Diatom from a paddy field

The sample was observed immediately after being collected from a paddy field.

A diatom cell is slowly threading its way through obstacles.


Commentary by Prof. Yuji Tsukii, Hosei University
This diatom belongs to genus Pinnularia. When it glides on a surface, it usually shows the top view, called the valve face. However in this video, it shows the side view, called the girdle face. When the organism encounters particles in its path, it rolls onto its side to get through them.
