A black panther is a
black (melanistic) color
variant of one of several
species of larger cat which
are often known by the term
panther. "Panther" in
North America is most
commonly used for the cougar
(genus Puma), in
Latin America it is most
often used to mean a jaguar
and elsewhere in the world
it usually refers to the
leopard (both genus
Panthera). Panthers are
not necessarily black, but
may also be normally colored
for the species (tawny or
spotted), or white.
