Raorchestes Nerostagona
''Raorchestes nerostagona'' is a species of frog in the family Rhacophoridae. It is Endemism, endemic to the Western Ghats, India. It has been called as the Kalpetta yellow bush frog or lichen bush frog for its patchy lichen like patterning that make it cryptic. First described in 2005 based on a specimen obtained in Kalpetta, the species has subsequently been found in many parts of the Western Ghats. This frog has been observed between 900 and 1200 meters above sea level. Taxonomy The species was originally described in the genus ''Philautus'' but has since been moved into the genus ''Raorchestes''. The species name is derived from Greek ''nero'' for water and ''stagona'' for drop and refers to the call of the frog which is emitted from high up in the trees and resembles the sound of a raindrop falling into water. Like all other members of this genus, eggs are thought to develop into little froglets entirely within the egg-shell, although this direct development pattern was n ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ...
