Dolphin Talk

Bottle-nose dolphins may lack vocal cords, but that doesn’t stop them from communicating. They emit a variety of whistles and squeaks through their blowholes and each dolphin has a signature sound that identifies him to others. Dolphins may mimic another's sound to get its attention, a bit like calling out its name. It is not yet known if they have a formal language, but researchers have observed them using communication sounds during group hunts and mothers and offspring use their sounds to locate one another, if they become separated.
