radial symmetry

Symmetrical arrangement of constituents, especially of radiating parts, about a central point.

radially symmetrical adj.

radial symmetry

(Biology) a type of structure of an organism or part of an organism in which a vertical cut through the axis in any of two or more planes produces two halves that are mirror images of each other. Compare bilateral symmetry

ra′dial sym′metry

a basic body plan in which the organism can be divided into similar halves by passing a plane at any angle along a central axis. Compare bilateral symmetry.

ra·di·al symmetry

The arrangement of similar forms or features around a central point. The bodies of echinoderms, such as starfish and sea urchins, are radially symmetrical. Compare bilateral symmetry.

However, the consistent organization of this type of motor control system in a wide variety of extant species argues that it also represents an efficient means of achieving the unique problem of non-polarized control of a broad two-dimensional sheet of effectors, and thus is more a consequence of the radial symmetry and a need to sense the environment from multiple sites spatially arranged around the margin of the bell.
