In spite of having a long body, this ciliate is flat like a ribbon. The organism is thus able to move delicately through the narrow spaces between particles.
Commentary by Prof. Yuji Tsukii, Hosei University
This ciliate may belong to either genus Loxodes or genus Remanella.
These groups look similar and are distinguished mainly by the following points: (i) the presence or absence of a fibrous structure in the cytoplasm, and (ii) the structure of the mouth area. Since these characteristics cannot be seen clearly in this video, it is difficult to determine to which genus this ciliate belongs.
