答案
Animal Chatter Among the most unusual and varied sounds on earth are those made by animals. Monkeys chatter and shriek, birds chirrup and squawk, and bullfrogs produce an amazingly loud noise to attract mates and drive away other males during the breeding season. Most animal sounds, like those of the bullfrog, serve as a form of communication. They may warn, attract, or help an individual to identify others nearby. Whales and dolphins produce an especially complex variety of sounds. So much so that scientists have suggested they may have an advanced language of their own. What is certain is that these creatures can call to one another with sounds that are both below and above the range of human hearing. Dolphins seem to have another use for the ultrasonic "clicks" they are capable of producing. With a powerful, narrow beam of ultrasound they can stun a fish and then grab it in their jaws before it has a chance to recover.
