Dolphins
are extremely and almost continually vocal. Dolphins are capable of two
different types of sounds. One of these sounds is the short pulse type
sound emitted by a specialized  mechanism in the nasal passages just below
the blow hole. Sounds called clicks can be produced in such a rapid
succession as to resemble a buzz or even a duck like quack. Clicks are
used as a form of sonar in which echoes of sounds from surrounding objects
enable the dolphins to detect obstacles, other dolphins, fish, and even
tiny bits of matter in the water. This term is called echolocation, and
this is found only in a few other animal groups, most notably the insect
eating bats. |
