Origin
Sus scrofa is native to parts of Europe, Asia, and North Africa and is the feral form of the common domesticated pig.
Life Cycle
Adult S. scrofa are large mammals that range in length of 60-94 in. (153-240 cm) and can weigh between 146-600 lbs (66-272 kg). Thick, coarse fur covers the body with coloration ranging from black to brownish-red to white. S. scrofa live in large groups may have over 100 individuals with between 6-20 closely-related females. Males leave the group around 1-2 years of age. Feral pigs mate year-round and sexually mature at an early age. Sows have an average of 5-6 piglets in a litter with a range of 1-16. Gestation averages 112-115 days with piglets remaining with the sows until they weigh approximately 55-77 lbs (25-35 kg).
