Leucism in sharks: a histological examination

Journal of Fish Biology, 2023
AbstractIsolated cases of skin pigment disorders, including leucism, in sharks and rays have been reported for multiple species. Nonetheless, the morphological basis behind these chromatic anomalies has not been examined histologically. In this study, the authors quantified and compared the presence of melanin in multiple tissue samples of leucistic ...

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.

Leucism: the prevalent congenital malformation in the olive ridley sea turtle of northwestern Mexico

Diseases of Aquatic Organisms, 2022
Despite being the most abundant sea turtle in the world, the olive ridley turtle Lepidochelys olivacea is classified as Vulnerable by the IUCN. There is evidence of congenital malformations in hatchlings, and the associated causes are multifactorial, with both genetic and environmental sources.

Leucism in Eared Grebes in Western North America

The Condor, 1985
Leucism is the complete loss of a particular pigment, or all pigments, in feathers but not in soft-parts. It may be as slight as a single white feather or as pervasive as an all-white bird with normal eyes, bill, and legs (Buckley 1982). The condition has been documented, usually as a curiosity and under the term "albinism," in hundreds of species. Its

Leucism in neotropical otters (Lontra longicaudis annectens) from Mexico

The Southwestern Naturalist, 2016
Abstract Incidences of atypical color patterns in otters are scarce, particularly for the Neotropical otter (Lontra longicaudis annectens). We report three L. l. annectens individuals, one with partial and two with total leucism; the first otter is from Rio Temascaltepec, state of Mexico, and the other two otters are from Mante, Tamaulipas, Mexico ...

Particle size-independent induction of leucism in Drosophila melanogaster by silver: nano vs. micro

Metallomics, 2016
With the discovery of nanoscience, silver nanoparticles (AgNPs) now appear on the ingredient lists of commercial products along with bulk silver or silver microparticles (AgMPs). In the present study, we have compared the effects of silver in both nano and micro forms to assess whether particle size plays a role in the pigmentation pathway, using ...

A Leucisitic Fisher (Pekania pennanti) and the Prevalence of Leucism in Wild Carnivores

The American Midland Naturalist, 2019
Animal 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

First observation of leucism in the yellow stingray ( Urobatis jamaicensis )

Bulletin of Marine Science
We report the first observed case of leucism in a yellow stingray ( Urobatis jamaicensis ) from Love Beach, New Providence, Bahamas, diagnosed by near-total dorsal depigmentation, a pale blue iris, and residual black spotting. These features exclude albinism, piebaldism, and axanthism.
