervous system with a pair of cerebral ganglia and longitudinal nerve cords, as well as a unique digestive system that often includes a gastrovascular cavity. Many species are also hermaphroditic, possessing both male and female reproductive organs.
