Researchers have discovered a new miniature frog species in the Pilbara region of Western Australia.

The researchers from the Australian National University in Canberra, the Western Australia Museum and the University of Western Australia in Perth discovered the new toadlet after they conducted genetic analysis on the various frog species found in the dry region.

The new species, called the Pilbara toadlet (Uperoleia saxatilis), measures just two centimeters long and is found in the rocky gorges and creeks of the arid region.

Lead researcher and PhD student from ANU, Renee Catullo said the new toadlet is unique for its species.

"It has big glands and it has brown spots all over it, it also has a different call from all the other species," she said.

"It actually lives in rocky landscapes instead of sandy soils, so it's a burrowing frog that's adapted to live in a different type of landscape."

Researchers used genetic techniques to identify the new species from its better known northwest cousins.

"Genetic techniques are increasingly being used to identify new species across Australia that use calls, pheromones, or behavior to tell each other apart. In these cases genetic techniques can tell us which groups are interbreeding, even when it's hard to visually differentiate them."

"Little is known about this small, brown creature, but it has been found following cyclonic rains and occurs in rocky gorges and creeks of the region," Catullo added.

The new discovery has proven that the deserts of Australia are teeming with life. The barren landscape could still hold new species that scientists haven't found yet.

"This new breakthrough emphasizes the need for further research into understanding the biodiversity of Australian deserts."
