Use water for example

The primates at Trinity University (USA) are studying a strange habit of Capuchin monkeys about male use of urine seducing females.

Capuchin Monkey lives in Central and South America. Earlier, many hypotheses suggested that male monkeys using rubbing urine to maintain their body temperature or to distinguish animals in the herd.

However, in a recent study, scientists discovered Capuchin's monkey brain which was more flexible when it smelled of adult male monkey urine. Male monkeys excrete a lot of male hormones in the urine and this hormone level also increases if it has a better position in the herd. Therefore, instead of using conventional methods, Capuchin males used urine to signal that it was lonely and attracted females.

According to scientists, this is a form of communication to express strange sex in monkeys because most animals do not know how to communicate with odor signals.
