Extended Observation Description on Platycola longicollis

Platycola longicollis on Moss Filaments (Drepanocladus aduncus) from a Freshwater Aquarium

First observation

Platycola longicollis
Fig. 1: Platycola longicollis on a moss filament (Drepanocladus aduncus); image taken using a dissecting microscope. Length of the lorica appr. 100 µm.
Platycola longicollis

Fig. 2: A closer look on Platycola longicollis. Objective 20x.
Scale bar indicates 50 µm.

Platycola longicollis

Fig. 3: Another lorica with two cells of Platycola longicollis. Optical section through the cells. Objective 40x oil immersion.
Scale bar indicates 25 µm.

Platycola longicollis

Fig. 4: The second optical section through the lorica shows the shape of the opening typical for this species. Objective 40x oil immersion.
Scale bar indicates 25 µm.

Platycola longicollis

Fig. 5: Complete lorica, mounted on the moss stem with its long side in the direction of view. Objective 40x oil immersion.
Scale bar indicates 25 µm.

Second observation

Platycola longicollis

Fig. 6: Optical section through the cell and the lorica showing the worm-shaped macronucleus traversing almost the entire cell (arrows). The brightly glowing dots are mitochondria. Objective 40x water immersion.
Scale bar indicates 50 µm.

Platycola longicollis

Fig. 7: The sectional plane is placed in such a way that the striation on the cell body is partially shown (arrow). In order to be able to see this detail well, the page must be displayed at 200%. Objective 40x water immersion.
Scale bar indicates 50 µm.

Platycola longicollis

Fig. 8: Representation of the complete lorica, it was exactly perpendicular to the direction of observation. Objective 40x water immersion.
Scale bar indicates 50 µm.

Platycola longicollis

Fig. 9: Two optical sections through the Lorica mounted on a moss trunk with the long side facing the viewer. The neck and opening of the bottle are detailed. Objective 40x oil immersion.
Scale bar indicates 50 µm.
