    Here is a story of the Baiji River Dolphin. It makes its home in the Changjiang River. Over 20 million years ago,the Baiji River Dolphin left the sea,swam up the Changjiang River and has lived there ever since. It has smaller eyes than other kindvS of dolphins because the Changjiang River has many small pieces of earth in it. The small size helps to protect its eyes. However,because it has such small eyes,it can not use its eyes to find food. Instead,this kind of dolphin uses sound waves (聲波) to find food. This makes it so unusual.
