A multi-level structure has been observed -the first level microstructure on the surface of the scales, the second level nanostructure on the surface of scales as well as internal photonic nanoarchitecture of scales. The overall colouration of scales is pro-vided by the overlap of the optical effects created by these structures. There is some debate about origin and reasons of such complicated structure.
