Wildlife of Russia bears and whales. In the taiga forests, species include squirrels, chipmunks, voles and lemmings. The carnivores are polecats, brown bear, lynx, wolves, foxes, wolverines and the sable. Elk, a large deer about in height up to the shoulder, are common in this habitat. Steppe animals include wild boar as well as 30 other mammal species. A small antelope species known a saiga antelope is also present but is under threat due to hunting. Animals species in the Caucasus region are tur (two species of mountain goat), bezoar (wild goat) endangered mouflon (mountain sheep), chamois (an antelope), Persian leopard, brown bear
Domesticated red fox humans. Russian scientists achieved a population of domesticated foxes that are fundamentally different in temperament and behavior from their wild forebears. Some important changes in physiology and morphology became visible, such as mottled or spotted colored fur. Some scientists believe that these changes obtained from selection for tameness are caused by lower adrenaline production in the new population, causing physiological changes within relatively few generations yielding genetic combinations not present in the original species. This indicates that selection for tameness, e.g. did not flee, produces changes that are related to the emergence of other dog-like traits, e.g. raised tail, coming
