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 Euplotes:
An iInflexible hypotrich, dorso-ventrally flattened, dorsally ridged, oval body with very large AZM usually extending at least two-thirds the body length. Common in freshwater and marine habitats. Marginal rows of cirri absent but usually there are 1 or 2 weak cirri on the left margin. There may be a lateral ciliary row on either side of the ventral surface. Large fronto-ventral and transverse cirri present. With 2-3 large (right) caudal cirri. Macronucleus C-, M- or horseshoe-shaped, with single adjacent micronucleus. First described by Ehrenberg (1831). Many species. One of the main morphological traits used for carrying out a preliminary species distinction is the type of argyrome shown by the cell on its dorsal surface. This term refers to the geometrical, meshwork-like structure which becomes apparent after the cell is silver-stained, and reflects lines of junction between the flat, polygonal alveoli. A division of Euplotes species into groups is often made on the basis of three basic argyrome types, each defined by the number of rows of polygons lying between any two adjacent kineties.There may be one, two, or more than two of these rows - allowing patterns to be classified as single, double, or multiple types.The double argyrome type typifies eurystomus and patella. The number and disposition of the ventral cirri and the geometry of the dorsal argyrome, have been regarded as being sufficiently clear and stable to justify some workers splitting this taxon into four morphologically distinct sub-genera, Euplotes, Euplotoides, Euplotopsis and Monoeuplotes
