Monkeys and apes share many similarities. They are both primates, which are characterized as social animals with large brains and hands that can grasp.
But what’s the difference between a monkey and an ape? How can you tell them apart?
Tails
The easiest way to tell if it’s a monkey or an ape is by the presence of a tail. Monkeys have tails. Apes do not. So if you see a tail, it’s not an ape.
Example: Look at the glorious tails on these guereza colobuses. Ape? No. Monkey? Yes!

See the long tail on this squirrel monkey as it leaps? Ape? No. Monkey? Yes!

Now look at the tail-less butt of this mountain gorilla. Ape? Yes.

But wait! Some monkeys have teeny tiny stubs of tails that you can’t see.
Look at the butts of these Japanese macaques. Tail? Doesn’t look like it. But is it a monkey? Yes!

So in certain cases where you can’t see a tail, it may be tricky to tell if it’s a monkey or an ape. But there are other distinguishing factors as well.
Size
Apes are generally larger than monkeys and have broader chests.

Location
Apes live in Africa and Asia. Monkeys live in Africa and Asia too, but they also live in Mexico, Central America and South America. No apes live in the Americas.
Example: This spider monkey is native to Central America and South America. Monkey? Yes.

Intelligence
Both monkeys and apes are intelligent, but apes have a larger brain-to-body ratio and have even greater intelligence. In fact, some apes can even communicate in human sign language!
Example: Apes, like this chimpanzee, are very sophisticated tool users, which is a sign of high intelligence. But it should be noted that there are also a few monkeys who use tools as well.

Memorize the Different Kinds of Apes
If all else fails, you could actually just memorize the different kinds of apes because there aren’t that many.
The different kinds of apes are:
Humans
Bonobos / Chimpanzees
Orangutans
Gorillas
Gibbons
So then if it’s an animal within that group, you know it’s an ape!
Lincoln Park Zoo in Chicago is excited to announce the birth of a Japanese macaque (pronounced muh-‘kak), also known as a snow monkey, born on May 2.
Zoo staff has determined the little baby is a male. He and his mother Ono are doing well.
According to Curator of Primates Maureen Leahy, “The baby appears healthy, is regularly nursing and visually exploring the exhibit while clinging tightly on Ono’s torso.”
He joins a troop of eight snow monkeys at Regenstein Macaque Forest, the newest exhibit at Lincoln Park Zoo. The expansive exhibit includes microclimates, a hot spring, stream and various levels, creating an ideal environment for the growing snow monkey population.
“From a research perspective, this is a significant addition to the population,” said Research Scientist Katie Cronin, PhD. “The new baby will be the first in this population to grow up with access to touch screen computers – a tool that the monkey can decide whether or not to use – so that we can study cognitive abilities and gain a better understanding of how they think and feel.”
In the wild, Japanese macaques inhabit extreme climates throughout most of Japan, from sub-tropical lowlands to sub-alpine regions. Learn more at snowmonkeys.org.
