<div class="tree_txt_unlinked"><p>The subfamily Alouattinae is often placed within the same subfamily as Atelinae. Like members of Atelinae, <em>Alouatta</em>
(howling monkeys) have prehensile tails, and are large-bodied. The
howling monkeys are perhaps best-known anatomically for their large
mandibles and expanded hyoid, which forms a hollow, resonating chamber.
Dentally, they have small incisors, large sexually dimorphic canines,
and well developed shearing crests on the upper molars, characteristic
of folivorous primates. Postcranially, their hind- and fore-limbs are
relatively similar in length.</p>
