Inventory of color polymorphism in populations of Dendrobates galactonotus (Anura: Dendrobatidae), a poison frog endemic to Brazil
We studied the various color morphs of Dendrobates galactonotus that occur in its range between the Amazon and Tapajós rivers, in the Brazilian states of Pará, Maranhão, northern Mato Grosso, and northern Tocantins. Dorsal coloration ranges from black to light blue and from red via orange to yellow,...

We studied the various color morphs of Dendrobates galactonotus that occur in its range between the Amazon and Tapajós rivers, in the Brazilian states of Pará, Maranhão, northern Mato Grosso, and northern Tocantins. Dorsal coloration ranges from black to light blue and from red via orange to yellow, cream and white, with or without black spots or vermiculations. Most specimens are uniformly black below, but in some populations the color of the back has invaded the ventral surface and the black has been reduced to small areas on the seat patch and under the thighs.
