The pattern formed by the scale margins. Most scale patterns are waved, although not all to the same extent. Patterns may described as regular, irregular or streaked. A regular waved pattern is one in which the waves are of almost equal wavelength and equal amplitude; an irregular wave pattern is one in which the waves are of unequal wavelength and amplitude. A streaked wave is one in which the waves are interrupted by steeply inclined scale margins. The term waved is frequently used in conjunction with another adjective e.g., waved crenate margins. Other scale-patterns are : Chevron, Crenate, Mosaic, Pectinate, Petal, Rippled
