Understanding The Differences Between Antelope and Deer
Context: Recently, Blackbuck and Chinkara are at the centre of the news cycle given the tragic murder of Nationalist Congress Party leader Baba Siddique in Mumbai.
Key Differences between Antelope and Deer
- Taxonomy
- Both deer and antelope belong to the kingdom Animalia and the order Artiodactyla (even-toed ungulates).
- Deer belong to the family Cervidae, while antelope are part of the family Bovidae (which also includes cattle, buffalo, goats, etc.)
- Physical Characteristics
- Deer have antlers: Branching, keratinous growths present only in males and shed annually.
- Antelope have horns: Permanent, unbranched, strong, and composed of a chitinous shell with a bony core, present in both males and females.
- Body Structure
- Antelopes: Generally have longer legs and more slender bodies, adapted for speed and agility in open habitats.
- Deer: Tend to have stockier builds with shorter legs compared to many antelope species.
- Behaviour
Antelopes: Antelopes have adapted a wide range of habitats, typically woodland, forest, savannah, grassland plain, desert (hot and cold), swamp,marshes, etc. and several species are living in the mountain and rocky outcrops.
- They often live in large herds and rely on speed and agility to evade predators.
- Deer: May form smaller groups and are often found in forested areas.
- They rely more on camouflage and stealth, along with speed, to avoid predators.
Geographical Distribution of Antelope
- Distribution: There are 91 species of antelopes worldwide, primarily in Africa and Asia with Africa being the ‘antelope haven.’
- Antelopes in India: India has six antelope species: Tibetan Antelope, Tibetan Gazelle, Nilgai, Blackbuck, Chinkara, and Chausingha.
- Threats to Antelope Populations: Hunting, habitat destruction, competition with livestock and wars and conflict.
Global Distribution of Deer
- There are 43 species of deer found across various regions, from the Americas to Eurasia.
- Moose: The largest deer species, found in North America (called Elk in Eurasia).
- Pudu: The smallest deer species, native to South America.
- Deer in India: India is home to 12 species of deer.
- Indian Mouse Deer (smallest)
- Sambar (largest)

Reclassification of King Cobra
Context: Recently, Scientists have recategorised King Cobra (s) into four distinct species.
About King Cobra
- It is the world’s longest venomous snake and among the heaviest.
- King cobra bites, while rare, affect the respiratory centres in the brain, causing respiratory arrest, cardiac failure and can have lethal neurotoxic effects.
- Distinctive Features:
- Diet: Primarily snake-eaters, consuming both venomous and nonvenomous species.
- Nest-Building: The king cobra is the only snake that builds a nest to lay eggs , which they fiercely guard until the hatchlings emerge.
- Hiss: The hiss of the king cobra is a much lower pitch than many other snakes and many people compare its call to a “growl” rather than a hiss.
- Facultative Parthenogenesis in King Cobras: King cobras have demonstrated the ability to undergo facultative parthenogenesis, a form of asexual reproduction where females can produce offspring without fertilisation by a male.
- Habitat: Adaptable to various habitats, including rainforests, bamboo thickets, mangrove swamps, high-altitude grasslands, and rivers etc.
- Threats: Deforestation, International pet trade, wildlife smuggling, Persecution by humans, Exploitation for skin, food, and medicinal purposes etc.
- Protection Status
- IUCN Red List: Vulnerable
- CITES: Appendix II
- Wildlife (Protection) Act, 1972: Schedule II
- Re Categorisation into Four Distinct Species: The king cobra is now classified into four species:
- Mainland Asia Northern king cobra (Ophiophagus hannah) : Extends from eastern Pakistan through northern India to parts of Southeast Asia
- Sunda king cobra (Ophiophagus bungarus): Found in areas south of the Kra Isthmus, including Malaysia and some southern Philippines islands.
- Western Ghats king cobra (Ophiophagus kaalinga): Endemic to the Western Ghats in India, inhabiting mid-elevation rainforests and foothills.
- Luzon king cobra (Ophiophagus salvatana): Exclusive to Luzon Island in the northern Philippines, with potential undiscovered populations on other islands.
- Their reclassification has significant implications for king cobra conservation and can also aid in reducing fatalities from their bites.
Jiangmen Underground Neutrino Observatory (JUNO)
Context: After years of construction, the $300 million Jiangmen Underground Neutrino Observatory (JUNO) in China’s southern Guangdong province will soon start gathering data on neutrinos, a product of nuclear reactions, to help solve one of the biggest mysteries in particle physics.
About Jiangmen Underground Neutrino Observatory (JUNO)
- Location: Southern Guangdong Province, China.
- Cost: $300 million.
- Purpose: To study neutrinos, subatomic particles from nuclear reactions, for understanding particle physics and the universe.
- Construction: A giant sphere with light-detecting tubes, housed in a 12-storey pool of water, 700 metres underground.
- Operational: Expected to start in 2025.
- Scientific Objectives:
-
- Neutrino Mass Hierarchy: JUNO aims to determine which neutrino types are lightest and heaviest—a crucial question in particle physics.
- Study of Solar Processes: Real-time observation of neutrinos from the Sun for insights into solar energy generation.
- Earth Studies: Investigate neutrinos from radioactive decay in Earth’s mantle to understand tectonic plate movement.
- Nuclear Power Plants: JUNO will analyse neutrinos from two nearby nuclear plants for up to six years.
About Neutrinos
- Type of subatomic particle.
- Mass and Charge: Don’t have an electric charge, have a small mass, and are left-handed (a physics term meaning the direction of its spin is opposite to the direction of its motion).
- Abundance of Neutrinos: Second-most abundant particles after photons (particles of light) and the most abundant among particles that make up matter.
- Types/Flavours: Three types or “flavours” – electron neutrino, tau neutrino and muon neutrino.
- Neutrino Oscillation: They can change from one flavour to another as they travel. This is an unusual quantum phenomenon.
- Example: Neutrinos from the Sun are initially electron-neutrinos, but on Earth, many of them are detected as muon-neutrinos.
- Observation: Neutrinos’ weak charge and almost nonexistent mass have made them notoriously difficult for scientists to observe.
- They can only be “seen” when they interact with other particles
India’s Neutrino Project
- India-based Neutrino Observatory (INO): Planned for Tamil Nadu, India.
- Location: The INO collaboration has decided on a site in the Bodi West Hills (BWH) region in the Theni district of Tamil Nadu.
- Funding and Support: Funded by the Department of Atomic Energy.
- Current Status: Faces an uncertain future due to procedural issues and lack of political support.

Battle of Walong
Context: To mark the 62nd anniversary of the iconic battle of Walong during the 1962 war with China, the Army is planning a month-long series of commemorative events beginning on October 17 till November 14.
About Battle of Walong
- During the 1962 Indo-China war, Indian troops halted the advancing Chinese People’s Liberation Army (PLA) for 27 days in the Walong sector, Arunachal Pradesh.
- The 11 Infantry Brigade defended against the PLA with 800 soldiers, halting 4,000 PLA troops and forcing China to deploy an additional division of 15,000 soldiers.
- Geographical Challenges:
- The battles were fought at altitudes ranging from 3,000 to 14,000 feet in rugged terrain.
- The sector was completely dependent on air maintenance and lacked a road link, adding logistical challenges for Indian forces.
- The battle was a testament to the bravery of the Indian Army despite being outnumbered and under-resourced. The Time Magazine (1963) praised the Indian soldiers for their “guts.”
