Detailed explanation-1: -Bilaterally symmetrical animals have a dorsal side (top), a ventral side (bottom) and distinct left and right sides. They also have an anterior side (head), and a posterior side (tail), and exhibit cephalization.

Detailed explanation-2: -Animals possessing bilateral symmetry have a dorsal (top) side, a ventral (bottom ) side, an anterior (head) end, a posterior (tail) end, and a distinct left and right side.

Detailed explanation-3: -Most animal phyla have bilaterial symmetry. Examples of bilaterally symmetrical animals include worms, insects, and molluscs. These organisms will typically have a front end known as the anterior and a back end known as the posterior. They also have left and right sides that mirror each other.

Detailed explanation-4: -Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.

Detailed explanation-5: -A condition in which the right and left sides of an item (e.g., a shape or an animal) are mirror images of one another. For example, since the right side of the human body generally mirrors the left side, humans are bilaterally symmetric.
