Dolphin and Whale communication

I have always been interested in the ways in which dolphins communicate. I spent some time looking into this topic to try and learn more about their communication methods. Dolphins and whales have similar forms of communication. They both create sounds, make physical contact and use body language. They also use echolocation, as a way to navigate underwater. This sense also allows them to hunt efficiently. The way echolocation works is incredibly interesting. They use sound waves that bounce off other objects to get an understanding of their surroundings. The waves that bounce off lets them build an image in their mind of what they are looking out. Dolphins have a more advanced form of echolocation which gives them the ability to hunt in murky water or find food under the sand.
