| Bdelloid 20; dorsoventral view of whirling specimen. This morphotype is characterized by a wide corona with wide sulcus. Also visible is the layer of grained substance (??detritus??) on the dorsal integument of the trunk. (1) |

 |
| Bdelloid 20; dorsoventral view of another creeping specimen showing that the rostrum is distinct from the head (2) |
| |
 |
| Bdelloid 20; lateral view of creeping specimen. This image demonstrates that only the dorsal integument is covered with grains: the grain-covered integument looks somewhat like the saddle of a horse (2) |

 |
| Bdelloid 20; lateral view of another specimen. Focus plane on the conspicuous dorsal antenna. (1) |

 |
| Bdelloid 20; two aspects of a creeping specimen in ventral view. Focus plane on the ?toes?/ ?adhesive disc? (left) and the rostrum lamella (right) (2) |
| |
  |
| Bdelloid 20; left: dorsal view of foot with tapering spurs and interspace. The innner side of the spurs is bent outwards, while the outer side is straight. Right: ventral view; unfortunately it was not possible to find out the number of toes or if there is an adhesive disc. (1) |

  |
| Bdelloid 20; dorsal view of foot of specimen from (2). Upper images: foot in the moment of attaching to the substratum. Left: lateral view; right: ventral view: Lower images: foot in the moment of releasing the substratum; ventral view, different focus planes. |

  |
| Bdelloid 20; ramate trophi with dental formula (DF) = 2/2. Left: cephalic view; right, caudal view; rami length (RaL): 13µm (1) |
