Pigs
Pigs are mammals with stocky bodies, flat snouts that can move independently of their heads, small eyes and large ears. They are highly intelligent, social animals, and are found all over the world.
Pigs are in the Suidae family, which includes eight genera and 16 species. Among those species are wild boars, warthogs, Pygmy hogs and domestic pigs.
Pigs usually weigh between 300 and 700 lbs. (140 and 300 kilograms), but domestic pigs are often bred to be heavier.
Boars, pigs and hogs live all over the world, except for Antarctica, northern Africa and far northern Eurasia, according to the Encyclopedia of Life.
Pigs are very intelligent animals. According to a review published in 2015 in the International Journal of Comparative Psychology, pigs are "cognitively complex," sharing many traits with animals that are typically considered to be highly intelligent.
Fun facts:
- There are around 2 billion pigs in the world.
- Often is believed that pigs can't look up, they actually can but they don't need to look straight up, their neck doesn't let them look straight up, but they can still look.
