Definition
Black squirrels are actually just gray squirrels with a genetic mutation that causes their fur to be black π€. They are a melanistic subgroup, meaning they have a high amount of melanin, the pigment responsible for dark coloration. Black squirrels are not a separate species. They are simply a color variation within the gray squirrel population. Think of it like having different hair colors in humans; same species, different look. They are often found in urban areas.
