The Rise of Black Wolf Animal Planet documentary Discovery wild animals HD

A black wolf is a melanistic colour variant of the grey wolf (Canis lupus). Black specimens are recorded among red wolves (Canis lupus rufus), and these color variants are probably still around today. Genetic research from the Stanford University School of Medicine and the University of California, Los Angeles revealed that wolves with black pelts owe their distinctive coloration to a mutation which occurred in domestic dogs, and was carried to wolves through wolf-dog hybridization
