Monkey hid peanuts in his mouth and then spit it out and ate it alone

We often see when monkeys eat, they put food in their mouth very quickly. When food enters the mouth, they do not immediately swallow the stomach. In the two sides of the monkey's oral cavity there is a pouch, called a rump, located under the monkey's chin. The function of this hump is mainly to hide food, like ruminant cattle.
