We just learned about the Black Bearded Saki.
Another type of new world monkey is the Mantled Howler or golden-mantled howling monkey.
These monkeys live in Central and South America.
They have mostly black fur and the grow to be about 22 pounds and about 2 feet long.
Just like you would think from the name, they make a loud sound, that is usually like a low grunting sound almost like a dog barking or a pig grunting.
It can be heard in the jungle from miles away.
