<div class="tree_txt_unlinked"><p>Colobines
are the leaf-eating cercopithecoids, separated into the colobus monkeys
(Africa) and the langurs (Asia). Colobines are considered to be more
anatomically specialized compared to cercopithecines, and are easily
distinguished from the latter by their sharp-cusped molars and
relatively narrow incisors. Their crania exhibit a broader interorbital
region, and their jaws are deeper compared to cercopithecines.
Postcranially, they have relatively longer legs, and short or absent
thumbs. They also have a complex, sacculated stomach (like a cow) that
houses bacterial colonies for digesting complex cellulose. In general,
they are relatively more folivorous and arboreal than cercopithecines.</p>
