Title: Not just a leather
Specie: Peacock Indian Peafowl

Description: The feather of a peacock has been attracting scientific research for more than 300 years thanks to its aesthetic. There are a lot of barbs sticking out from the main shaft of the peacock's leather, and each barb has many barbules (figure a). The typical dimension of a barbule is between 20-30μm. They are curved along their long axis and slightly twisted from the roots. The surfaces of which are smoothly curved like the shape of a saddle (figure b). Under high magnification, 8–12 layers consisting of periodically arrayed particles are observed beneath the surface layer (figure c). The sophisticated color-producing structure in the leather of a peacock was clarified by using an electron microscope as illustrated in figure d.
