Why do monkeys scratch each other's backs and eat each other's salt?

Monkeys are fiddling with a secretion, which is generally white and granular, containing salt, trace elements and other substances. Little monkeys are so sweet because they think the food given by the zoo is too light, so they come up with a way to get salt from their companions.

And it is worth mentioning that this kind of behavior similar to catching lice is generally a monkey with a lower status among monkeys. Grasping it by a higher-ranking monkey often means pleasing each other, and the mother monkey will also catch it for the little monkey to express her deep maternal love for the little monkey.

For example, monkeys are good at picking bugs in tree holes or crevices. Orangutans eat a lot and spend most of their time foraging. The stomach of colobus monkeys has a special structure, and most species eat plant food containing a lot of crude fiber.

In the monkey kingdom, there is a unique and strict hierarchy, which is divided into monkey king, two monkey kings (leaders of small societies) and ordinary people. Zoological experts told reporters that the monkey king has supreme power in the monkey group and is mainly responsible for protecting the safety of the monkey group; Second, the Monkey King is equivalent to the prime minister, managing everything in the monkeys. In the world of monkeys, being the monkey king has many advantages. Not only can you eat delicious food first and have fun, but you can also choose a "wife" among monkeys at will. Except the Monkey King, other male monkeys are not allowed to "fall in love".
