Bilateral symmetry in animals exhibits mirror image division with distinct features like anterior and posterior ends and right and left sides, promoting streamlined motion and active resource-seeking behaviors.
Bilateral symmetry involves the division of animals through a midsagittal plane, creating mirror images on the right and left sides, such as in butterflies, crabs, and humans. Animals with bilateral symmetry exhibit features like anterior and posterior ends, defined dorsal and ventral surfaces, and right and left sides. This symmetry allows for streamlined motion, directional mobility, and is associated with active resource-seeking behaviors in animal evolution.
