ecology: |
|
Cephalodella gibba, is obviously a predator of other rotifers: the arrowheads mark the trophi of a dicranophorid rotifer (Encentrum sp.) that has been engulfed by this specimen from (6) |
|
|
Encentrum sp., image of the above diet; after the predator had been treated with NaOCl for maceration of the trophi this specimen was rinsed with water and could then be photographed. |

Cephalodella gibba, two images of a specimen from (7), which is heavily infested by fungal parasites (upper image; arrowheads) . Also faintly visible are the virgate trophi of an engulfed rotifer of the same genus: Cephalodella. After maceration it turns out that the trophi (see lower image, arrow) are of type A, which fits to C. exigua which was also found in the same sample. |
