Two diatom cells adhereing together

After being collected from a paddy field, the sample was put on 1% agar plate with a drop of distilled water and kept for two days. Two slender diatom cells are connected, perhaps after dividing, and are gliding around together.

Commentary by Prof. Yuji Tsukii, Hosei University
Two diatom cells are connected side by side. Both cells show the girdle faces and only the right cell shows the valve face, from the latter the organism is assumed to be Pinnuralia.

Probably the two Pinnularia cells have not separated after division.
