Discover the orange crocodiles, unique in the world

In Gabon known for its geological diversity and its fauna, the scientists took the great surprise to discover orange crocodiles, unique in the world, living among bat droppings in the caves.

"When I approached with my flashlight in the cave, I saw red eyes … crocodile in 2008. Two years later, we released a first specimen of the cave and we realized that it was orange ", remember the geoarchaeologist, specialist in archaeological sediments, Richard Oslisly.

A double discovery extraordinary, while he and a team of investigators were trying to find remains of human presence in the caves of Abanda, south of Gabon

The " Caveman Orange Crocodile ", which can measure up to 1.70 meters, is unique in the world and has only been seen in the caves of the African country, according to Oslisly.

"Al principle we think that the smell could be due to their diet, since we found that these reptiles eat bats orange," says the French researcher.

<p>  But after more detailed studies, scientists have presented other hypotheses: "<strong> depigmentation </strong>" caused by the lack of light in these caves or the harmfulness of "guano" , a substance made up of bat droppings in which these animals move throughout their underground life </p>
<p>  "The urine of bats began to attack their skin and transform their color," explains Olivier Testa, speleologist and member of the scientific team. </p>
<p>  Oslisly, Testa and the American researcher <strong> Matthew Shirley </strong> have been multiplying expeditions since 2010 to better understand these crocodiles. When mapping the caves, they found four orange crocodiles on about 40 specimens of this "caveman" species. </p>
<p>  Dozens of "normal" pigmentation crocodiles live in nearby caves connected to the surface, says Testa in caves that are accessible only by vertical wells. </p>
<p>  "We believe that dozens of crocodiles were installed in the caves of <strong> Abanda </strong> about 3 thousand years ago, which corresponds quite well to a period explains Shirley </p>
<p>  The orange crocodiles have probably been trapped in the cave of <strong> </strong>  "after entering the hallways when they were small. "and not being able to get out of it growing up, according to Oslisly. </p>

Shirley maintains, however, that crocodiles may have were installed in their caverns by their own decision and that they can not be trapped there.

Crocodiles in caves have, in fact, a group of unique genes passed down from generation to generation. Scientists have found by comparing blood samples of troglodyte dwelling specimens with those of their dwarf cousins ​​living only on the surface in Gabon.

Although the crocodile is already a protected species in Gabon Oslisly advocates that the caves of Abanda become a "fully protected sanctuary".

"Much remains to be discovered in the caves of Abanda ", says the geoarchaeologist, who hopes to promote "scientific tourism" there.
