Which animals often have pink skin and curly tails?

Explanation

Pigs are often pink-skinned. When they are happy, their tails curl. Pigs or domestic pigs are farmed for the consumption of their flesh. You can use pork for a variety of dishes - including chops, gammon, ham and bacon. The blood can be used for blood sausages. The skin is used for clothings. The skin is also used for consumption as a snack in the shape of pork scratching. Dried pigs ears are used for feeding dogs. A pig can have up to 14 nipples and can thus breed more offspring than most other mammals. It derives from the wild boar.
