Twins from a paddy field?
After being collected from a paddy field, the sample was put on 1% agar plate with a drop of distilled water and kept for two days. Two cells are connected, perhaps after dividing. As the organism moves quickly and unpredictably, thorough observation is impossible.
Commentary by Prof. Yuji Tsukii, Hosei University
This organism may be Coleps in the process of division. After the division is completed , the two cells of Coleps remain connected for a while and continue to move around together. Prominent ectoplasmic plates normally cover the cell surface of Coleps, but immediately after cell division, the surface of the two daughter cells are partly without the plate. This characteristic of a temporarily missing plate can be seen at the very beginning of the video.
