Cell size: 4-5 µm in length, 2.5 µm in width
Site of sample collection: Pavilion, Takamori Higashi Park (a freshwater habitat), Sendai, Japan
Date of sample collection: Aug. 8th, 2021
Weather: Rainy
Water temp.: 29.0°C
pH 6.6
Date of observation: September 12th, 2021 (the collected sample in a plastic container was left near a window out of direct sunlight at room temperature until observation)
Bright-field observation using a Wraymer microscope (model BX-3500TL, Osaka, Japan) equipped with a Floyd-2 HDMI ethernet digital camera (Wraymer, Osaka, Japan). The accuracy of the scale bar was confirmed by using a stage micrometer glass slide (1 div. = 10 µm; Wraymer, Osaka, Japan) at each magnification.
