A Chilodonella ciliate
The front of this ciliate, Chilodonella, is slightly bent and flexibly changes shape when it touches an obstacle. The shape of its body resembles a kidney bean, but we cannot recognize its characteristics in detail because the organism keeps disappearing behind particles.
Commentary by Prof. Yuji Tsukii, Hosei University
This organism belongs to genus Chilodonella.
It may be Chilodonella cucullulus, but we can’t be sure.
