In addition to using their high-pitched clicks for communication, toothed whales can use a technique known as echolocation, which allows the whale to bounce sounds off of objects in the environment and gain information from the echo that returns to them, such as the distance of an object, how fast its moving, what direction its in, how large it is and whether its a dense or hollow object.
