BLACK HOWLER
Alouatta caraya
DESCRIPTION
The Black Howler (Alouatta caraya) is a medium-sized primate known for its distinctive black fur and loud vocalizations. Males are typically larger than females and possess a throat sac that amplifies their calls, which can be heard over long distances. They are arboreal and primarily inhabit the canopy of forests, where they move gracefully among the branches.
FUN FACTS
- Black Howlers are known for their impressive vocal abilities, with their howls being among the loudest of any land mammal, reaching up to 90 decibels
- This vocalization not only serves to communicate with other howlers but also plays a crucial role in maintaining social bonds within their groups
- | These primates have a unique adaptation that allows them to digest tough leaves, which are often low in calories
- Their slow metabolism and specialized gut help them extract the necessary nutrients, making them well-suited for their folivorous diet
