Most animals will have a high level of right to left symmetry, or "Reflection Symmetry". Note, the symmetry isn't perfect as many of the internal organs only have a single organ and are arranged in a non-symmetric fashion.
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
