Biradial symmetry

Neal stephenson seveneves audiobook

An animal with radial symmetry could be divided into equal portions from the center, in the same way that you could cut a pie into wedges. An animal with radial symmetry really has no right and left side or head and rear end. Radial symmetry is ideal for animals that do not move, so they can reach into their environment on all sides.

The symmetry properties of bilaterally symmetrical larval and adult metazoans are generally set up during the cleavage period while most “radially” symmetrical cnidarians do not display a stereotyped cleavage program. Ctenophores display biradial symmetry and may represent one intermediate form in the transition to bilateral symmetry. Biradial definition: showing both bilateral and radial symmetry , as certain sea anemones | Meaning, pronunciation, translations and examples biradial - showing both bilateral and radial symmetry; "some sea anemones are biradial" symmetric , symmetrical - having similarity in size, shape, and relative position of corresponding parts Want to thank TFD for its existence?

The Porifera and Placozoa tend to be asymmetrical (lack anterior-posterior and left-right symmetry), the Cnidaria generally have radial or biradial symmetry, and the Ctenophora are typically biradially symmetrical. Phylum Chordata Basically, the idea is that bilateral symmetry is the default, and deviations are the result of either undesirable mutations or environmental effects, so organisms look for it when selecting mates. Most of the literature concerns animals (often arthropods), which may be how it slipped you by.

A variant of radial symmetry is known as biradial symmetry, in which the body can be divided two equal symmetrical halves through only two plane passing through oral-aboral axis; e.g. Ctenophores and sea anemones. The cnidarians and ctenophores both with primary radial symmetry are together grouped as Radiata. The blue ridiculosity shows 'biradial symmetry'. You might think it has bilateral symmetry, but it doesn't: there still is no front or rear, nor left and right, to this beast. Rather than right it seems to be wrong. Still, believe it or not, 'biradial symmetry' exists! Just check Wikipedia. But do not expect anything with legs as shown here...
