The gray wolf (Canis lupus) is a member of the Canidae
family and also known as the Arctic wolf, common
wolf, Mexican wolf, Plains wolf, timber wolf, Tundra
wolf. The species was the world's most widely distributed
mammal but has become extinct in much of Western
Europe, in Mexico and much of the USA. Wolves occur
primarily but not exclusively in wilderness and
remote areas. Their original worldwide range has
been reduced by about one-third by deliberate persecution
due to depredation on livestock and fear of attacks
on humans. Although the species still faces some
threats, it is relatively widespread with a stable
population trend and has therefore been assessed
as Least Concern by IUCN since 2004...
