RADULA FORMULA		A series of numbers indicating the number of MARGINAL TEETH, LATERAL TEETH and the RACHIDIAN TOOTH, and (again) the lateral teeth and marginals. Example: a formula of 3+6+R+6+3 indicates 3 marginal teeth, 6 lateral teeth and 1 rachidian (R) tooth. The radula formula may be simply "1" if the radula is UNISERIATE, having only rachidian teeth. See also: DOCOGLOSSATE; STENOGLOSSATE; RHIPIDOOGLOSSATE; TAENIOGLOSSATE; TOXOGLOSSATE. See the excellent illustrations on Wikipedia.
