Magnification of all photos: 1000× (oil immersion)
Habitat: planktonic algae from the edge of a large freshwater pond.
Using stage micrometer for calibration, individual cells estimated to be about 36 µm from tip to tip.

On the sidewalk, apparently stunned after flying into a window at Emerald Plaza library.
Tiny and fast. I thought it was a fancy ant before I got the photo.
Each cell measures 2 µm in diameter
Site of sample collection: Pavilion, North Pond, Katsurashima Ryokuchi (a freshwater habitat), Sendai, Japan
Date of sample collection: September 21st, 2024

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.
