WebBiradial Symmetry: The body of animals which exhibits biradial symmetry, represents a combination of both radial and bilateral symmetry. The organs are arranged radially and the body can be divided into two by a mid-longitudinal plane. Ctenophores exhibit biradial symmetry. Type # 5. Bilateral Symmetry: WebExternal symmetry allowed our aquatic ancestors to become streamlined for speed [1672, 1871, 2766], and it has been retained ever since because it is just as useful for walking as it was for swimming [517]. In contrast, the only locomotory restriction on our internal organs has been that their weight be distributed evenly relative to the midline.
