Large monkey of the rainforest
Howlers are the largest monkeys in the rainforest. Howler monkeys have a short snout, and wide-set, round nostrils. They range in size from 2 to 3 feet, excluding their tail which can be equally as long. Like many monkeys of the rainforesr, they have prehensile tails. Males are, on average, 2 to 3 lbs heavier than females.
Most howler monkey species live in groups of 10 to 15 animals, with one to three adults males and multiple females. Physical fighting among group members is infrequent and generally of short duration. However, serious injuries can result. Both males and females may fight with each other but physical aggression is even more rare between sexes.
As their name suggests, vocal communication forms an important part of their social behavior. Group males generally call at dawn and dusk as well as interspersed times throughout the day. The main vocals consist of loud, deep guttural growls or “howls.” Howler monkeys are widely considered to be the loudest land animal. Their vocalizations can be heard clearly for 3 miles.
These monkeys are excellent climbers and can use their tails as well as their arms and legs to swing on vines and climb trees. They make their homes high in the tree canopy of the rainforests.
