Colobinae

The Colobinae are a subfamily of Old World monkeys, also known as leaf monkeys. This subfamily includes colobus monkeys native to Africa and langurs found in Asia.12

Colobinae are characterized by their long tails, slender bodies, and specialized digestive systems adapted for fermenting a vegetarian diet, primarily leaves. However, their diet is not exclusively leaves; they also consume fruits, flowers, and seeds depending on the season.123

Colobus monkeys are diurnal and arboreal, known for their long leaps between trees. They are distinguished by color: black-and-white colobus, red colobus, and olive colobus. Langurs, also known as leaf monkeys, are gregarious and diurnal, with long tails and slender limbs. Their coloration varies by species, and newborns often have a different color than adults.12

Some species within the Colobinae subfamily, particularly certain red colobus subspecies, are endangered due to habitat loss and other factors.12
