Microbes among particles
First we see a small ciliate, Aspidisca, passing through a space surrounded by particles. Then a large slender ciliate appears and begins to look for food. We can see a small ciliate in the process of division beside one of the particles.
Commentary by Prof. Yuji Tsukii, Hosei University
The organism approaching from the lower right may be Aspidisca cicada (previously called Aspidisca costata).
The dividing cell hiding itself behind a black particle is Cinetochilum margaritaceum.
After Aspidisca disappears, Uroleptus appears from the lower rightside.
