Sorry, no etymologies found.


  • When studying the chromosomes of Tetrahymena, a unicellular ciliate organism, she identified a DNA sequence that was repeated several times at the ends of the chromosomes.

    The 2009 Nobel Prize in Physiology or Medicine - Press Release

  • A beautiful example of this paradigm is a single cell organism called ciliate – the gene assembly process in ciliates has turned out to be a very elegant computational process which even uses one of the basic data structures of computer science: the linked lists!

    De Facto Intelligent Design in Biology

  • As these cells are small (about a micrometer across) the most likely consumers of Synechococcus or Prochlorococcus are flagellate and ciliate protists.

    Marine microbes

  • Similarly, among protists, a radiolarian may capture and ingest, more or less indifferently, a bacterium, an autotrophic flagellate, a herbivorous oligotrich ciliate, or another radiolarian (Fig 2E).

    Marine microbes

  • The ciliate herbivores are then fed upon by larger organisms such as copepods (small crustaceans).

    Marine microbes

  • In higher light conditions these algae convert the carbon dioxide produced by the ciliate into oxygen, ensuring an abundant internal supply of oxygen for the ciliate.


  • These were almost always due to the dinoflagellate Gonyaulax, and sometimes to the ciliate Mesodinium.

    Iberian Coastal large marine ecosystem

  • The data are publicly available to test the hypothesis at ciliate. org.

    Another Protozoan and Front-Loading

  • Researchers working with the ciliate Paramecium have discovered that protozoans have a very high mortality rate after conjugation.


  • Sessile forms (e.g. Suctioria) use haptocysts on feeding tentacles to snag smaller ciliate prey and then suck out the nutritious cytoplasm.
