Bottlenose dolphins communicate through several kinds of whistles, squeals, clicks, and other sounds.

They can even send identity information through such noises, and the amount of data sent is still unknown to scientists.

What is already known is that these whistles are used to coordinate the pod when hunting, making feeding easier and more efficient for them.

Some research concluded that dolphins transmit cultural knowledge to their offspring for surviving and they teach it through the different kinds of communications that dolphins use.

They also use the burst-pulsed sounds to communicate.
