It resides in Asia. Its origin is in India and South-East Asia. It is a terrestrial tortoise which can be found in all continents around the world. There are 39 different types of it. Adult males typically reach up to 26 cm and adult females typically up to 32 cm in carapace length (Moll 1989). Observations made from nearly 400 star tortoises from various parts of the country indicate that the female is larger and heavier than the male. In Sri Lanka so far the record is of a female measuring 380 mm straight carapace length and weighed 6.6 kg kept in a tourist hotel in Hambantota (South East Sri lanka) (Jayawardena 1997). In India, Vyas (2011) reported of the largest recorded star tortoise from Sayaji Baug Zoo, India with a body weight (8.96 kg) that had a straight carapace length of 41.0 cm. Matz et al. (1971) reported a star tortoise from India which weighed 7.0 kg and 38.0 cm carapace length. Frazier (1987) reported of another specimen from Jasdan, Rajkot District, Gujarat with 42.9 cm curved carapace length. All these Geochelone elegans of exceptionally large size were females. Comparing local as well as world records of exceptionally large star tortoises, it is certain that the star tortoise from Lunugamwehera National Park, Sri Lanka is the currently known largest and heaviest star tortoise in the world (Curved carapace length 57.5 cm and weighed 14 kg) (de Silva et al. 2017). Females attain sexual maturity at around 6–7 years of age (possibly earlier) (Das 1991, R. Vyas pers. comm. 2005). However, in captivity this may be attained by the age of three years (B.C. Choudhury pers. comm. 2005). Nesting seasons coincide with the monsoons that vary depending on the geographic location (e.g., May to June in western India, March to June and October to January in southeastern India) (Das 2002). Annually, females typically produce two clutches (exceptionally up to four clutches) comprising 2–10 eggs (exceptionally up to 24 eggs; Andrews, B.C. Choudhury, R. Vyas, pers. comm. 2005). Generation time has been estimated to be around 10 years (B.C. Choudhury, pers. comm. 2005). A detailed overview of natural history is presented by Das (2002), de Silva (2003), Deraniyagala (1939) and Fyfe (2007). Star tortoises inhabit a variety of dry vegetation types, including scrublands, grasslands, desert edges and agricultural landscapes of fields, hedgerows and plantations (de Silva 2003, Fyfe 2007). It is a highly generalized habitat preference species (Moll 1989, de Silva, 2017). Most localities occur under 200 m altitude, but records from 450 m and even as high as 900 m have been reported (Andrews pers. comm. 2005). In Sri Lanka, this species occurs throughout the dry habitats mainly up to 270 m altitude (Rathnayake pers. comm. 2005, de Silva 2003). Indian Star Tortoises feed mainly on a variety of grasses, herbaceous, succulent vegetation and fruits supplemented with some animal matter (Das 1991, de Silva 2003). Although the star tortoise is largely herbivorous they have been observed feeding on dry dog faecal matter. They come to road sides searching for faecal matter of dogs in fact some villagers around the Mihintale Sanctuary informed us that they have seen the star tortoise feeding on dry dog excreta on the road (Jayawkrama et al. 2010). Choudhury and Rao (2005) recorded several species of indigenous plant that were preferred by Indian Star Tortoises in a soft release site in Andhra Pradesh.
