Peccaries have poor vision, fair hearing and a keen sense of smell. Gestation lasts about 115 days. They usually have twins, but the litter can consist of one to four young. Lactation lasts six to eight weeks, but young remain with the mother two to three months. They mark their boundaries with secretion from their rump on trees or rocks.
Most peccaries never travel far from their place of birth.
When excited, a musk gland located on the rump opens and exudes a foul-smelling secretion. Peccaries are immune to some snake venoms. All rights reserved.
