Howler monkeys come in nine different species and are
considered the largest among New World monkeys. Native
to Central and South America Howler monkeys belong to
the order of primates and the genus Alouatta. Howlers are foliovores by nature
and eat leaves and seeds.
Distinguishing features of the Howler monkey include a
prehensile tail that is strong enough to allow for climbing and movement in the
trees. They can grow to 60 inches in height (not including their tails) and
have wide set nostrils and thick short snouts.
Living in groups of 18 or so, howler monkeys have a larger
number of females than males in their packs. This reduces sexual competition
and the number of physical fights among members. Howler monkeys spend 80
percent of their time living in the tree tops avoid capture for hunting or
captivity.
The Howler monkey's vocal calls can be heard over a radius
of three miles. It is considered one of the loudest animals on the planet.
