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 Austra lia, Africa and South America can live ont 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) from water onto land, ”Wright said.

“Old wives’tales” are beliefs passed down from one generation to another. For example，most of us remember our parents’ telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking，but others have not passed the test of time.

Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic(蒜)is good for you，too. It can kill the type of virus that causes colds.

Unfortunately, not all of Mom’s advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems？Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars.

Even though science can tell us that some of our traditional beliefs don’t hold_water,_there is still a lot of truth in the old wives’ tales. After all, much of this knowledge has been accumulated (积累) from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false.
