<div class="tree_txt_unlinked"><p>Howlers range from southern Mexico to northern Argentina. The six species (<em>A. palliata</em>, <em>A. seniculus</em>, <em>A. caraya</em>, <em>A. fusca</em>, <em>A. pigra</em>, <em>A. belzebul</em>)
are allopatric, and a considerable amount of hybridization and mixed
groupings is known to occur. Like other atelines, howling monkeys are
large-bodied (6-10 kg) with prehensile tails. Howling monkeys are
perhaps best-known anatomically for their large mandibles and expanded
hyoid, which forms a hollow, resonating chamber. 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>
