Scepanotrocha semitecta DONNER 1951
Scepanotrocha semitecta, whirling
Scepanotrocha semitecta, another specimen, whirling. The arrows indicate the 4 nuclei of one of the vitellaria.
Scepanotrocha semitecta: when creeping the whole body is covered by a peristaltic movement going forwards and backwards, which I haven´t observed in other rotifers. The food pills are moved like going through a funnel, which bears resemblance to the movement of the colorless Euglenoid flagellate Astasia klebsii.
Scepanotrocha semitecta: 4 aspects of the head: upper left: the upper lip consisting of two parts (artificially coloured cyan and magenta). Both parts are clearly located above (dorsally) the trochal columns. Upper right : same specimen, focal planes on the trochal columns. Lower left: focal plane on the trophi and ventral cilia of the corona (ventral view). Lower right: rostrum with lamella and cilia while creeping.
Scepanotrocha semitecta: 2 aspects of the foot with spurs and 3 toes.
Scepanotrocha semitecta: trophi with dental formula (DF) 10/10. Although this DF does not correspond with the description of DONNER, the other features fit quite well.
