Pigs are often seen as dirty animals because of their habit to roll in mud but actually they are quite clean! They only roll in mud because they need to cool off. Pigs are also known as hogs. Male pigs of any age are called boars and female pigs are called sows. Pigs can be found all over the world, and provide useful things to humans fertilizer and even some medicines.

Wild pigs eat things like roots and leaves while pigs on farms eat things like corn, but in Europe, they also eat barley. Female pigs give birth to young called piglets. They usually take care of the piglets for 3 to 5 weeks. Piglets can weigh roughly 2.5 pounds (1.1 kilograms) as a new-born, and as adults, they weigh roughly between 300 and 700 pounds (140 and 300 kilograms). Pigs do not have the best eyesight, but they have a good sense of smell. Pigs’ nostrils are on their snout, which is very sensitive. The pig uses the snout to search for food.
