Howler monkeys are New World monkeys, which live in the Americas. An enlarged hyoid bone at the root of the tongue gives the throat a swollen appearance. Males are larger and have a darker and heavier beard. The prehensile tail can measure up to 31 inches 79 cm and is without fur on the bottom side of the last third, which allows for better grip when grabbing branches. Size : One of the larger species of neotropical primates, Red howlers are the largest of the howler monkeys.

Females are inches cm long; males are inches cm. Males can weigh up to 20 pounds 9 kg while females rarely exceed 15 pounds 7 kg. Behavior : Red howlers live in social groups of not more than ten members, with one or two of the individuals being males. They are rather inactive monkeys, and usually have small territories in which they do little more than sleep and eat.

Females may also contribute with their higher pitched sounds.
