A tiny round organism

The sample was observed immediately after being collected. While clinging to soil aggregates, this round greenish organism is continually moving. Such a strange organism is often observed in the microbial world.

Commentary by Prof. Yuji Tsukii, Hosei University
This organism cannot be identified at all. The green color suggests that it contains chlorophyll. It moves despite sticking to aggregates but we cannot determine how it moves.
