What is animal symmetry and how is it described?

Animal symmetry refers to the harmonious arrangement of body parts around a central axis. It is commonly classified into three types: bilateral symmetry, where the body can be divided into mirrored halves along one plane; radial symmetry, which allows for multiple planes of symmetry radiating from a central point; and asymmetry, where no symmetrical arrangement exists. This classification helps in understanding the evolutionary relationships and functional adaptations of different animal species.
