Communication between animals

This video reflects the communication between animals. Animal communication refers to the transmission between one or a group of animals (the sender) and one or more animals (the receiver), which can change the current or future behavior of the receiver.
Information transmission can be intentional, such as courtship performance, or unintentional, such as a hunter sniffing the scent of prey. The same information can be transmitted to several different recipients.
If the sender changes the behavior of a receiver, the message is called "signal". According to the signal theory, if a signal is to continue to exist in the population, its sender and receiver should generally benefit from information transmission.
