Rana holtzi, also known as the Taurus frog,[2] is a frog species of the Ranidae family endemic to Turkey, varying in size from 6.0 to 7.5cm.[3] It is the only extant frog species that doesn't croak.[4] Although it was only thought to be present in Karagöl and Çiniligöl, research conducted in 2007 revealed Eğrigöl as another habitat where the species is present.[5]
