Two ciliates: big and small

A small ciliate with cirri at the front and the rear is foraging among particles. Then a giant ciliate about four times larger appears, but it soon turns and swims away.

Commentary by Prof. Yuji Tsukii, Hosei University
The smaller organism is Balladyna, and the larger one is Remanella.
