a quick movement
The head of Dugesia moves forward using its cilia for swimming and feeding, while the tail mainly helps with balance and stability. The head can also sense changes in the environment and respond to stimuli, while the tail primarily functions in locomotion.
Dugesia has distinct features that differentiate its head from its tail. The head typically has a pair of eyespots that detect light, while the tail tends to be more tapered and lacks sensory organs. In addition, the head region may exhibit a more active behavior, such as seeking out food sources, compared to the tail.
