Unlike radially symmetrical organisms which can be cut divided equally along many planes, biradial organisms can only be cut equally along two planes. Cnidarians contain specialized cells known as cnidocytes (“stinging cells”), which contain organelles called nematocysts (stingers). An alga (Micrasterias rotata) with two perpendicular axes of reflection symmetry (dashed lines; biradial symmetry or disymmetry).B. In bilateral symmetry there are the same three axes as in biradial symmetry but only one pair of symmetrical sides, the lateral sides, since the other two sides, called the dorsal (back) and ventral (belly) surfaces, are unlike. Including the anteroposterior axis, there are also two other axes or planes of symmetry at right angles to it and to each other: the axes sagittal, or median vertical-longitudinal, and the axes transverse, or cross. Symmetry amongst animals can generally be sorted into these categories: 1.
