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.

危地马拉市路透社电------一项新的研究发现：在美洲各地的红树沼泽水中生活着一种在一段时间内数月离水还能存活下来的鱼，其生存力之强一如数百万年前动物适应大陆的情形。

此鱼俗名红树溪鳉属将科小鱼，产于贝利兹、美国和巴西红树沼泽的小水潭中，在水中某些果实的空壳内甚至在旧啤酒罐内它也能生活。佛罗里达州Brevard濒危地带管理署的研究员Scott Taylor说，红树溪鳉在其水域干枯后也能继续在陆地上的圆木丛中生存下来。

此鱼学名为红树鲉，长成全长能达三英寸，他们成群生活在圆木丛中，依靠皮肤呼吸空气直至再找到水源。这一科学新发现是由Taylor旅行到贝利兹之后取得的。
“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.
Taylor在靠近危地马拉市的地方打电话告诉路透社：“我们在踢翻一根圆木之后，发现那条鱼挤了出来”。他说，他将对鱼进行研究之后在明年初的一家美国杂志上把研究结果公布于众。
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 liveout of water, but only in an inactive state. But no other known fish can be out of water as long as theMangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
在实验室历经数次检测之后，Taylor发现，这种鱼在离开水、不进食的情况下，能存活长达66天。其他一些鱼只能在脱水之后存活一小段时间。在东南亚发现的花虱能一次呆在泥中数小时；而在澳大利亚和南美发现的肺鱼只能在离水后保持静态才能存活小段时间。但是，据加拿大Guelph.大学的生物学家Patricia Wright说，还没有已知的鱼脱离水后存活期能像红树溪鳉那样长久。
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.
对这种鱼作进一步研究的结果也许能告须我们动物的漫长演化方式。这些动物的生存状况和数百万年前的动物相类似，当时动物的栖息地开始从水域向陆地转移。
