Euglenas attached to each other

Two single-celled flagellates, called Euglena, have become stuck on a solid surface and cannot move. When another Euglena joins them, it attaches itself to the first pair and stops moving as well. Meanwhile, various kinds of flagellates and ciliates are passing nearby.

Commentary by Prof. Yuji Tsukii, Hosei University
The organism in the first scene is certainly Euglena viridis.
