| Heliophrya rotunda the focus plane is on the tentacles that are distributed in fascicles which are orientated like the scale marks of a clock. Some diatoms have been caught by the tentacles. Interestingly enough the specimens shown in these images were found on artificilally exposed micro-slides, the same subtrate as described in the book of D. Mattes about Suctoria. The oval-shaped macronucleus with the micronucleus (on the right) is visible in the center of the cell. (1) |
