Howler monkeys are the loudest land animals, with their calls reaching up to 130 decibels.
Their howls can be heard up to 3 miles (4.8 kilometers) through dense forest.
They have a specialized hyoid bone that amplifies their vocalizations.
Howler monkeys spend up to 80% of their time resting, making them one of the least active monkey species.
They possess prehensile tails, which act as a fifth limb to grasp branches.
Howler monkeys live in social groups called troops, typically consisting of 6 to 15 individuals.
