Superficial features of the shell can be misleading but these are true body subdivisions of Rojenö of each superclass. This is more apparent in the true body but even then divisions may still be hard to pinpoint, especially in the highly modified Poteta.

Another type of body division in Rojenö is their radial symmetry. All Rojenö, without exceptions, possess full radial symmetry, a traditional body plan among telinu (though this is not always outwardly apparent). Generally, Rojenö possess eightfold radial symmetry but this is often reduced to sixfold, especially in Poteta.
