What does melanistic mean?
Melanistic describes an organism whose coloring results from an excess or increased distribution of melanin, the pigment responsible for much of the coloration of skin, hair, fur, and feathers. The term is especially associated with rare genetic variants that turn normally reddish or differently colored animals black, as in melanistic foxes, leopards, and birds. Because melanistic coloration can be inherited, occur as a natural mutation, or be deliberately bred, the word appears in biology, zoology, conservation, and pet breeding. It is more precise than simply saying that an animal is “black,” since melanism describes a pigmentation condition rather than every possible source of dark coloration. As a noun, a melanistic is the individual animal or other organism that exhibits the condition. In general use, the term is uncommon, but it is important in scientific and wildlife contexts where the origin and inheritance of unusual coloration may matter.
Having increased melanin pigmentation, especially as a rare inherited condition that produces unusually dark coloration.
"The species occurs in both normal and melanistic forms."
Common in biological, zoological, and wildlife descriptions.
An individual organism, especially an animal, characterized by melanistic pigmentation.
"The melanistic was difficult to distinguish from other dark-coated members of the group."
This noun use is uncommon in everyday speech but recognized in specialist contexts.
Used for multiple organisms that exhibit melanistic pigmentation.
"Several melanistics were released into the breeding population."
Melanism is the rare genetic condition behind nature’s most famous black versions of normally reddish animals, including the black panther.

Etymology of melanistic
The word melanistic was formed from melanism, which combines the Greek melas, meaning “black,” with the suffix -ism. The suffix -istic was then added to form an adjective meaning “characterized by melanism.” The Greek element also underlies related words such as melanin and melanocyte.
