| 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. |
