2006Botanical Garden in AobayamaVIII
Soils from the L, H, and A layers were sampled from the Tohoku University Botanical Garden in Sendai. This is a video of an organism taken from the A layer, the first layer below the soil surface (which is composed of L, F, and H layers). The A layer is mainly composed of mineral particles and humus. At first organisms could not be found in the newly collected soil, so the samples (including water) were left for one month and then observed.
Commentary by Prof. Yuji Tsukii, Hosei University
This flagellate may be genus Cercomonas or a relatad genera. It has two frontal flagella, one that extends forward while the other trails backward, which is characteristic of Cercomonas.
There are two types of Cercomonas that I have observed: (1) the entire rear end moves like an amoeba; (2) the tip of the rear end stretches out behind the cell like a flexible tail as the cell moves around.
