they are coelomates, which means that their body cavity is fully lined with the mesoderm.
if Kevin Washington is correct it is coleomate
The type of body plan a Dugesia has is an acoelomate body. This elongated body lacks internal structures for holding internal organs.

Vertebrates hae bony internal skeletons.
Humans, like all mammals and other vertebrates, have bilateral symmetry. This means they have 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.
Hox genes play a critical role in determining the body plan of vertebrates, influencing the development of structures along the anterior-posterior axis. Disruptions in Hox gene expression can lead to severe abnormalities in body structure and function. They are fundamental in specifying positional information during embryonic development in vertebrates.
All vertebrates display bilateral symmetry.

Mammals and most vertebrates have a closed circulatory system in which the blood stays in the blood vessels and recirculates. In an open circulatory system the hemolymph is pumped out by the heart, but perfuses the entire body cavity.
Jaguars are mammals and therefore vertebrates, and all vertebrates have bilateral symmetry. This means they have 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.
Anteaters are mammals; mammals are vertebrates, and all vertebrates have bilateral symmetry. This means they have 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.
