Smallest Monkeys:
* Pygmy Marmoset: The smallest monkey species, measuring about 5-6 inches in length (excluding the tail) and weighing just a few ounces.
Largest Monkeys:
* Mandrill: The largest monkey species, males can reach up to 3 feet in length and weigh up to 80 pounds.
* Western Lowland Gorilla: While technically classified as apes, gorillas are often considered the largest primates and can reach up to 6 feet tall and weigh over 400 pounds.
Other Factors:
* Diet: Monkeys that primarily eat fruit tend to be smaller than those who eat more leaves and vegetation.
* Habitat: Monkeys living in forests often have different body sizes than those living in grasslands or open areas.
Important Note:
While the mandrill is considered the largest monkey, some primate species, like gorillas and orangutans, are even larger. However, these are classified as apes, not monkeys.
