New frog species discovered at sky islands in Brazil

New frog species discovered at sky islands in Brazil

The isolated patches of land are heaven for endangered species to take rescue. These areas, often inaccessible to human being have become ecological hotspot. The scientists recently discovered endangered miniature frogs on remote mountaintops in Brazil.  Seven new species have been found which are smaller than bumblebees. 

 The biggest frog has length of 13 millimeter. The researchers are claiming that despite being smallest vertebrate on the planet, these tiny creatures have managed to develop fingers and toes by maintaining small size.  The small shapes prepare them to come out from the egg. Though smaller in size since birth, these creatures are fully evolved adults since birth.  This allows them to skip tadpole stage and can live away from water. The skin of these tiny frogs is equipped to absorb moisture from the soil so they don’t need to be in water to stay moisturized.   The five-year long expedition studied the mountainous region located at Atlantic coast in the southern Brazil. 

 The team was headed by Professor Marcio Pie from the Universidade Federal do Paraná, which published their findings in PeerJ, a research journal.  The researcher informed about difficulties faced in accessing the remote location but the curiosity over the new species and research drove the team. Brachycephalus Genus of frogs, known for its tiny size also contains these five new species now.  The rainforest in located on a sky island, a land form surrounded by all high altitude forests. The frogs have been struck in the region since million years and their lifestyle has been altered by isolation.
