Dolphins have  a series of different ways of communicating.  They actually have no vocal cords, but they do generate a complicated series of whistles, squeaks, moans, trills, and clicks.  These sounds are produced from the sphincter muscles within the blow hole.

The main way they communicate is called echolocation.  What is echolocation?  It is a type of communication that sends waves to objects ahead, then the waves bounce back to the dolphin, letting it know if there is a pod of fish or another animal positioned around the dolphin. These sound waves are picked up by the dolphin’s bulbous forehead.  Even though dolphins can still see at night, this sound system is mainly used then, when the water is sandy and dark.

Some people think that body language is a type of communication.  The first type is visual communication.  This type includes an arch, eye white display, flex, head wag, and play dead.  The second type is touch communication, including bite, hold hands, and push.

For many, many years scientists have been researching the body language and echolocation of dolphins and it seems that dolphins have a language of their own.  They just don’t seem to want to share it with us anytime soon.
