Eucampia (you-camp-ee-a) zoodiacus is a filament forming diatom (stramenochrome). Adjacent cells are attached by two interlocking apical elevations. Differential interference microscopy.

Odontella (owe-don-tell-a) mobiliensis, a centric diatom. The frustule or shell is formed of two valves joined by girdle bands. With horns (spines) emerging from the apical margins of the valves and more spines (referred to as apical processes) arising closer to the centre of the valves. Many small peripheral chloroplasts and a central nucleus. Two daughter cells located within frustule of parental cell. Differential interference microscopy.
data on this strain.
-
After several minutes of observation chloroplasts are transported to the cell center, maybe to save the nucleus and most of the chloroplasts against harmful amounts of UV radiation. The image was built up using several photomicrographic frames with manual stacking technique. Scale bar indicates 50 µm. Sample from North Sea near Heligoland (spring diatom bloom). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.

Cells are single or united into short chains by the long spines extending from the elevated central part of the valve face. The processes are slender and point diagonally outward. This species can be confused with O. regia.
