Description

[Only scales observed.] Body scales of 4 types: large spine scales, with the spine tapered, supported basally by 4 struts 1.4 µm long, attached to base-plate, overall length to 15 µm, base-plate upwardly flexed, distal surface with fine radiating striae; small spine scales similar in structure to large spine scales, but overall length 0.6–1.6 µm, distal surface with 80–100 fine radiating striae; large outer plate scales, flat, circular to elliptical, c. 2 µm diameter, with a faint rim, distal surface patterned with c. 110 fine radiating striae; underlayer of small elliptical plate scales 0.5 × 0.8 µm, with a narrow raised rim, proximal surface with a faint patterning of radial striae, distal surface patternless.

Distribution

Southern Ocean, Pacific sector, 54°30.4’S 158°47.0’E.

Comments

This material closely resembles C. vexillifera. See discussion under Chrysochromulina type A.

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.
