Mammals: Pig


Domesticated pigs come in many shapes and sizes. Although stout with short legs, pigs are surprisingly fast. The Chinese domesticated the pig over 7,000 years ago, making it the first animal domesticated by humans.

Where do they live?:

Domesticated pigs can be found on all continents except Antarctica.

What do they eat?:

Pigs are omnivorous and scavengers and will eat almost anything.

Social Environment:

Pigs are very social and communicate with each other in a language of calls, snorts, sniffs, and whistles.

Critter Fact:

Pigs don't have sweat glands; they wallow in mud or water to maintain a comfortable body temperature. Wallowing also protects them from sunburn and insect bites. They have been known to wallow in their own urine to keep cool.
