Titi monkeys are tree-dwelling primates from South America, and live in monogamous family groups that consist of the parents and their offspring. Males and females sit with their long, thick tails intertwined and spend many hours sleeping and grooming each other. The father is the main caretaker for the infants, bringing the infant to its mother only for nursing until the infant is weaned at around 5 months of age. This photo shows an infant titi monkey with its father and mother.
