<h2>Anterior-posterior orientation</h2>

Explanation:

Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established

Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
