Frogs have layers: a comparative histological study of colour polymorphism in Oophaga poison frogs
Spectral reflectance measurements correlated significantly with chromatophore traits, supporting a link between skin histology and colour phenotype, and suggest that colouration in Oophaga arises from less conserved chromatophore unit structure, reflecting diverse evolutionary routes to equivalent colouration.
