After a long period of studies, scientists are uncovering surprising new findings about dolphins.
They believe that dolphins do \"talk\" to each other, whistling \"names\" among themselves and others in their group. They help one another when in trouble. Like bats, they use sound waves to \"see\". Because of these and many other findings, many scientists now place dolphins among the cleverest animals on earth.
Dolphins love to mimic. If we swim on our backs, they do too. If we dive, they follow. Once a trainer blew a puff of cigarette smoke against the window of an observation tank, a young dolphin suddenly swam to its mother, nursed a moment, and spit out a cloud of milk against the glass. It is even more surprising that dolphins are able to understand sign language. One of Herman's dolphins has mastered more than 50 sign words. For example, it understands the difference between \"bring the surfboard to the person\" and \"bring the person to the surfboard\".
Scientists are learning how dolphins \"speak\" to each other. \"Each dolphin\\"has its own 'signature' whistle.\" Dolphins can also mimic the signatures of others. Dolphins help one another. When birth-giving takes place, females gather to keep off sharks. Later, while the mother looks for food, they take care of the young dolphin, swimming in a circle.
