Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Farinacci & Howe Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly compiled on this site. The "Catalogue of Calcareous Nannofossils" was originally compiled by Prof A. Farinacci 1969-1989, since 2000 it has been updated and extended by Richard Howe - see The Farinacci and Howe Catalog - an Introduction.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

Original Description Motile cells sphaeroidal to ovoid with a flattened flagellar pole and the opposite pole slightly tapering, some metaboly, 3-5 (exceptionally 2.5-7.5) µm in diameter. Two equal homodynamic flagella, 2-3 times the cell diameter in length, with a distinct knobbed mucronate tip more than twice the flagellar diameter in length visible with the electron microscope. One haptonema slightly shorter than theflagellawhen fully extended, arising with them at the flattened cell pole. Periplast covered by very thin sculptured scales, nearly circular to ellipsoid, sometimes hexagonal to octagonal, 0.2 x 0.3 to 0.5 x 0.7 µm in size. Cells uninucleate, no stigma. Chromatophores usually 1 or 2, sometimes 4, 8 or none, deep golden-brown, in motile phase saucer-shaped, parietal, with medium sized globular body (pyrenoid ?) on inner face placed near the margin nearest the flagellar pole; in non-motile phase deeply lobed or stellate. Oil and leucosin produced. Muciferpus bodies localized near the non-flagellar pole. Nutrition holophytic and/or phagotrophic. Non-toxic to fish. Asexual reproduction of pigmented and non-pigmented forms in motile phase by fission into 2 or 4 daughter-cells; in non-motile phase by fission of amoeboid cells to produce 4 walled daughter-cells which probably liberate motile phase.
