Radiolaria are protozoa distinguished by the segregation of their soft anatomy into a central capsule, and their siliceous tests which often have many spines extending outward. Radiolarians have existed since the beginning of the Paleozoic era, producing an astonishing diversity of intricate shapes during their 600 million year history. There are two superorders, Polycystina and Phaeodoria.
