Photo by Scott Travers Researchers in the Philippines have discovered a new frog species that was previously thought to be the same species found on another island, but was determined to be unique through genetic testing. The frog, the Mindoro fanged frog ( Limnonectes beloncioi) was previously thought to be the Acanth’s fanged frog (Limn onectes acanthi) that lives on Palawan island. It sported nearly identical physical similarities in looks, almost indistinguishable to the naked eye. However, the mating calls were distinctly different and genetic analysis of the frog by researchers with the University of Kansas’ Biodiversity Institute and Natural History Museum and Department of Ecology & Evolutionary Biology, determined that the frog was indeed a different species from the amphibian on Palawan.
