Welcome to Bio*Pedia!

Bio*Pedia is a repository of descriptions of organisms and a partner of the Encyclopedia of Life (EOL). Descriptions added to Bio*Pedia will be harvested at regular intervals, and will appear on EOL species pages.1

Want to contribute a text description for an EOL species page now? Here are a few easy steps to get started:

  • Please register with Bio*Pedia or login if you are already registered (Bio*Pedia has a separate registration system from EOL).
  • If you are not registered yet, please fill in all fields in the registration form. You will receive an e-mail with a registration confirmation link shortly. After you click this link, you can begin contributing to Bio*Pedia and EOL.
  • Type the scientific name of the species that you wish to add a description to (without author and year) into the search box, select and jump to the species name, and click on the "Add description" link in the upper left corner of the page. Type your description into the lower (yellow) box, choose the appropriate license, click "Save description", and your description will immediately appear in Bio*Pedia, which means that it is on the way to EOL!1

1Please note that your description will not appear immediately on EOL Species Pages. If submitted descriptions are deemed inappropriate or inaccurate, they may not be included in EOL.

Description of Paramyxea:
Circumscription: Parasitic heterotrophic protists typically found in the digestive system of marine invertebrates where they feed by osmotrophy. Initial infectious cell is amoeboid. Paramyxeids are regarded as multicellular because the daughter cells formed by division of the infectious cell may be contained within the initial cell; these continue to develop into multicellular spores. With a complex process of nuclear and cellular division. Ultrastructural identity: Shape of mitochondria not confirmed. With a reduced (nine single microtubules) centriolar structure associated with the microtubules of the mitotic spindle; nuclear envelope disrupts during division. Synapomorphy: Tubulocristate protists, during spore development endogenous budding accompanies cell division. Composition: Several genera. Ref: Desportes and Perkins 1990.
