Description

[Only one cell observed.] Cell spherical, 2 µm diameter. Flagella c. 12 µm long. Body scales of 1 type: plate scales sparse, circular, 0.5–0.7 µm diameter, with 12–14 fine radiating striae on one (?distal) surface.

Distribution

Southern Ocean, south of Australia, 52.01°S 134.05°E.

Comments

The body scales of the single specimen collected resemble C. mantoniae B.Leadb. from Tasmania (LeRoi & Hallegraeff, 2004), but the haptonema is considerably longer than the 10 µm reported for C. mantoniae. The latter species also bears long spine scales at the anterior and posterior ends of the obovate cell body.

Chrysochromulina genus description: Cells have homodynamic flagella and a coiling haptonema, and electron microscopy is usually required to identify the species. As well as being photosynthetic, these fragile haptophytes ingest picoplanktonic and nanoplanktonic organisms by phagocytosis.
