Tropical Fish Mangrove Rivulus 800px to itself on the ground
RESEARCH U.S. scientists said the tropical fish that live in the swamps were able to survive for months without water. One type is the mangrove Rivulus fish (Rivulus marmoratus) that live in swamps berbakau throughout the Americas.
Once a bad season arrives and the water shrink, not rare fish that can only grow to the size of 7.5 cm was stuck in a tree cavity made of insects, shells, and even tin cans. They live huddled in a hole the ground and breathe using gills than the skin.
Unlike most fish breathe with gills, mangrove Rivulus skin breathe. When the habitat begins to dry, they hide in the soil pits, coconut shells or even canned beverages. In hiding, the fish skin to breathe and can live for months without water. After the rains came and water re-flooded habitat, they come out of hiding and live like ordinary fish.
Scott Taylor, a researcher of the Environment Endangered Land Program Brevard area in Florida, USA, without knowing accidentally while doing research in Belize, Central America. The actual type of tropical fish can also be found in Brazil and the United States.
"We take apart a tree trunk and the fish come out of nowhere," said Taylor. Then the results of testing done in the laboratory showed the fish to survive up to more than 66 days without water and food. Surprisingly, the body's metabolic system remains functioning normally.
Numerous species of fish known to have the ability to survive without water and food but no one so far. Let's see, catfish that can crawl on land for hours. Lung fish in Australia, Africa, and South America can live without water but only during the period of dormancy (fasting in summer).
The ability of fish may provide clues to how animals began to grow in the ground water. Patricia Wright, a biologist from the University of Guelph, Canada, said the fish habitat is similar to the environmental conditions of millions of years ago when the animals begin to migrate from water to land.
Not only survive without water, mangrove Rivulus fish also has a bizarre sexual condition. Each fish has testicular and ovarian parthenogenetic alias so that it can perform independently with a mate to fertilize their own eggs inside the body. "He is probably the most stable fish, not only has sex odd but also does not have a standard life like other fish," said Taylor.
