在动物园里,我们有时会看到群居的猴子互相翻开同伴的皮毛仔细寻找着什么,要是找到了,它们就把这好东西往嘴里送。看到这种情景,人们经常说猴子在给同伴捉虱子,真是这样的吗?其实,这样的说法是不正确的。科学家发现,猴子身上并没有什么寄生虫,当然也就不会有虱子存活。但是,猴子为什么要在同伴的皮毛里翻来翻去呢?事实上,它们这样做,是在找一种结晶盐。猴子身上有时出汗,汗蒸发后,皮肤表皮会留下一种略带咸味的结晶盐。它们特别喜欢吃结晶盐,而吃结晶盐是它们补充体内盐分的一种方式。当然,结晶盐长期附着在猴子身上也让它们很不舒服,所以,就出现了猴子互相翻对方 In the zoo, we sometimes see the swarms of swaddled monkeys looking at each other’s fur, and if they find it, they send it to their mouth. To see this scenario, people often say that monkeys are being licked by their peers. Is that true? In fact, such a statement is not correct. Scientists have found that monkeys do not have any parasites and, of course, no lice survive. However, why did the monkeys turn around in the companion’s fur? In fact, they did something to find a crystalline salt. Sometimes the monkey sweats, sweat evaporates, the skin epidermis will leave a slightly salty crystalline salt. They particularly like to eat crystalline salts, and eating crystalline salts is their way of supplementing the body’s salt. Of course, the long-term attachment of crystalline salts to the monkeys also makes them uncomfortable, so it appears that the monkeys turn over to each other
