Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Subclass: Theria Infra class: Eutheria
Order: Artiodactyla
Family: Suidae
Subfamily: Suinae
Genus: Sus Linnaeus,
A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig, its ancestor the wild boar, and several other wild relatives. Pigs
are omnivores and are highly social and intelligent animals. Description and behaviour. 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.[1] 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 foot, with the two larger
central toes bearing most of the
weight, but the outer two also being used in soft ground.[2] The dental formula of adult pigs is , giving a total of 44 teeth.[3] 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.[1] Distribution With
around
2 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet.[4][5] 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 climes of
continental Eurasia and its is lands 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. 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 in to
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. For more information call 08032861326.
