  • Radiolaria - Wikipedia
    The Radiolaria, also called Radiozoa and informally called radiolarians, are unicellular eukaryotes of diameter 0 1–0 2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm
  • Radiolaria — Wikipédia
    Les Radiolaires (Radiolaria), également appelés radiozoaires, sont un embranchement d' Eucaryotes unicellulaires hétérotrophes qui produisent des squelettes minéraux complexes, généralement avec une capsule centrale divisant la cellule en une partie interne et une partie externe
  • Radiolarians - Incredible Microplankton | MarineBio
    Radiolarians are single-celled eukaryotic marine organisms known for their intricate mineral skeletons and important ecological and geological roles in the oceans
  • Radiolaria. org

  • Radiolaria. org gt; What are radiolarians
    Radiolarians are part of the marine plankton They occur in all oceans, including shallow seas, bays, fjords, etc , but almost invariably at salinities above 30 parts per thousand (slightly lower than normal marine values)
  • Radiolaria - Geology is the Way

  • Radiolaria - UCL
    Radiolaria are holoplanktonic protozoa and form part of the zooplankton, they are non-motile (except when flagella-bearing reproductive swarmers are produced) but contain buoyancy enhancing structures; they may be solitary or colonial Formally they belong to the Phyllum Protista, Subphylum Sarcodina, Class Actinopoda, Subclass Radiolaria

  • Introduction to the Radiolaria - University of California Museum of . . .
    Radiolaria can range anywhere from 30 microns to 2 mm in diameter Their skeletons tend to have arm-like extensions that resemble spikes, which are used both to increase surface area for buoyancy and to capture prey Most radiolarians are planktonic, and get around by coasting along ocean currents
  • Radiolaria - New World Encyclopedia
    Radiolaria is a diverse grouping of amoeboid protozoa that produce intricate mineral skeletons, typically with a central capsule of cytoplasm separating the cell into inner and outer cytoplasmic portions, called endoplasm (with nuclei) and ectoplasm (or extracapsulum)
