bilateral
Marine flatworms exhibit bilateral symmetry, meaning they have a single line of symmetry that divides their bodies into two mirror-image halves. This symmetry allows for a more streamlined shape, which is beneficial for their movement and lifestyle in aquatic environments. The plane of symmetry typically runs down the center of their body, from head to tail.
Marine flatworms typically have a flat, ribbon-like body with distinct bilateral symmetry, while nudibranchs have a soft body with external gills on their back and often colorful patterns. Additionally, nudibranchs belong to the mollusk group, while marine flatworms do not.

Bilateral Symmetry
Flatworms exhibit bilateral symmetry, which means that their body can be divided into two symmetrical halves along a single plane. This type of symmetry allows for the development of more complex body structures and directional movement.
