  • 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
  • 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
  • 放射虫_百度百科
    放射虫软泥，主要分布于热带太平洋和印度洋深海底。 与放射虫骨骼本身的结构有关，骨骼纤细的种类更易溶解。 放射虫主要靠伪足捕食各种浮游生物。 放射虫共生的藻类（虫黄藻）也可为放射虫提供营养。
  • 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. org
    Radiolaria are holoplanktonic protozoa widely distributed in the oceans They occur throughout the water column from near surface to hundreds of meters depth
  • 放射蟲 - 维基百科，自由的百科全书
    放射虫門 （學名： Radiozoa）又名 放線蟲，為海中浮游生物，有如球形對稱，帶有矽殼，殼上有美麗的花紋。 身体内有膜质中央囊，囊面穿有许多小孔，将身体分为内外两部分，外部被胶状物质，多有 液泡，内部有 细胞核 、液泡和赤、黄等色的油滴；通常均由身体中央射出针状骨棘，间或多数针状物相集成层或互相连络而成笼状，形状精细繁多；多以分裂法繁殖，也有以孢子繁殖的。 放射虫多产于热带海洋中，因為迅速的繁殖與過多的物種，是診斷化石的重要依據，可從 寒武紀 開始。 放射蟲有很多針狀偽足的支援，即所謂軸足（axopods），可承受放射蟲的浮力。 11 Discoidea 21 Acanthometra 22 Spyroidea 31 Cyrtoidea 41
  • Radiolarian - an overview | ScienceDirect Topics
    Radiolarians are silica-secreting, single-celled protists that dwell in open-ocean locations They occur throughout the water column from near surface to great depths
  • Introduction to the Radiolaria
    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 - 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)
