The Mark's bushfrog (Raorchestes marki) is a critically endangered frog found only in the Nelliampathi Hills within the Western Ghats of Kerala, India.[1] The species is named after Mark Wilkinson of the Natural History Museum, London.
Raorchestes marki are small, slender-bodied frogs. Males measure 21mm23mm in snout–vent length and females 28mm30mm. The dorsum is dark grey and has a brownish concave stripe running from behind the eye.[2]
Like other frogs in Raorchestes, this frog breeds through direct development with no free-swimming tadpole stage.
This frog is classified as critically endangered because its small range is subject to ongoing degradation associated with agriculture, tourism infrastructure, and industrialization.
