Pigs include the domestic pig and its ancestor, the common Eurasian wild boar (Sus scrofa), along with other species; related creatures outside the genus include the babirusa and the warthog. Pigs, like all suids, are native to the Eurasian and African continents. Juvenile pigs are known as piglets.[1] Pigs are omnivores and are highly social and intelligent animals A typical pig has a large head with a long snout which is strengthened by a special prenasal bone and by a disk of cartilage at the tip.[3] The snout is used to dig into the soil to find food and is a very acute sense organ. There are four hoofed toes on each trotter (foot), with the two larger central toes bearing most of the weight, but the outer two also being used in soft ground.[4] The dental formula of adult pigs is 3.1.4.33.1.4.3, giving a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth form tusks, which grow continuously and are sharpened by constantly being ground against each other seehttp://en.wikipedia.org/wiki/Pig With around 1 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet.[5][6] The ancestor of the domesticated pig is the wild boar, which is one of the most numerous and widespread large mammals. Its many subspecies are native to all but the harshest climates of continental Eurasia and its islands and Africa as well, from Ireland and India to Japan and north to Siberia. Although it has been exterminated in some areas, its numbers are stable, or even increasing rapidly, in most of its native range.[citation needed] Long isolated from other pigs on the many islands of Indonesia, Malaysia, and the Philippines, pigs have evolved into many different species, including wild boar, bearded pigs, and warty pigs. Humans have introduced pigs into Australia, North and South America, and numerous islands, either accidentally as escaped domestic pigs which have gone feral, or as wild boar. These have typically adapted well, and are increasing in number and broadening their range outside human control
