A round green organism

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

In this green spherical organism, the cytoplasm with a red spot is slowly rotating. Is this organism Euglena?

Commentary by Prof. Yuji Tsukii, Hosei University
It cannot be determined exactly what this organism is. However, the cytoplasm is continually moving inside of a transparent round shell, and we can see green particles that seem to be protoplasts and a reddish spot in the cytoplasm. Therefore it might be Euglena in a dormant state.

Sampling Date : 18 July 2006
