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.

Original Description

Motile cells sphaeroidal to pyriform with flagellar pole usually flattened; metaboly of body well-marked particularly at non-flagellar pole; cells 4-7 mm (exceptionally 3.5-11.5 µm) in length or diameter. Two equal, homodynamic, shortly mucronate flagella, 2½-3½ times cell diameter in length and one haptonema, 2-2½ times cell diameter in length when fully extended, arising close together at flattened pole. Periplast covered by very thin sculptured ellipsoid scales, approximately 0.7µm. across, each with a central spine attached by four decurrent ridges, spine length approximately equal to scale diameter.

Cells uninucleate, no stigma. Chromatophores usually 2 or 4, occasionally 1 or 8, golden brown; in motile phase saucer-shaped, ellipsoid or oblong, parietal with small globular body (pyrenoid ?) on inner face of each near the margin towards the non-flagellar pole; in non-motile phase deeply lobed or stellate. Oil and leucosin produced. Muciferous bodies conspicuous, usually inrows,buttheirpositionchangingwiththemetabolyofthebody. Nutrition holophytic and/or phagotrophic. Not toxic to fish.

In motile phase asexual reproduction 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.

Size:
Cells 4-7 mm (exceptionally 3.5-11.5 µm); scales very thin sculptured ellipsoid, approximately 0.7µm
