NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Animals with bilateral symmetry have a “head” and “tail” (anterior vs. posterior), front and back (dorsal vs. ventral), and right and left sides. All true animals, except those with radial symmetry, are bilaterally symmetrical.

Detailed explanation-3: -When the body plan of an animal can be divided along a line that separates the animal’s body into right and left halves that are nearly identical of each other, it is said to have bilateral symmetry.

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