Dolphins are interesting animals. Working with them is fun, because you never know what they will come up with to surprise you.

Reiss was training Circe to "stay at station" in front of her. Every time the dolphin swam off, Reiss gave her a time-out by backing away from the side of the pool and standing at a distance. When Circe stayed, Reiss fed her a piece of fish. But then she gave her a piece with fins by mistake.
Circe looked at Reiss, spat(吐) out the fish, and swam across the pool. She took an upright position in the water and simple "stood" there. Circe was communicating (交流) loud and clear. "I felt as if I had gotten the time-out! " says Reiss.

Interesting as dolphins (海豚) are to scientists, it is their intelligence and sociability that have caught the popular imagination. Like whales, dolphins have a strong sense of family. A dolphin family is like a human family, but much larger.
Dolphins seem to be among the most sociable of all living creatures. They enjoy playing with each other and also with the humans, with whom they come in touch. It is this characteristic that makes them so easy to train as star performers. Besides, they seem able to remember humans that they have met even when there is a long period of time between meeting.
A sense of family and a spirit of cooperation appear to be very strong among all these marine animals. There are many recorded cases of dolphins supporting a sick animal on the surface of the water so that it will be able to breathe.
Language has always been considered unique to human beings. It now seems that the cetaceans (鲸目动物) may be able to communicate with each

Irish scientists monitoring dolphins living in a river estuary in the southwest of the country believe they may have developed a unique dialect to communicate with each other.
The Shannon Dolphin and Wildlife Foundation (SDWF) has been studying a group of up to 120 bottle-nose dolphins in the River Shannon using vocalizations collected on a computer in a cow shed near the River Shannon.
As part of a research project, student Ronan Hickey digitized and analyzed a total of 1,882 whistles from the Irish dolphins and those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories. Of the categories, he found most were used by both sets of dolphins but eight were only heard from the Irish dolphins.
"We are building up a catalogue of the different whistle types they use and trying to associate them with behavior like foraging, r

[单项选择]Dolphins have the power to make people feel better just by their presence, according to a leading marine biologist.
"I cannot explain it in scientific terms but, without any doubt, everyone who sees them in the wild is lifted by them," Jonathan Gordon, of Oxford University zoology department, said.
"You only ever see them in the wild if they want you to see them. They are the only wild animal that comes to man of their own free will and that makes you feel privileged. You get a buzz because they are joyful, and you can prove scientifically that they spend a lot of their life playing. "
Professor Gordon works for the International Fund for Animal Welfare and spends months on the organization’s research boat~ "If things aren’t going well on the boat and you are depressed, the sight of dolphins lifts you and makes you feel better at once. They cannot be doing this on purpose, but I can believe that people who are intensely depressed or suffering from some kind of mental blo
