چکیده انگلیسی
The creation of open space to accommodate strongly developed mesenteries is proposed as an explanation for the shortening and radial arrangement of axially free septa in mature Caninia, whereas the development of a slit on an oral disc, increasing water flow through the gastro-vascular cavity, is postulated for Ufimia. Both solutions point towards increased effectiveness of feeding and oxygenation, necessary for the growing organism. Such a conclusion negates the simple application of a given arrangement of septa as an indicator of taxonomic relationship.
