The Eurasian Wolf (Canis lupus lupus), also known as the European, Common or Forest Wolf is one of the 39 subspecies of grey wolf (Canis lupus). The Eurasian Wolf has the largest range among wolf subspecies and is the most common in Europe and Asia, ranging through Mongolia, China, Russia, Scandinavia, Western Europe and the Himalayan Mountains. The size of Eurasian wolves is subject to geographic variation with animals in Russia and Scandinavia being larger and bulkier than those residing in Western Europe. Adults from Russia measure 90 - 160 cm in length, 65 - 85 cm in shoulder height and weigh on average 32–50 kg, with a maximum weight of 69–80 kg. Their fur is known to be shorter and more dense as compared to the North American wolf. Their colors range from gray, white, cream, red, grey and black, sometimes with all colors combined. Eurasian wolves feed on ungulates and rodents, fruits, berries, and fish. Depending on availability of prey, gray wolves may or may not hunt in packs.
