Show answer
Answer: (A) Oryx is adapted to live in hot and arid areas whereas Chiru is adapted to live in steppes and semi-desert areas of cold high mountains.
Oryx and Chiru are both antelopes but adapted to completely different environments:
Oryx — adapted to HOT, ARID deserts (found in Africa and Arabia; the Arabian Oryx can survive extreme heat and water scarcity).
Chiru (Tibetan Antelope) — adapted to COLD, HIGH-ALTITUDE steppes and semi-deserts of the Tibetan Plateau (found at 3,700-5,500m elevation).
Option (b) is wrong — Chiru is poached for its ultra-fine underwool (shahtoosh), not musk. Oryx has horns, not antlers.
Option (c) is wrong — Oryx is not native to western India, and Chiru is found in Ladakh, not northeast India.
Answer: (a).
Chiru (Tibetan antelope) became globally famous because its ultra-fine underwool is used to make shahtoosh shawls, leading to severe poaching and making it an endangered species.
The question tests whether students can distinguish between hot desert adaptation (Oryx) versus cold high-altitude adaptation (Chiru) - two completely different evolutionary responses to harsh environments.
Oryx Antelope
Environment Oryx
Oryx Antelope: Hot Desert Specialist
Oryx is adapted to hot, arid deserts with extreme heat tolerance
Found in Africa and Arabia, not native to India
Has straight horns (not antlers) and exceptional water conservation abilities
Desert Adaptations
Oryx represents one of nature's most successful desert mammals, thriving in environments where temperatures exceed 45°C and water is scarce for months.
• Water independence: Can survive without drinking water by extracting moisture from vegetation
• Heat regulation: Light-colored coat reflects sunlight; specialized blood vessel system cools the brain
• Behavioral adaptations: Seeks shade during peak heat, active during cooler hours
Key Oryx Species
Species | Location | Conservation Status | Key Feature |
|---|---|---|---|
Arabian Oryx | Arabian Peninsula | Vulnerable (recovered from extinction) | First species brought back from extinction in wild |
Scimitar Oryx | North Africa (Sahara) | Extinct in Wild | Curved horns, reintroduction programs active |
Gemsbok | Southern Africa (Kalahari) | Least Concern | Longest straight horns, most heat-tolerant |
Arabian Oryx Habitat
Source: Britannica — Oryx | African Antelope, Horned Mammal & Endangered Species ... · www.britannica.com
Trap: Oryx has horns, not antlers (antlers are found in deer family, shed annually)
Trap: Oryx is not native to western India — it's from Africa and Arabia
Geographic confusion: Arabian Oryx ≠ Indian species; no wild Oryx populations in India
Chiru (Tibetan Antelope)
Environment Chiru
Chiru: High-Altitude Cold Desert Specialist
Chiru lives in cold, high-altitude steppes and semi-deserts of Tibetan Plateau
Poached for shahtoosh wool (underwool), not musk
Found at 3,700-5,500m elevation in Ladakh, Tibet, and Qinghai
Males have lyre-shaped horns, females are hornless
High-Altitude Adaptations
Chiru (Pantholops hodgsonii) is perfectly adapted to the harsh conditions of the Tibetan Plateau, where winter temperatures drop to -40°C and oxygen levels are half of sea level.
• Ultra-fine underwool: Provides insulation against extreme cold
• Large lungs and heart: Enhanced oxygen processing at high altitude
• Seasonal migration: Travels hundreds of kilometers between summer and winter ranges
Chiru Distribution & Status
Region | Population | Elevation Range | Key Threats |
|---|---|---|---|
Ladakh (India) | Small population | 4,000-5,500m | Poaching, habitat loss |
Tibet (China) | Largest population | 3,700-5,300m | Illegal hunting for wool |
Qinghai (China) | Breeding grounds | 4,500-5,500m | Infrastructure development |
Shahtoosh Crisis
Shahtoosh shawls are made from Chiru's ultra-fine underwool and can cost $5,000-20,000. One shawl requires wool from 3-5 dead Chiru, as the wool cannot be collected from living animals. This has driven massive poaching across the Tibetan Plateau.
Chiru Habitat
Source: Great Tibet Tour — Tibetan Antelope: Facts, Behavior, Migration and Protection · www.greattibettour.com
Trap: Chiru is poached for shahtoosh wool, not musk (musk comes from musk deer)
Geographic trap: Chiru is found in Ladakh, not northeast India
Terminology: 'Tibetan Antelope' = Chiru = Pantholops hodgsonii (same animal, different names)
Oryx vs Chiru Key Differences
Environment antelopes difference
Oryx vs Chiru: Opposite Climate Adaptations
Key difference: Oryx = hot deserts, Chiru = cold high mountains
Both are antelopes but evolved for completely opposite climates
Direct Comparison
Aspect | Oryx | Chiru |
|---|---|---|
Climate | Hot, arid deserts | Cold, high-altitude steppes |
Temperature Range | 45°C+ (extreme heat) | -40°C (extreme cold) |
Elevation | Sea level to 1,500m | 3,700-5,500m |
Geographic Region | Africa, Arabian Peninsula | Tibetan Plateau, Ladakh |
India Presence | Not native to India | Found in Ladakh |
Poaching Reason | Minimal (horns occasionally) | Shahtoosh wool |
Horn/Antler Type | Straight horns (both sexes) | Lyre-shaped horns (males only) |
Water Dependency | Can survive without drinking | Depends on seasonal water sources |
Question Context
This 2012 UPSC question tested understanding of climate-based adaptations in antelopes. The correct answer (Option A) hinged on recognizing that Oryx and Chiru represent opposite extremes of mammalian climate adaptation — one for scorching heat, the other for freezing cold.
Statement trap: Option B falsely claims Chiru is poached for musk (wrong animal - that's musk deer)
Geographic trap: Option C places Oryx in 'western India' and Chiru in 'northeast India' (both wrong)
Terminology confusion: Horns (permanent, both sexes) vs antlers (shed annually, deer family)
Antelope Species in India
Environment
Native Antelope Species of India
India has 4 native antelope species: Blackbuck, Chinkara, Four-horned Antelope, Chiru
Oryx is not native to India despite being tested in UPSC questions
Most Indian antelopes prefer grasslands and scrublands, except Chiru (high-altitude)
Indian Antelope Species
Species | Habitat | Distribution in India | Conservation Status | Key Protected Areas |
|---|---|---|---|---|
Blackbuck | Grasslands, scrublands | Rajasthan, Gujarat, Punjab | Near Threatened | Velavadar NP, Point Calimere |
Chinkara (Indian Gazelle) | Desert, semi-arid areas | Rajasthan, Gujarat, Haryana | Least Concern | Desert NP, Tal Chhapar |
Four-horned Antelope (Chousingha) | Dense forests, hills | Central & Southern India | Vulnerable | Panna NP, Kanha NP |
Chiru (Tibetan Antelope) | High-altitude steppes | Ladakh only | Endangered | Changthang Wildlife Sanctuary |
Habitat-wise Classification
# Indian Antelopes
## Grassland Species
- **Blackbuck** (open grasslands)
- **Chinkara** (arid grasslands)
## Forest Species
- **Four-horned Antelope** (dense forests)
- Only antelope with 4 horns
## High-Altitude Species
- **Chiru** (Tibetan Plateau)
- Cold desert specialistCommon mistake: Including Oryx as an Indian species (it's African/Arabian)
Four-horned confusion: Chousingha is the only antelope with 4 horns (unique globally)
Range confusion: Chiru in Ladakh ≠ Chinkara in Rajasthan (different species, similar names)
