The other day, in a session with the ” Dutch Microscopical Society (NGVM) ” we’ve been introduced to work with fructose as a mountant for plankton and other objects containing water.
The sample taken from a nearby ditch turned out to contain a huge amount of Euglena in different species.
With 25x and 40x objectives and differential interference contrast I’ve attempted to capture their details. The red pigmented spot above the “eye” got lost after preparation, though the outer structure can been seen.
In addition to that an embryonic ostracod was spotted. The last photo shows what looks like a part of the structure of a waterlily stem surrounded by euglena.
