  • Adaptability to different rocky habitats influences the survival and distribution of the Elvira rat and the Cutch rock rat.
  • The Elvira rat is a Critically Endangered rodent found only in the Shervaroy Hills of Salem district, Tamil Nadu, and is closely associated with the rare Shonkinite rock formation.
  • The Cutch rock rat has a wider distribution because it can adapt to various rocky habitats, including granite, quartzite, basalt, and Deccan Trap formations.
  • The Elvira rat has a very restricted habitat range, while the Cutch rock rat is found in parts of Tamil Nadu and Rajasthan, making it relatively more resilient.
  • The Cutch rock rat plays an important ecological role as a prey species for animals such as the Bengal fox and several raptor species.
