The term "boar" is used to denote an adult male of certain species – including, confusingly, domestic pigs. However, for wild boar, it applies to the whole species, including, for instance, "sow wild boar" or "wild boar piglet" [cite web

The body of the wild boar is compact; the head is large, the legs relatively short. The
furconsists of stiff bristles and usually finer fur. The colour usually varies from dark grey to black or brown, but there are great regional differences in colour; even whitish animals are known from central Asia.V. G. Heptner and A. A. Sludskii: "Mammals of the Soviet Union Vol. II, Part 2 Carnivora (Hyaenas and Cats)". Leiden, New York, 1989 ISBN 900408876 8] During winter the fur is much denser.
Adult boars average 100-150 cm in length and have a shoulder height of 90 cm. As a whole, their average weight is 60-70 kilograms (132-154 pounds), though boars show a great deal of weight variation within their geographical ranges. Boars shot in
Tuscanyhave been recorded to weigh 150 kg (331 lbs). A French specimen shot in Negremont forest in Ardennein 1999 weighed 227 kg (550 lbs). Carpathianboars have been recorded to reach weights of 200 kg (441 lbs), while Romanian and Russian boars can reach weights of 300 kg (661 lbs).
The continuously growing
tusks (the canine teeth) serve as weapons and burrowing tools. The lower tusks of an adult male measure about convert|20|cm|in|abbr=on (from which seldom more than convert|10|cm|in|abbr=on protrude out of the mouth), in exceptional cases even convert|30|cm|in|abbr=on. The upper tusks are bent upwards in males, and are regularly ground against each other to produce sharp edges. In females they are smaller, and the upper tusks are only slightly bent upwards in older individuals.
Wild boar piglets are coloured differently from adults, being a soft brown with longitudinal darker stripes. The stripes fade by the time the piglet is about half-grown, when the animal takes on the adult's grizzled grey or brown colour.
Wild boars live in groups called "sounders". Sounders typically contain around 20 animals, but groups of over 50 have been seen. In a typical sounder there are two or three sows and their offspring; adult males are not part of the sounder outside of a breeding cycle, two to three per year, and are usually found alone. Birth, called farrowing, usually occurs in a secluded area away from the sounder; a litter will typically contain 8-12 piglets.(p. 6) The animals are usually
nocturnal, foraging from dusk until dawn but with resting periods during both night and day.(p. 4-5, 8-9) They eat almost anything they come across, including grass, nuts, berries, carrion, roots, tubers, refuse, insects, small reptiles--even young deerand lambs.(p. 9-10)
Boars are the only hoofed animals known to dig burrows, a habit which can be explained by the fact that they are the only known mammals lacking
brown adipose tissue. Therefore, they need to find other ways to protect themselves from the cold. For the same reason, piglets often shiver to produce heat themselves. [cite web
title=Shiver Me Piglets!
quote=Most newborn mammals are kept warm by a reaction in the mitochondria involving brown fat tissue; which converts fats into heat. Pigs lack this mechanism and so shudder in order to maintain their body temperature.
If surprised or cornered, a boar (and particularly a sow with her piglets) can and will defend itself and its young with intense vigor. The male lowers its head, charges, and then slashes upward with its tusks. The female, whose tusks are not visible, charges with its head up, mouth wide, and bites. Such attacks are not often fatal to humans, but can easily result in severe trauma, dismemberment, or blood loss.
The wild boar was originally found in
North Africaand much of Eurasiafrom the British Islesto Japanand the Sunda Islands. In the north it reached southern Scandinaviaand southern Siberia. Within this range it was absent in extremely dry deserts and alpine zones.
A few centuries ago it was found in North Africa along the
Nilevalley up to Khartumand north of the Sahara. The reconstructed northern boundary of the range in Asia ran from Lake Ladoga(at 60°N) through the area of Novgorodand Moscowinto the southern Ural, where it reached 52°N. From there the boundary passed Ishimand farther east the Irtyshat 56°N. In the eastern Baraba steppe(near Novosibirsk) the boundary turned steep south, encircled the Altai Mountains, and went again eastward including the Tannu-Ola Mountainsand Lake Baikal. From here the boundary went slightly north of the Amur Rivereastward to its lower reaches at the China Sea. At Sachalinthere are only fossilreports of wild boar. The southern boundaries in Europe and Asia were almost everywhere identical to the sea shores of these continents. In dry deserts and high mountain ranges, the wild boar is naturally absent. So it is absent in the dry regions of Mongoliafrom 44-46°N southward, in Chinawestward of Sichuanand in Indianorth of the Himalaya. In high altitudes of Pamirand Tien Shanthey are also absent; however, at Tarim basinand on the lower slopes of the Tien Shan they do occur.V. G. Heptner and A. A. Sludskii: "Mammals of the Sowjetunion Vol. II, Part 2 CARNIVORA (Hyaenas and Cats)". Leiden, New York, 1989 ISBN 900408876 8]
In recent centuries, the range of wild boar changed dramatically because of hunting by humans. They probably became extinct in
Great Britainin the 13th century: certainly none remained in southern England by 1610, when King James I reintroduced them to Windsor Great Park. This attempt failed due to poaching, and later attempts met the same fate. By 1700 there were no wild boar remaining in Britain.
Denmarkthe last boar was shot at the beginning of the 19th century, and in 1900 they were absent in Tunisiaand Sudanand large areas of Germany, Austriaand Italy. In Russiathey were extinct in wide areas in the 1930s, and the northern boundary has shifted far to the south, especially in the parts to the west of the Altai Mountains.
By contrast, a strong and growing population of boar has remained in
France, where they are hunted for food and sport, especially in the rural central and southern parts of that country.
By 1950 wild boar had once again reached their original northern boundary in many parts of their Asiatic range. By 1960 they reached
Saint Petersburgand Moscow, and by 1975 they were to be found in Archangelskand Astrakhan. In the 1970s they again occurred in Denmark and Sweden, where captive animals escaped and survive in the wild. In the 1990s they migrated into Tuscanyin Italy.
tatus in Britain
Between then and the 1980s, when wild boar farming began, only a handful of captive wild boar, imported from the continent, were present in Britain. Because wild boar are included in the
Dangerous Wild Animals Act 1976, certain legal requirements have to be met prior to setting up a farm. A licence to keep boar is required from the local council, who will appoint a specialist to inspect the premises and report back to the council. Requirements include secure accommodation and fencing, correct drainage, temperature, lighting, hygiene, ventilation and insurance. Occasional escapes of wild boar have occurred since the 1970s. Early escapes occurred from Wildlife Parks, but since the early 1990s more escapes have been from farms, the number of which has increased as the demand for wild boar meat has grown. By the 1990s, a breeding population was rumoured to have established in areas of Kentand East Sussex. In 1998, a MAFF (now DEFRA) study on wild boar living wild in Britain confirmed the presence of two populations of wild boar living in Britain, one in Kent and East Sussex and another in Dorset. Populations of Wild Boar have however been sighted in other areas such as Herefordshireand Gloucestershire.
tatus in Germany
Recently, Germany has reported a surge in the wild boar population. This 320% growth in population during 2007--greater than in any other European country--has led to an increasing number of problems for Germany. Crops have been destroyed and dug up, pets and other animals killed, gardens, cemeteries, and graveyards have been trampled, and even the dead have been dug up. Evermore frequent attacks on humans and the risk of swine fever have the German population concerned about the unprecedented population boom. Studies cite the number of piglets in a typical German wild boar litter is a potential feeder for the problem. According to one such study, "German [wild boar] litters have six to eight piglets on average, other countries usually only about four or five." [http://news.yahoo.com/s/nm/20081003/od_nm/us_boar_1]
The wild boar is divided into over 11 different subspecies, of which six are present in Europe.
*"Sus scrofa scrofa": The most common and most widespread subspecies, its original distribution ranges from France to European Russia. It has been introduced in Sweden, Norway, the USA and Canada.it iconcite book | author= Scheggi, Massimo | title= La Bestia Nera: Caccia al Cinghiale fra Mito, Storia e Attualità | year= 1999 | pages= pp.201 | id=ISBN 8825379048 ]
*"Sus scrofa baeticus": A small subspecies present in the Iberian Peninsula.
*"Sus scrofa castilianus": Larger than "baeticus", it inhabits northern Spain.
*"Sus scrofa meridionalis": A small subspecies present in Sardinia.
*"Sus scrofa majori": A subspecies smaller than "scrofa" with a higher and wider skull. It occurs in central and southern Italy. Since the 1950s, it has hybridized extensively with introduced "scrofa" populations.
*"Sus scrofa attila": A very large subspecies ranging from Romania, Hungary, in Transylvania and in the Caucuses up to the Caspian Sea. It is thought that boars present in Ukraine, Asia Minor and Iran are part of this subspecies.
*"Sus scrofa ussuricus" (northern Asia and

domestic pigis usually regarded as a further subspecies, "Sus scrofa domestica" – but sometimes as a separate species, "Sus domestica". Different subspecies can usually be distinguished by the relative lengths and shapes of their lacrimal bones. "S. scrofa cristatus" and "S. scrofa vittatus" have shorter lacrimal bones than European subspecies.cite book | author = Clutton-Brock, Juliet| title = A Natural History of Domesticated Mammals | year = 1987 | pages = pp.208 | isbn = 0521346975] Spanish and French boar specimens have 36 chromosomes, as opposed to wild boar in the rest of Europe which possess 38, the same number as domestic pigs. Boars with 36 chromosomes have successfully mated with animals possessing 38, resulting in fertile offspring with 37 chromosomes. [ [http://www.britishwildboar.org.uk/profile.html Wild boar profile ] ]
Domestic pigs quite readily become
feral, and feral populations often revert to a similar appearance to wild boar; they can then be difficult to distinguish from natural or introduced true wild boar (with which they also readily interbreed). The characterization of populations as feral pig, escaped domestic pig or wild boar is usually decided by where the animals are encountered and what is known of their history. In New Zealand, for example, feral pigs are known as "Captain Cookers" from their supposed descent from liberations and gifts to Māoriby explorer Captain James Cookin the 1770s. [cite book| last = Horwitz| first = Tony| authorlink = Tony Horwitz| coauthors =| title = | publisher = Picador| date = 2003| location =| pages = 127| url =| doi =| isbn = 0312422601 ] New Zealand feral pigs are also frequently known as "tuskers", due to their appearance.
One characteristic by which domestic and feral animals are differentiated is their coats. Feral animals almost always have thick, bristly coats ranging in colour from brown through grey to black. A prominent ridge of hair matching the spine is also common, giving rise to the name "
razorback" in the southern United States, where they are common. The tail is usually long and straight. Feral animals tend also to have longer legs than domestic breeds and a longer and narrower head and snout.

At the beginning of the 20th century, wild boar were introduced for hunting in the
United States, where they interbred in parts with free roaming domestic pigs. In South America, New Guinea, New Zealand, Australiaand other islands, wild boar have also been introduced by humans and have partially interbred with domestic pigs.
In South America, also during the early 20th century, free-ranging boars were introduced in
Uruguayfor hunting purposes and eventually crossed the border into Brazilsometime during the 1990s, quickly becoming an invasive species, licensed private hunting of both feral boars and hybrids ("javaporcos") being allowed from August 2005 on in the Southern Brazilian state of Rio Grande do Sul[www.institutohorus.org.br/download/marcos_legais/INSTRUCAO_NORMATIVA_N_71_04_agosto_2005.pdf] , although their presence as a pest had been already noticed by the press as early as 1994 ["Javali: fronteiras rompidas" ("Boars break across the border") "Globo Rural" 9:99, January 1994, ISSN 0102-6178, pgs.32/35] . Releases and escapes from unlicensed farms (established because of increased demand for boar meat as an alternative to pork), however, continued to bolster feral populations and by mid-2008 licensed hunts had to expanded to the states of Santa Catarinaand São Paulo[/www.arroiogrande.com/especiais_javali.htm] .
Recently-established Brazilian boar populations are not to be confused with long established populations of feral pigs ("porcos monteiros"), which have existed mainly in the
Pantanalfor more than a hundred years, along with native peccaries. The demographic dynamics of the interaction between feral pigs populations and those of the two native species of peccaries ( Collared Peccaryand White-lipped Peccary) is obscure and is being studied presently. It has been proposed that the existence of feral pigs could somewhat ease jaguarpredation on peccary populations, as jaguars would show a preference for hunting pigs, when these are available [www.cienciahoje.uol.com.br/controlPanel/materia/view/3835] .
As of 2008, the estimated population of 4 million feral hogs cause an estimated
US$800 million of property damage a year in the U.S. [cite web

tigers in the regions where they coexist. [ [http://www.tigers.ru/books/ecolog/ch13_en.html Yudakov, A. G. and I. G. Nikolaev, The Ecology of the Amur Tiger [Chapter 13 ] ]
Wolves are also major predators of boars in some areas. Wolves mostly feed on piglets, though adults have been recorded to be taken in Italy, the Iberian Peninsula and Russia. Wolves rarely attack boars head on, preferring to tear at their
perineum, causing loss of coordination and massive blood loss. In some areas of the former Soviet Union, a single wolf pack can consume an average to 50-80 wild boars annually.cite book | author = Graves, Will |url = http://www.wolvesinrussia.com/ | title = Wolves in Russia: Anxiety throughout the ages | year = 2007 | pages = pp.222 | id = ISBN 1550593323] In areas of Italy where the two animals are sympatric, the extent to which boars are preyed upon by wolves has led to them developing more aggressive behaviour toward both wolves and domestic dogs. Striped hyenas occasionally feed on boars, though it has been suggested that only hyenas from the three larger subspecies present in Northwest Africa, the Middle East and India can successfully kill them.cite web | url = http://www.hyaena.ge/striped.htm | title = Striped Hyaena "Hyaena (Hyaena) hyaena" (Linnaeus, 1758) | publisher = IUCN Species Survival Commission Hyaenidae Specialist Group | accessdate = 2008-05-21 | month = May | year = ]
The hair of the boar was often used for the production of the
toothbrushuntil the invention of synthetic materials in the 1930s. [cite web
accessdate=2007-06-21] The hair for the bristles usually came from the neck area of the boar. While such brushes were popular because the bristles were soft, this was not the best material for
oral hygieneas the hairs were slow to dry and usually retained bacteria. Today's toothbrushes are made with plastic bristles.
Boar hair is used in the manufacture of boar-bristle hairbrushes, which are considered to be gentler on hair--and much more expensive--than common plastic-bristle hairbrushes. However, among shaving brushes -- which are almost exclusively made with animal fibers -- the cheaper models use boar bristles, while badger hair is used in much more expensive models. [http://www.menessentials.com/oxid.php/sid/x/shp/oxbaseshop/cl/info/tpl/shave_brush.tpl]
Boar hair is used in the manufacture of paintbrushes, especially those used for oil painting. Boar bristle paintbrushes are stiff enough to spread thick paint well, and the naturally split or "flagged" tip of the untrimmed bristle helps hold more paint.
Despite claims that boar bristles have been used in the manufacture of premium
dart boards for use with steel-tipped darts, these boards are, in fact, made of other materials and fibers – the finest ones from sisal rope.
In many countries, boar are farmed for their meat, and in countries such as France, for example, boar ("sanglier") may often be found for sale in butcher shops or offered in restaurants (although the consumption of wild boar meat has been linked to transmission of
Hepatitis Ein Japan). [cite journal |author=Li T-C, Chijiwa K, Sera N, Ishibashi T, Etoh Y, Shinohara Y, et al.|title=Hepatitis E Virus Transmission from Wild Boar Meat|journal=Emerg Infect Dis [serial on the Internet] |year=2005 |url=http://www.cdc.gov/ncidod/EID/vol11no12/05-1041.htm]
Mythology, fiction and religion
Greek mythology, two boars are particularly well known. The Erymanthian Boarwas hunted by Heraclesas one of his Twelve Labours, and the Calydonian Boarwas hunted in the "Calydonian Hunt" by dozens of other mythological heroes, including some of the Argonautsand the huntress Atalanta.
Celtic mythologythe boar was sacred to the goddess Arduinna, [ [http://www.isle-of-skye.org.uk/celtic-encyclopaedia/celt_b2b.htm Celtic Encyclopaedia] ] [ [http://www.les-ardennes.net/images/photos/arduina.jpgles-ardennes.net] ] and boar hunting features in several stories of Celtic and Irish mythology. One such story is that of how Fionn mac Cumhaill("Finn McCool") lured his rival Diarmuid Ua Duibhneto his death - gored by a wild boar. Ares, the Greek god of war, had the ability to transform himself into a wild boar, and even gored his son to death in this form to prevent the young man from growing too attractive and stealing his wife, similar to Oedipusmarrying his own mother.
The Norse gods
Freyrand Freyjaboth had boars. Freyr's boar was named Gullinbursti("Golden Mane"), who was manufactured by the dwarf Sindri due to a bet between Sindri's brother Brokkrand Loki. The bristles in Gullinbursti's mane glowed in the dark to illuminate the way for his owner. Freya rode the boar Hildesvini(Battle Swine) when she was not using her cat-drawn chariot. According to the poem " Hyndluljóð", Freyja concealed the identity of her protégé Óttar by turning him into a boar. In Norse mythology, the boar was generally associated with fertility.
In Persia (Iran) during the
Sassanid Empire, boars were respected as fierce and brave creatures, and the adjective "Boraz (Goraz)" (meaning boar) was sometimes added to a person's name to show his bravery and courage. The famous Sassanid spahbod, Shahrbaraz, who conquered Egyptand the Levant, had his name derived "Shahr(city) + Baraz(boar like/brave)" meaning "Boar of the City".Fact|date=January 2008
