Euglena oxyuris - 2nd image added

Post by NikonUser »

A large cylindrical species almost always twisted (about 2/3 rds down in this one), with a large number of green plastids, large central oval nucleus and large red eyespot. Pellicle wth longitudinal ridges. Very slow moving (sluggish) but fast enough to disallow stacking.
This individual 360µ long.
20x SPlan Apo + 2.5x relay lens (NFK); almost full frame, single frame, flash.

The earlier image was of a this specimen in a depth of water that allowed it to exhibit its normal twisted shape.
As the water dried out beneath the coverslip the water became shallower and the specimen became a little flatter:
