Rhizosolenia (rye-so-so-lean-ee-a) setigera, one of the common genera of marine phytoplantkonic diatoms, a centric diatom in which the valves, at the ends of the cells, are conical and give rise to spines. Much of the long cylindrical body is enclosed with hoop-shaped girdle bands. Phase contrast microscopy.

Valvar view. Insets showing marginal ring of labiate processes (upper right) and the hyaline central area (lower left). Scale bar indicates 100 µm. Sample from North Sea near Heligoland (spring diatom bloom). The image was built up using several photomicrographic frames with manual stacking and stitching technique. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.
