Frogs Who Has Long Vanished

A number of amphibian species status of the mysterious. They have not declared extinct, but also did not reveal its existence for decades. Some biologists carry out scientific expeditions to search for amphibian species are "lost" it, for example in the Congo. 

Having traveled for two years since 2009, scientists discovered five types of frogs which are all unique. The existence of the frogs that actually have been described since 1950, but they seemed to hide themselves from humans. 


Hyperolius leucotaenius 
One type of frog found in the Hyperolius leucotaenius. This frog has a transparent skin so that internal organs and even eggs could be seen. This frog species found in Elila River, southeastern Congo. 

Hyperolius leucotaenius has a green head and body-colored transparent plastic tub. This frog also has a pattern of yellow lines and tip-toe orange. Not yet clear reason why this frog has a transparent body. 

In addition, there are three species found in highland areas Itombwe, southeastern Congo. Two of them are Chrysobatrachus cupreonitens who have a body color of green and brown and Phrynobatrachus asper which have thick fleshy foot. 


Chrysobatrachus cupreonitens 


Phrynobatrachus asper 
Asper Phrynobatrachus species discovery is unique. This species was rediscovered in 2009 when a villager in the highlands of Itombwe offer dinner made from the frog to the scientists. 


Arthroleptis pyrrhoscelis 
One species from the highlands again Itombwe is fingered frog nail or Arthroleptis pyrrhoscelis. The development of the frog is unique because not pass tadpole phase. While the latter is Hyperolius chrysogaster species, found in the Kahuzi-Biega National Park, eastern Congo.

Expedition rediscovery of the lost amphibians is led by El Greenbaum, biologist at the University of Texas at El Paso. The expedition was funded partially by the research committee and exploration, National Geographic Society. 

"The discovery of my team to prove that the forests were (in Congo) is still unexplored. There are a lot of biodiversity in there and not too late to redouble our efforts in conservation," said Greenbaum.
