How do whales and dophins communicate?

Answer 1

Whales and dolphins use echolocation the noises they make that seem to vibrate (or send echoes). They use the echo from this noise (some refer to it as a sort of song) to find out the size, location ex. of other objects, or other mammals in this case within close proximity of their location. Different types of whales and dolphins use different variations of echolocation, but this can help other mammals determine their species. Dolphins have many other ways of communication, such as touch, body language ex. Some even believe that dolphins have a way of understanding humans.
