For example:
Action:
1 The back of a deer's small tail is white. When they are in danger, they will raise their tails to show the opposite white, just like waving a white "signal flag" to tell their companions: danger, run!
When bees find the honey source, they will tell their companions the distance and direction of the honey source through the round dance and the "8" tail dance.
After human training, an orangutan can master hundreds of words expressed by gestures and have a simple conversation with people.
Smell:
1 A female moth can secrete 0. 1 microgram of sex hormone before mating and laying eggs, but the male moth can receive this signal even from the distance of 1000 meters by relying on the antenna of the head, and immediately come to meet her.
When the queen bee leaves the original hive and goes to another place, she will secrete an aggregation hormone, which will make the separated bees gather around her and soon form a new colony.
When ants go out to look for things, they can use their own tracking hormones to mark the route and guide their companions to find the location of food.
When aphids find natural enemies such as ladybugs, they will immediately secrete warning hormones to warn other companions not to ask to come, so as not to be eaten.
Voice:
According to zoologists, pigs have 23 kinds of sound signals; Foxes have 36 kinds of sound signals; There are no fewer than 40 kinds of sound signals from Arabian baboons. As far as the ability to imitate sounds is concerned, a parrot named Coonia can "speak" hundreds of words and dozens of sentences!
