How do Dolphins communicate?

There are a lot of people who have always been interested to know how dolphins communicate with each other. They are very smart creatures, and they are known to interact with each other in different ways. For example, they can create sounds that will allow other dolphins to know that they are nearby. There are even instances when they use sounds in order to interact with human beings.

When they are underwater, they may communicate with the use of echolocation. They use their flippers to create movements that will be felt by other dolphins that are miles away. Some of their methods of communicating still have not been deciphered by humans.
