pills in the digestive system
Bdelloid rotifers of the family Habrotrochidae do not have a stomach lumen, instead there is a syncytial mass. The diet is formed into pills in a short chamber behind the mastax, and the pills are digestetd in the stomach protoplasm. So all rotifers of the genera: Habrotrocha, Otostephanos and Scepanotrocha have pills. Here are only some examples given. In certain species the pills are not clearly visible (for example Habrotrocha tripus). By feeding the living specimens with carmine it is possible to decide if a stomach lumen is present or not. Some specimens of other families of Bdelloidea also may have pill-like diet as well; therefore in all cases it is important to check for the stomach lumen.
