Fun Facts: Dolphins communicate verbally, with squeaks and whistles; these sounds create echoes that help them to find their food underwater. The sounds travel underwater until they hit an object, then they bounce back and this lets the dolphin know where their prey is, how large it is and its shape. This is called echolocation.
