    How whales hear has been studied but some info is still needed.
    > How whales hear?
    Research indicates that toothed whales hear sounds with their lower jaws.
    The lower jaws are basically hollow, filled with a fatty substance that
    transmits sound and has very thin areas called acoustic windows.

    Toothed whales makes the clicks in a portion of their head between the
    double nostils in the skull and the external blowhole on the head. The
    sounds are focused with a fatty tissue, the melon, in the forehead area.

    There are a lot of files on sound in areas of WhaleNet. Use the WhaleNet
    Search and type in "sound."
