What has a face like a koala, fur like a zebra and is small enough to fit in the pocket? The answer: Maues marmoset (mah-WAYS MAR-mah-SET).
Sounds like monkey business? Well, it is! A marmoset is a monkey. And scientists recently found a new type of marmoset near the Maues River in the Amazon rain forest. It's the third new monkey discovered in Brazil since 1990.
So far, scientists don't know much about the pocket-sized monkey. But one thing they do know is lots of undiscovered plants and animals exist. (Of the millions of possible species, only 1.4 million are known.)
So who knows? There could be many more monkeys out there monkeying around.
