Description:
The vocal sounds of cetaceans are a little known and even less understood
feature of the complex adaptation of these animals, whose ancestors
lived on the dry land, to an entirely aquatic existence. Even in the clearest
surface waters, sight is limited to about a hundred feet or less in daytime,
and visibility ranges are mostly negligibly short for fast-swimming
animals, so that they are effectively partly or wholly blinded. Therefore
sound and hearing have an especially important place in their lives. Sound
is used not only in direct communication, but also to a large degree in
navigation and hunting (echo-location). The excerpts presented here are
samples of such sounds made by eighteen species, all obtained by eavesdropping
in the open sea (except for the Inia selection, which was made
in captivity). These recordings have not been speeded up or slowed down,
and so are true in natural frequency and time; there has been no editing or
filtering except as noted.
