How does Echolocation work in Dolphins?

1. The dolphin creates clicks in its nasal sac.
2. A round organ called the melon focuses the sound beam.
3. The sound strikes an object and returns toward the dolphin.
4. The panbone in the dolphin’s jaw receives the echo; fatty tissue behind it transmits the sound to the middle ear and from there to the brain.
5. Continuously transmitting and receiving clicks, the dolphin reacts to the time lapse and strength of the signal to judge distance and home in on an object.


1. SENDING: A dolphin squeaks, sending out sound waves through the water.
2. The waves bounce off an object and echo back to the dolphin.
3. RECIEVING: The time it takes for the echo to reach the dolphin tells the dolphin the location of the object.
4. The way the sound echoes tells the dolphin the shape,size,and speed of the object.
