    Radiolarians are unicellular predatory protists encased in elaborate globular shells (or "capsules"), usually made of silica and pierced with holes Their name comes from the Latin for "radius"
  • Radiolarian | Marine Protists, Plankton, Microscopic | Britannica
    radiolarian, any protozoan of the class Polycystinea (superclass Actinopoda), found in the upper layers of all oceans Radiolarians, which are mostly spherically symmetrical, are known for their complex and beautifully sculptured, though minute, skeletons, referred to as tests
  • Radiolaria - Geology is the Way
    Radiolarians are single-celled protozoa, measuring less than 0 1 – 0 2 mm in diameter, that produce intricate shells (skeletons) of amorphous silica They float as part of the zooplankton in the first 200 meters of water in the Earth’s oceans (photic zone)
  • Radiolarians: Microscopic Marine Mysteries | AMNH
    Radiolarians, single-celled marine organisms with intricate silica skeletons, have existed for at least 550 million years and are found in all the world’s oceans
  • Radiolarian - an overview | ScienceDirect Topics
    Radiolarians are small marine organisms that graze on phytoplankton and organic detritus in oceans They have intricate siliceous shells, with the polycystine radiolarians being the ones that fossilize well and are commonly used in paleontological studies
