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.
