Flatworms have bilateral symmetry. Bilateral symmetry means the animal has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

A. Flatworms were the first organisms to exhibit bilateral symmetry.
Bilateral Symmetry
Platyhelminthes exhibit bilateral symmetry, meaning they can be divided into two equal halves along a single plane. This symmetry type allows for better movement and coordination in these flatworms.
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.
Bilateral symmetry.
Annelids exhibit bilateral symmetry, meaning they can be divided into two equal halves along a single plane. This symmetry allows for efficient movement and body organization in these segmented worms.
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.
