A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. 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.
