The heteropolarity of the valves is evidenced by small differences in the lengths of the valve halves or differences in the degree to which the apices are drawn out (i.e., one valve end may be more rostrate than the opposing end). The valve face is also asymmetric around the narrow axial area with one half of the valve face wider than the other (
