| Hexarthra mira, lateral view of specimen from (2) showing the unpaired ventral appendage. vab: abductor muscle of the ventral appendage; vad: adductor muscle of the ventral appendage.(2) |

 |
| Hexarthra mira, optical lateral transect; focal plane on the dorsal antenna (dA); one of two eyespots with lens and chin (Ch)/ lower lip. (dTr: dorsal part of the trochus; RM: retractor muscle; vTr. ventral part of the trochus. |

 |
| Hexarthra mira, dorsoventral view, focal plane on the caudal appendages (arrowheads) (1) |
| |
 |
| Hexarthra mira, is one of the few genera with motile cilia at the posterior part (another genus is Testudinella with motile cilia at thhe foot) here at the caudal appendages (arrows). (4) |
| |
 |
| Hexarthra mira, frontal view on the corona of a swimming specimen showing the metachronal movement of the trochal cilia which is counter-clockwise. Also in focus is the buccal field (arrowheads) and the cilia of the "chin" (i.e. the lower lip/ cingulum (arrow)) Still image of a YT-video that shows the metachronal movement of the trochal cilia.(4) |
| |
 |
| Hexarthra mira, frontal view on the corona of a swimming specimen; optical transect, focal plane on the dorsal antenna (dA), the two red eyespots and the mouth (asterisk). The arrwoheads mark (part of the trochus; the arrows mark the cilia of the circumapical band and the cingulum. loL: lower lip. (4) |

 |
| Hexarthra mira, crop of the first image. vab: abductor muscle of the ventral appendage; vad: adductor muscle of the ventral appendage. (2) |
| |
 |
| Hexarthra mira, ventral appendage in dorsoventral view. vab: abductor muscle of the ventral appendage; vad: adductor muscle of the ventral appendage. (3) |
| |
 |
| Hexarthra mira, in contrast to the unpaired ventral appendage the paired lateral apendages have only a single abductor muscle.(3) |
