symmetry

 [sim´ĕ-tre]
correspondence in size, form, and arrangement of parts on opposite sides of a plane, or around an axis. adj., adj symmet´rical.
bilateral symmetry the configuration of an irregularly shaped body (such as the human body or that of higher animals) that can be divided by a longitudinal plane into halves that are mirror images of each other.
radial symmetry that in which the body parts are arranged regularly around a central axis.

radial symmetry

n.
Symmetrical arrangement of constituents, especially of radiating parts, about a central point.
radially symmetrical adj.

radial symmetry

a form of symmetry in which body parts are arranged around a central axis, as found in animals such as jellyfish and sea urchins.

radial symmetry

an animal body structure in which any section through the mouth and down the body length divides the body into identical halves. Coelenterates, ctenophores (sea gooseberries) and echinoderms are all radially symmetrical. Compare BILATERAL SYMMETRY.
