The concentration-dependent structural transition of sepia melanin in water is analyzed. This biopolymer at high concentration gives the well-known nanospheres, whereas sample dilution gives unforeseen nanofibres exhibiting the structural features of mature amyloid fibrils. We propose a mechanism of pigment self-assembly dependent on the interaction of residual melanosomal protein(s) with eumelanin heteropolymer. Our results contribute to understanding the peculiar physico-chemical properties of this ubiquitous pigmentEuropean Union's Seventh Framework Programme (FP7/2007–2013) under grant agreement No. REGPOT-CT2012–316331-POLARISTaylor and FrancisUniversidade do MinhoSrisuk, PathomthatCorrelo, V.
