Radial symmetry
Radial Symmetry
Radial symmetry (pronunciation: /ˈreɪdiəl ˈsɪmɪtri/) is a type of symmetry where an organism or object can be divided into similar halves by more than two planes passing through the center. This type of symmetry is common in many biological organisms, particularly those that are sessile or planktonic.
Etymology
The term "radial symmetry" is derived from the Latin radius, meaning "ray", and the Greek symmetria, meaning "measure together". This reflects the characteristic of radial symmetry where all parts radiate out from a central point.
