Black Barn Owl
You’ve come across many leucistic animals, but what’s the opposite? Melanism is a development of dark-colored pigment, and that’s what this barn owl has. Therefore, it looks entirely different than its species (the white-and-tan buddy alongside it).
Stripes and Spots
The zebra below is another example of how melanism works. Typically, they have dark fur, and patches of the coat appear striped or spotted. It often looks weird to humans, but it actually helps them blend into their environments.
