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 Magrove 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 Guatgemala 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 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)from water onto land,” Wright said.

危地马拉市(西班牙语:República de Guatemala),(路透社,路透社是世界四大通讯社之一,也是英国创办最早的通讯社)——一项新的研究显示,一条生活在美洲红树林沼泽地的鱼在一次没有水的情况下可以活数月,和数百万年前,动物是如何适应陆地的情况相似.
Magrove Rivulus,一种产于淡水的将科小鱼,它通常生活在特定类型的空螺母中的小水塘中或者伯利兹、美国和巴西的红树林沼泽地里的啤酒罐水中.当它们居住的地方干涸,它们就会居住在陆地圆木上,斯科特?泰勒这样说,他是一名佛罗里达州布瓦拉濒临灭绝的土地计划组的研究员.
那条鱼,其学名是Rivulus marmoratus,能长成三英寸那么大.它们一起生活在圆木上,通过皮肤呼吸空气,直到他们能找到水为止.
去了一趟伯利兹城后有了新的科学发现.
“我们踢翻了一个圆木,鱼都挤了出来.” 泰勒通过电话告诉邻近Guatgemala 的路透社.他说明年初,他会在一家美国的杂志上公布他对这种鱼的研究成果.
通过实验室的试验,泰勒说他发现这种鱼在没有水没有食物的情况下可存活到66天.
其他的鱼在没有水的情况下只能存活一段时间.人们发现东南亚的步行鲶鱼一次可在陆地上呆上几个小时,然而澳大利亚,非洲和南美的肺鱼在没有水的情况下可以存活,但是水只是在非活性状态下.但是目前除了Magrove Rivulus和肺鱼在没有水的情况下可以存活,就没有其他人们所知道的鱼了.帕特里夏?怀特,加拿大大学的一位生物学家的圭尔夫这样认为.
进一步对鱼的研究可以告诉我们动物是怎样随着时间变化的.
“这些动物生活的环境和数百万年前,当动物从海里开始向陆地过渡的环境类似从”赖特说.

该Magrove Rivulus,一小鳉,住在小水池的水在一空型螺母,甚至在伯利兹的红树林沼泽旧啤酒罐某种类型,美国和巴西。当他们的居住地干涸,他们对土地的原木(圆木)生活,斯科特说,泰勒,一个在布里瓦德濒危地政计划在佛罗里达州的研究员。
鱼,其学名是Rivulus鳢,可以长到3英寸的大。他们在一起的原木和呼吸的空气,通过他们的皮肤,直到他们能找到水了。
新的科学发现是继1至伯利兹之旅。
“我们在一个日志和鱼刚刚踢排挤,”泰勒说邻近Guatgemala通过电话对路透。他表示,他将在著名的美国杂志到明年年初公开其研究的鱼类。
在实验室测试中,泰勒说,他发现鱼可以活到66天没有吃出来的水。
一些其他的鱼可以离开水存活了很短的时间内。行走在东南亚发现鲶鱼能在几个小时地停留在时间,而肺鱼在澳大利亚,非洲和南美洲发现可以离开水存活,但只能在一个非活动状态。但是,没有其他已知的鱼可以离开水,只要红树林Rivulus并保持活跃,根据帕特里夏赖特,在加拿大圭尔夫大学的生物学家。
鱼的进一步研究可能会告诉动物如何随着时间而改变。
“这些动物生活在条件类似的那些存在几百万年前,当动物开始从水中到陆地决策的转变(过渡),”赖特说
