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 Amoeba:
Locomotive cells, often 220 to 760 µm in length, although A. diminutiva Bovee, 1972 is only 15 to 20 µm. Usually polypodial with one dominant cylindrical pseudopodium, often with ectoplasmic ridges. Resting, or well fed, cells irregularly rounded. Floating form with long, radiating pseudopodia. Cytoplasm granular in appearance often with truncated bipyramidal crystals. Posterior uroid morulate when present. Single nucleus, discoid or ovoidal, sometimes with peripheral granules. Nucleolar material often scattered. At the ultrastructural level, surface coat of A. proteus has filaments rising 230 nm above the plasma membrane whereas coat of A. lenigradensis amorphous and without filaments. Freshwater. The genus is best known for the species A. proteus which is a popular teaching tool and familiar to most students of biology.
