For the very first occurrence, a Canada lynx with jet-black fur has just been observed and recorded. In the wintertime, Canada lynxes have silvery gray fur that changes to red-brown in the summer.
The journal Mammalia has reported a rare and uncommon discovery of a black-furred lynx, captured on video for the first time just several kilometers south of Whitehorse in Canada's Yukon area. The Canada lynx is a wild cat renowned for tufted ears, huge paws, and a gray or brown fur coat. A lynx, unlike the others, emerged in Yukon territory in August 2020. A brief smartphone video supplied evidence, and the cat is now the topic of a research paper posted in the publication Mammalia by the University of Alberta under the main researcher Thomas Jung.
Mammalia publisher De Gruyter stated in a statement released on Tuesday that the cat was a "rare finding" and that it was the only time a black-coated Canada lynx had been documented, as per Science Alert.
The phone video produced some low-resolution still images, including this view of the lynx walking.

The Rare Black-coated Lynx
Variation in coat color within mammalian species has long been studied, most likely because it has the potential to be adaptive or detrimental. When compared to other felids, coat color in the genus Lynx is rather consistent, with minimal variation among species. The coats of the Canada lynx (Lynx canadensis) are silver-whitish in the winter and reddish brown in the summer, with dark patches and black hairs on the ends of their tails and ears. An uncommon pale color morph, indicating partial albinism, is infrequently found, according to the research.
The black-coated lynx is melanistic, which means it contains more dark pigment in its hair, which gives it its distinctive color. An alert dog could be heard causing a commotion in the footage. The lynx, observed lounging on the ground near several feet in a residential neighborhood, appears indifferent and ultimately moves away.
Melanism in Animals
Canada lynx normally has gray fur in the winter but also brownish coats in the summertime, with few variances. The video was shot from 164 feet away, yet Jung as well as the specialists who reviewed it were able to determine the cat had some light gray fur.
Melanism in wildlife that is ordinarily not darker can be created by random mutations in genes that regulate the production of melanin, according to Germán Orizaola, a senior researcher.
He told Newsweek that the Canada Lynx specific case is fairly most likely the reason because the species' typical coloring is grayish. Modification-generating albinism can occur in various genetics, including gene mutations that seem to be distinct from the ones producing melanism as he added.
The disadvantage of Melanism to the Lynx
During the cold Canadian winter, Canada lynx eventually fades silvery gray, providing animals with camouflage. The lack of concealment during hunting snowshoe hare in the winter, according to the research, is most likely unfavorable, as CNET reported.
Such a shift in behavior had previously been suggested to exist in melanistic leopards, commonly referred to as black panthers, with the darker large cats being found in some locations yet not others, instead of being randomly placed. Regardless, this darker Canada lynx is likely to be at a significant disadvantage throughout the winter months when compared to its silver counterparts, the researchers conclude.
