A diatom from a paddy field
The sample was observed immediately after being collected.
A large diatom is going in and out of soil aggregates. Small particles are moving inside of the diatom cell, and also a small unknown organism is moving behind it.
Commentary by Prof. Yuji Tsukii, Hosei University
This diatom belongs to genus Surirella, probably Surirella robusta. It is often found in rivers.
