The boar differs from the hog (which has surely descended from the boar) by shorter body and thicker and longer legs; the boar’s head is longer and thinner, the ears are also longer and upright, the tusks are sharper and stronger. It looks like the animal’s head makes up almost half of the boar’s body.

The body hair coat forms a kind of crest on the animal’s back. The hair coat is of black-brown color with a shade of yellow; the undercoat is brown-grey; the face, tail, lower parts of legs and hooves are black. The body length is up to 2 meters, the height at the shoulder is 95 cm; the adult male species weight can run to 150-200 kilos and sometimes even more.

The movements of the boar are clumsy but quick; its reaction is quicker than that of any other predator. It is very good in swimming and capable to swim quite long distances. The sight sense is poor but smelling and hearing are good. The boars are cautious but not cowardly; when annoyed, wounded or defending their children the boars are very aggressive and dangerous because of their fearsome tusks.

In daytime the boars couch in the dug hole, sometimes in groups. They go out in the evening in order to bathe and find food consisting mainly of vegetation (roots, fruits and acorns) but also different small animals and carrion. They can visit potato, turnip or grain fields bringing a serious damage to farmlands, particularly because they trample the growing crop. The animals often damage young trees. In very rare cases the boars attack quite big animals which are wounded or ill.

The boar is present in many Russian regions; the most part of the European Russia, Southern Siberia.
The boar inhabits places rich in water, boggy areas (both wooded and shrubby ones). The old males live mostly solitarily and join herds only during the coupling period. The female species usually form small herds consisting of 10-30 females and young or weak animals.

The estrum lasts from November to January; there are lots of fights between the males at this time. The gestation lasts for about 18 weeks; the usual number of whelps is 4 to 6. At first they are colored by white, black-brown and yellow stripes that help to camouflage themselves in forest litter. The female carefully protect its children. The reproductive age is reached at 1.5 years; the young animals turn into adult ones at the age of 5-6 years.
