Scientific Name: Cremnomys Elvira   

• The Large Rock Rat, also known as the Elvira Rat, is a medium-sized, nocturnal, and burrowing rodent that is endemic to India.
• It primarily inhabits tropical dry deciduous shrubland forests located in rocky terrains.
• This species has an extremely limited distribution, being found only in the Eastern Ghats of Tamil Nadu, at elevations of approximately 600 metres above mean sea level.
• The main threats to its survival include habitat loss, forest conversion for other land uses, and fuelwood collection, which continue to reduce its already restricted habitat.
