Both species are appropriately named ​ — spider monkeys because they are all arms and legs and howler monkeys because they make a loud crying sound that can be heard up to two miles [3 km] away!
Kedua spesies itu cocok dijuluki demikian ​ — monyet labah - labah karena lengan dan kakinya panjang - panjang dan monyet pelolong karena teriakan mereka yang keras bisa kedengaran sampai sejauh tiga kilometer!
