University of Newcastle, Australia found out two new, very loud frog species from eastern Australia named the Slender Bleating Tree Frog or Litoria balatus and Screaming Tree Frog or Litoria quiritatus. The Slender Bleating Tree Frog can be seen in Queensland and the Screaming Tree Frog can be seen in Victoria.
The scientists at first thought the two frog species are one, the Bleating Tree Frog or Litoria dentata. Scientists also say that the Bleating Tree Frog is well known to the people of east coast of Australia for its loud and piercing call.
The scientists took help of the FrogID project to analyse the calls of the frog and to differentiate the calls. From there scientists found out there are species based on genetic work.
All these three species have its unique appearance. The Slender Bleating Tree Frog is slender, and has a white line extending down its side.
The Screaming Tree Frog is not at all slender and male Screaming Tree Frog has a bright yellow vocal sac. In breeding season, the male body turn into lemon yellow in colour.
The Robust Bleating Tree Frog looks similar to a Screaming Tree Frog. But male Robust Bleating Tree Frog has a brownish vocal sac.
Scientists say, these three new-found species are closely related to each other and they are widespread throughout Australia.
