| Well, I guess it is a new Panther since in the advert for the new XE Jaguar they feature a Panther, not a Jaguar. Are the animals now extinct perhaps? |

Color morphism
A melanistic jaguar is a color morph which occurs at about 6% frequency in populations.
Color morphism occurs in the species. A near-black melanistic form occurs regularly. Jaguars with melanism appear entirely black, although their spots are still visible on close examination.
The black morph is less common than the spotted form but, at about six percent of the population,[39] it is several orders of magnitude above the mutation rate. Hence, it is being supported by selection. Some evidence indicates the melanism allele is dominant.[40] The black form may be an example of heterozygote advantage; breeding in captivity is not yet conclusive on this.
Melanistic jaguars are informally known as black panthers, but (as with all forms of polymorphism) they do not form a separate species.
Extremely rare albino individuals, sometimes called white panthers, also occur among jaguars, as with the other big cats.[34] As usual with albinos in the wild, selection keeps the frequency close to the rate of mutation. _________________ Bristols should always come in pairs.

There I was thinking that someone had bought the rights of the Phelon & Moore 'Panther' motorcycle in the same way as the new versions of Ariel, Matchless and Brough Superior. _________________ Keep Torqueing,
