A Leucisitic Fisher (Pekania pennanti) and the Prevalence of Leucism in Wild Carnivores
American Midland Naturalist, 2019Animal coloration has adaptive roles for communication, concealment, sexual selection, and physiological function. Genetic mutations sometimes cause abnormal coloration such as leucism, in which an animal appears partially or entirely white, except for exposed soft skin tissue. Here we document a leucistic fisher (Pekania pennanti). Fisher fur normally

Leucism in Two Tri-colored Bats (Perimyotis subflavus) in Texas
Southeastern Naturalist, 2017(Uploaded by Plazi for the Bat Literature Project) Although aberrant coloration is known to occur in mammals, few records of the phenomenon exist in the literature for North American bats. Here we report on 2 leucistic Perimyotis subflavus (Tri-colored Bats) in Leon County, TX, that had a distinct white patch on their bodies.
