Correct Option
The correct option isSnow Leopard
Explanation
The Sahara Desert is a hyper-arid, hot environment located in North Africa. The wildlife found in this ecosystem (xerocoles) must possess specific physiological and behavioral adaptations to endure extreme heat and acute water scarcity. In contrast, species adapted to cold, alpine environments are ecologically incompatible with this biome.
Option Analysis
- Fox: Incorrect. Foxes, specifically the Fennec Fox, are iconic inhabitants of the Sahara. They possess large ears to dissipate body heat and are nocturnal to avoid the extreme daytime temperatures.
- Snake: Incorrect. Reptiles such as the Horned Viper and Sand Viper are well-adapted to the desert environment. Their ectothermic nature allows them to thrive in warm climates, and they often bury themselves in sand to regulate temperature.
- Lizard: Incorrect. Lizards, including the Desert Monitor and Spiny-tailed Lizard, are common in the Sahara. They are adapted to retain moisture and withstand high surface temperatures.
- Snow Leopard Snow Leopard: Correct. The Snow Leopard (Panthera uncia) is native to the cold, high-altitude mountain ranges of Central and South Asia (such as the Himalayas and the Pamirs). It possesses thick fur and physiological adaptations for freezing climates, making it impossible for the species to inhabit a hot desert ecosystem like the Sahara.
Key Takeaway: The Snow Leopard is a specialized species of the cold, alpine tundra and mountains of Asia, whereas the Sahara Desert supports fauna adapted to extreme heat and aridity, such as the Fennec Fox and various reptiles.
