Such exploration requires ARTICLE IN PRESS radiolarians in the Phanerozoic is conducted based on the informational system "RADBASE" containing the information on 1721 genera of radiolarians and their synonyms. Problems of the biology, ecology, and taphonomy of radiolarians are discussed. It is shown that the biomass of polycystine radiolarians is greatest at depths of 50--400 m. The broad range of prey accepted by many of the radiolarians studied thus far suggests that they are opportunistic feeders and are capable of adapting to a broad range of trophic conditions. The role of algal symbionts, when present, has been debated for some time—beginning with their discovery in the mid-19th century.

Radiolaria are protozoa distinguished 1) by segregation of their soft anatomy into the central capsule, containing the endoplasm, and the surrounding ectoplasm (or calymma), and 2) by their siliceous (opaline) skeletons of the large majority of species. But the ecology of radiolarians is pretty much uncharted territory, we don’t even know if they have any natural enemies. So there is a lot of interesting science just waiting to happen." "Radiolarians have been around for hundreds of millions of years, and it is a safe bet to predict that they are going to outlive us humans by a wide margin. Radiolarians ecological role. Parasite and consumer. Cercozoans ecological role.

Processes taking place in this environment play a signiﬁcant role in the sequestration of organic carbon, and thus for global climate development.

The siliceous skeletons of radiolarians settle into the ocean sediments where they form a stable and substantial fossil record. These microfossils are an important source of data in biostratigraphic and paleoclimatic studies. Considering their habitats, radiolarians represent a promising tool to explore the mesopelagic environ-ment in the geological past. Processes taking place in this environment play a signiﬁcant role in the sequestration of organic carbon, and thus for global climate development.
