Dolphin echolocation. Computer illustration showing how a dolphin uses sound waves to locate prey and navigate underwater. The dolphin emits supersonic sounds, which are focused in front of it by an organ called the melon (yellow). Sound waves reflected by an object are absorbed by the dolphin's fatty jaw and channeled to the auditory bulla (orange), which transmits the resultant nerve signals to the brain. The sounds are then used to build a picture of the object and its location. | |
