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’s easy to see how the sawfish got its name. These frightful creatures can grow to be more than 6 meters long. Their bodies are flat and winged, like underwater airplanes. And their noses are shaped like chainsaws.
Sawfish are food hunters of the sea. When a sawfish is hungry, it waves its sharp-toothed snout（口鼻部）through a group of fish. Then, it lifts its nose and uses its mouth to draw the injured victims.
Hardy（适应力强的）population of sawfish thrived in warm waters along coastlines around the world for thousands of years. Over the past 200 years, however, human actions have severely endangered sawfish. Threats include fishing nets that trap the huge animals, often by mistake.
Some people collect sawfish’s snouts as prizes: One snout recently sold for nearly $ 1,600 online. In some Asian cultures, the toothy snouts are used in ceremonies to drive evil and disease away. And sawfish are also delicious. A growing demand in Asia for the fish’s fins for a pricey soup has contributed to the fish’s loves. Compared with other fish, sawfish give birth late in life and at slow rates, which makes it hard for them to recover from overfishing.
New efforts now aim to restore sawfish population. Beginning next month, an international agreement will provide protection for all seven of the world’s sawfish species. Scientists are hoping that it’s not too late to save the sawfish.
Until 1998, “this fish had never been formally studied in the United States,” says Tonya Wiley of the Mote Marine Laboratory in Sarasota, Fla. “We didn’t know such basic things as where they live, what habitat they use, how often they breed, how many young they have — even what age sawfish are when they begin breeding.”
Through historical studies and field research, scientists have become aware of how much the fish’s numbers have decreased. Today, there may be 90 percent fewer sawfish than there used to be. Wiley estimates that only 3,000 to 6,000 sawfish remain in US waters.

The beggar’s well-deserved dinner
Many years ago, there lived two woodcutters, Rahim and Rahman in a village. They went out every 36 to cut fire wood. After cutting wood. They would sit down and 37 their lunch from their boxes. Next they would 38 the firewood till the end of the day in the marketplace before going 39 .
One day, they were eating their lunch when Rahim noticed a beggar. The beggar 40 eyed the lunch and said, “I wonder if you can spare a little food for me.” Rahim, who felt 41 for him, was about to give him some of it, but was 42 back by Rahman. “ We 43 hard throughout the morning and 44 enough food for ourselves to see us through the 45 . So you see we cannot give you any food. But if you 46 , I can lend you my axe and we both will teach you how to cut firewood and sell it. And you’ll have 47 to eat and buy yourself a(n) 48 axe to cut more fire wood. This way, you can 49 a livelihood with dignity (尊严).”
The beggar joined them. 50 , Rahman showed him how to cut firewood. Thereafter they took him to the 51 and told him how to sell it.
At the end of the day, the beggar proudly took the 52 to Rahman to show them his earnings. Rahman took him to buy a new axe. Then the beggar entered an inn (客栈).
After he had gone, Rahman told Rahim, “By teaching him how to 53 his own trade, we have taught him a skill, which will last him a 54 . Now he will hever go hungry again.” As a very famous saying goes, “Don’t give them fish 55 teach them how to catch the fish.”
