Correct option is D
Saara hardwickii, commonly known as the spiny-tailed lizard or the Hardwicke’s spiny-tailed lizard, is endemic to the Thar Desert in India. This species is primarily found in arid, sandy habitats with sparse vegetation, characteristic of the desert ecosystem. It is adapted to the harsh desert environment and is commonly seen in open, sun-exposed areas during the daytime, which is typical of its diurnal nature.
Information Booster:
- The Thar Desert, located in the northwestern part of India, is a hot, arid region with extreme temperatures and limited water resources. The spiny-tailed lizard is perfectly suited to such environments due to its ability to burrow and adapt to high temperatures.
- The species plays a role in controlling insect populations and is an important part of the desert ecosystem. It is often found basking on rocks and in open spaces where it can absorb heat from the sun.
Additional Information:
- Rainforests of Eastern Himalayas (Option 1): This is not the correct habitat for Saara hardwickii, as it is typically found in dry, arid regions, not tropical rainforests.
- Dry deciduous forests of central India (Option 2): While this habitat may be suitable for other lizards, Saara hardwickii is specifically associated with the Thar Desert rather than central India’s dry forests.
- Moist deciduous forests of Western Ghats (Option 3): This is also incorrect. The Western Ghats are characterized by lush, moist vegetation, which is not the typical habitat of the spiny-tailed lizard, which prefers arid environments.
