|Colobines are medium-sized primates with long tails
and diverse colorations. The coloring of nearly all the
young animals differs remarkably from that of the
Most species are arboreal, although some live a more
terrestrial life. They are found in many different
habitats of different climate zones (rain forests,
mangroves, mountain forests, and savanah), but not in
deserts and other dry areas. They live in groups, but in
different group forms.
They are almost exclusively herbivores, predominantly
nourishing themselves on leaves, flowers, and fruits.
They occasionally eat insects and other small animals.
To aid in digestion, particularly of hard-to-digest
leaves, they have a multi-chambered, complex stomach.
Unlike the other subfamily of Old World monkeys, the
Cercopithecinae, they possess no cheek pouches.
Gestation averages six to seven months. Young are
weaned for approximately one year and are mature at 3 to
6 years. Their life expectancy is approximately 20 years
