Leucism is a condition in which there is partial loss of pigmentation in an animal—which causes white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes. It is occasionally spelled leukism. Unlike albinism, it can cause a reduction in multiple types of pigment, not just melanin.
