CGUATEMALA 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.49.

EXTENDED FAMILY In an extended family, all the people share one household. Apart from parents and children, there may be other family members grandparents, aunts, uncles, cousins, etc. That is to say, a large family may have more than two generations, and often there are more than two adults from different generations of a family. The family members live together for many reasons. They may help to bring up children or to take care of an ill relative. They may also help with saving money. Sometimes children are brought up by their grandparents, for their parents have died or can never take care of them. Many grandparents look after the children,particularly when both parents are busy working. This large family is called extended family. It can be found all over the world.
