Puma  (Puma concolor)

Crepuscular: Active at dawn and dusk.
Inbreeding: The breeding of closely related individuals. An inbred population usually has less genetic variability and this is generally disadvantageous for its long-term survival and success.
Melanism: The expression of dark or black colouration in an animal that is not normally so. These animals are usually not pure black, as any markings can still be seen.
Nocturnal: Active at night.
Subspecies: A population usually restricted to a geographical area that differs from other populations of the same species, but not to the extent of being classified as a separate species.
Ungulates: Hoofed, grazing mammals.
