This article is about the Spanish event. For the band, see San Fermin (band). The festival of San FermÃ­n in the city of Pamplona (Navarre, Spain) is a deeply rooted celebration held annually from 12:00, 6 July, when the opening of the party is marked by setting off the pyrotechnic chupinazo, to midnight 14 July, with the singing of the Pobre de MÃ­.
A black jaguar is the same species as a normal-colored jaguar with melanistic coloration causing the fur of the animal to be very dark or black. Melanism occurs because of a dominant gene mutation of the jaguar. The melanistic trait is a result of heredity.
The base coat of the Jaguar is tawny, or it can be reddish/brown, and it has irregular shaped rosette type markings over its body. These markings become solid spots on the head and neck, and they merge to form rings on its tail. The underside of the Jaguar is lighter coloured. Melanistic or black Jaguars are far less common than the spotted form.
