People want to know how fish can hear sounds without ears.But fish do have ears.We cannot see the ears because they are inside their bodies,and they hear very well with them.Their listening is much better than man's.
Many water animals make noises while they are doing something.Sounds are real words of them.By sounds,they know where they are and which way to go.When they face danger or they find food,they always make sounds to tell others the good news.
A new field in science is to learn the meanings of underwater sounds.People use the same skill that they have used in learning the secrets of birds' calls.But this method is more difficult to use in the sea because many of the sea animals cannot be easily followed and studied.We have not any other way to study the sounds in the sea.Perhaps the meaning of the calls of the sea animals will be known more clearly someday.It will be useful for us to learn the ,secrets of the sounds in the sea.
