7. Black Squirrel:
The black squirrel occurs as a “melanistic” subgroup of both the eastern gray squirrel and the fox squirrel.
The overall population of black squirrels is small when compared to that of the gray squirrel. The black fur color can occur naturally as a mutation in populations of gray squirrels, but it is rare. The rarity of the black squirrel has caused many people to admire them, and the black squirrels enjoy great affection in some places as mascots. In several U.S. states, as well as in Canada and the United Kingdom, black squirrels have been introduced into the wild in the hope of increasing their numbers.
8. Black Panthers:
A black panther is the melanistic color variant of any Panthera species. Black panthers in Asia and Africa are leopards (Panthera pardus) and black panthers in the Americas are black jaguars (Panthera onca).
