A genetic mutation causes some animals to have darker pigmentation, resulting in unusual coloration. This condition, known as melanism, can produce animals with jet black fur. A rare example of this has been documented, with photos of a melanistic gray fox being shared by officials.

These photos were taken in June 2019 and have been making waves on social media. They were submitted through a portal used to survey the species' population.

Further details about this rare sighting are available, including comparisons to other examples of melanism in the region.
