| Two images of a resting egg of a monogonont rotifer. It was found in the same sample and may be a resting egg of C. tenuior. In the optical transect of the upper image the egg may be confused with the resting egg of Polyarthra, but by focusing on the surface (lower image) it becomes evident that it is no Polyarthra egg. |

 |
