Leucistism is a genetic feature due to a recessive gene that gives a white color to the coat or plumage of certain individuals of a species. Leucistism is different from albinism: the eyes remain of their normal color and the leucistic animals are not sensitive to the sun. On the contrary, they would even be slightly more resistant. The white color has a high albedo and protects more from heat. Among leucistic animals one can find, besides the white lion, the white tiger, the white blackbird, the white deer, the white peacock, or even the white alligator.
