A small amoeba squeezing between small particles

A transparent small amoeba changes it shape to squeeze into a particle. A tiny flagellate and diatoms are swimming around the edges of the screen.

Commentary by Prof. Yuji Tsukii, Hosei University
This organism is certainly a naked amoebae (without shell), but, it cannot be identified because its whole shape and especially the shape of its rear end cannot be seen clearly.
