GUATEMALA CITY(Reuters)---- A fish that lives in mangrove swamps(红树沼泽)across the Americas can live out of water for months at a time, similar to how animals adapted(适应)to land millions of years ago, a new study shows.
The Mangrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida .
The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡)form water onto land, ” Wright said.

It is sometimes reported that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified(不明的)Flying Objects(UFOs). These UFOs caused a lot of interest.

“It wasn't the moon,”was the reply.
They watched the light and saw that it was moving.It seemed to be an object rather like a big plate.In some ways it looked like smoke with a light on it,but it wasn't smoke because it didn't change its shape.It was moving in a regular way.That is to say,it didn't go suddenly faster or more slowly,and it didn't go higher or lower.So the two men decided that there must be men in it.
When it came nearer to Libya,Bardens said that he felt eyes looking at him.He was being watched in the darkness.
When it was nearer,they noticed that the bottom parts were brighter than the top.The bottom was yellow and the top was red.Then the object suddenly turned away and left Libya,moving very fast.

Toyota Motor Corp, Japan’s biggest carmaker, said on Friday it will recall 1,489 Lexus sedans (高级轿车) sold in China.

A press report stating that Microsoft has restarted talks to buy Yahoo's search business for 20 billion U. S. dollars. "It has no basis in fact," the San Francisco Chronicle said on Monday.
The Times of London reported on Sunday that the deal under discussion would put former AOL CEO Jonathan Miller and Ross Levinsohn, a former president of Fox Interactive Media, in charge of Yahoo. The report also said executives (管理人员) at both companies had agreed to the broad terms of a deal.
In fact, there are no current talks between the two companies. The Chronicle quoted an executive at one of the firms who requested his name to be kept secret as saying. Furthermore, the 20-billion-dollar price mentioned in the Times of London article for Yahoo's search business appears questionable given that the market capitalization (资本总额) for all of Yahoo is 16 billion dollars, said The Chronicle.
Yahoo and Microsoft had had on-again, off-again talks over several months earlier this year about a 47. 5-billion-dollar takeover, and later a proposal focused only on Yahoo's search business. Discussions regarding both plans collapsed without an agreement.
Microsoft CEO Steve Ballmer has said repeatedly that he is no longer interested in buying all of Yahoo, but that he is open to some sort of partnership involving their respective search businesses.
Brad Williams, a Yahoo spokesman, said Sunday "We don't comment on rumors." Frank Shaw, a Microsoft spokesman, declined to comment.
Yahoo's shares have plummeted since Microsoft withdrew its 33-dollar-a-share acquisition offer earlier this year, leaving people to think that discussions would eventually be restarted. Yahoo's shares closed Friday at 11. 51 dollars, nearly one-third of the original offer.
