WEBOct 26, 2017 · Bilateral symmetry is the arrangement of an organism's body parts into left and right halves on either side of a central axis, or plane. Essentially, if you draw a line from the head to the tail of an organism -- or a plane -- both sides are mirror images. In that case, the organism exhibits bilateral symmetry.
