Man is the most intelligent animal created by God because God has given him language which other animals do not have. Communication makes life extremely convenient and easy. Language plays a very important role in life as any emotion can be easily and effectively conveyed (传递) through language to anyone. But all this is applicable and beneficial only to human beings. What about animals? How do they communicate with each other?
We all know that animals do not have the ability to use language as a medium for communication. But they do have other means of conveying messages to other animals, of which use of body language is the most important one. The messages can be of many types like conveying food location, danger alarms, appreciation of good deeds like helping other animals in dangerous situations, etc. There are two main types of communication in animals: verbal (语言的) communication and non-verbal communication.
Sound is one of the most common types of verbal communication in animals, and majority of the species use it as the medium to convey messages. Bats have to rely on sound waves to communicate. They mostly rest in the morning and become active at night to search for food and do other tasks. All the birds communicate through their chirping. Mammals generally make use of sounds to give calls to other members of their community. Whales are the perfect examples, which use sound waves for communication. They have a whale song, which they repeat after regular intervals.
Facial Expressions
This kind of communication is mostly found in dogs. When they are angry, they show their teeth and raise their ears. On the other hand, when they are frightened, they pull their ears behind and open their mouth. Also, in birds, when the parent bird brings food for the offspring, the begging expression can be observed on the offspring’s face.
Gestures and Body Movements
This type of communication is common not only in animals, but in human beings too. All human beings, although they use language for communication, tend to use gestures and body movements as well while communicating. Honey bees are the most enthusiastic creatures on earth because they dance to communicate. Some bees dance in the hive (蜂箱) so that other bees get signals of the location of the honey comb. A deer waves its tail to warn others of coming danger.
