O. sinensis is closely related to O. mobiliensis and O. regia but the processes are nearly parallel to the cell axis and the processes are close to the processes. The valve face between the processes is flat or concave.

Depth-of-focus image exhibiting structure of the frustules. Chloroplasts are concentrated in cell centers due to long lasting exposition with microscope's illumination. Scale bar indicates 25 m. The image was built up using several photomicrographic frames with manual stacking technique. Sample from North Sea near Heligoland (spring diatom bloom). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.For more look at

Triceratium moronense.
-
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.
