　　参考阅读： Fish Communication Can fish "talk?" And if they do, can other fish
hear what they are saying? The answer to both questions is yes, but fish "talk"
and "hear" somewhat differently than humans. Although not extremely common,
there are several species of fish that are able to produce sound to communicate
with members of their own and other species. Most of the fish that produce sound
do it at such low frequencies that divers cannot hear the noises. But several
species do produce sound in the range that humans can hear. For example, grunts
are able to produce sound by grinding their flat teeth together (hence the name
grant!) The large Jewfish, Nassau and Black groupers are known to make very loud
"booms" when startled or cornered. Jewfish have also been observed to make these
loud
