How to reference this medium
Description:
Just like a bat, a dolphin can recognize from the echo whether the prey is nearby or not. It produces clicks and whistling noises under water. If it has discovered something of interest, the dolphin will move closer and "click" more quickly. This gives it an exact acoustical picture of its surroundings.

Information and ideas:
Based on the phenomenon of an echo, this graphic can show how animals use the echo to find prey.
