The Indian Pangolin: South Asia’s Armoured Guardian Under Threat

Introduction

The Indian pangolin (Manis crassicaudata), also known as the thick-tailed pangolin, is the largest of the four Asian pangolin species and one of the most enigmatic mammals on the Indian subcontinent. Clad in overlapping keratinous scales that form a near-impenetrable suit of armour, this solitary, nocturnal creature has inhabited the forests and scrublands of South Asia for millions of years. Yet despite its remarkable adaptations, the Indian pangolin now faces an uncertain future. Classified as Endangered by the International Union for Conservation of Nature (IUCN), it is under mounting pressure from poaching, illegal trade, and habitat destruction.

Taxonomy and Classification

The Indian pangolin was first described by the French naturalist Étienne Geoffroy Saint-Hilaire in 1803. It belongs to the order Pholidota, a lineage that diverged from other placental mammals tens of millions of years ago. The family Manidae contains all eight extant pangolin species, split between Asia and Africa. Within this family, Manis crassicaudata sits alongside three other Asian species: the Sunda pangolin (M. javanica), the Chinese pangolin (M. pentadactyla), and the Philippine pangolin (M. culionensis). The species name crassicaudata derives from Latin — crassus (thick) and caudata (tailed) — referencing its robust tail.

Physical Description and Adaptations

The Indian pangolin is a sturdily built animal, with adults typically measuring 60 to 75 centimetres in head-and-body length and weighing between 10 and 16 kilograms. Its tail, which can reach up to 45 centimetres, is notably thicker and more muscular than that of other Asian pangolins — an adaptation linked to its predominantly terrestrial lifestyle. The body is covered in large, overlapping scales composed of keratin, the same protein found in human fingernails. These scales number roughly 160 to 200 across the body and serve as formidable protection: when threatened, the pangolin rolls into a tight ball, presenting an armoured exterior that deters most predators.

Perhaps the Indian pangolin’s most impressive adaptation is its forelimbs. Equipped with large, curved claws — the third claw being the longest and most powerful — these limbs are built for excavation. The species is a burrowing specialist, capable of digging deep tunnels into compacted earth and breaking apart rock-hard termite mounds with ease. Its elongated, sticky tongue, which can extend up to 25 centimetres beyond its mouth, is coated in viscous saliva produced by enlarged salivary glands, allowing it to sweep up hundreds of insects per feeding session. The Indian pangolin lacks teeth entirely, instead relying on keratinised spines within its muscular stomach to grind its food.

Range and Habitat

The Indian pangolin is distributed across the Indian subcontinent, with confirmed populations in India, Sri Lanka, Pakistan, Nepal, and Bangladesh. Historical records also suggest its presence in parts of western Myanmar, though the current status there remains unclear. Within this range, the species occupies a variety of habitats, from tropical and subtropical moist forests and dry deciduous woodlands to thorn scrublands, grasslands, and degraded landscapes near agricultural areas.

What distinguishes the Indian pangolin from its arboreal relatives is its strongly terrestrial habit. While other Asian pangolins spend considerable time in trees, M. crassicaudata favours the ground, where it excavates extensive burrow systems. These burrows serve multiple functions: daytime resting shelters, refuges from temperature extremes, nursery dens for mothers and young, and escape routes from predators. The species has been recorded from sea level to elevations of approximately 1,500 metres, demonstrating considerable ecological flexibility.

Diet and Behaviour

The Indian pangolin is strictly nocturnal, emerging from its burrow after dark to forage. Its diet consists almost exclusively of ants and termites, making it a specialised insectivore. Using its acute sense of smell — its eyesight is relatively poor — the pangolin locates insect colonies, then deploys its powerful fore-claws to tear open mounds, rotting logs, and soil. The long, adhesive tongue does the rest, probing deep into tunnels and chambers to extract prey. A single pangolin may consume tens of thousands of insects in one night, providing a significant ecological service by regulating insect populations.

Outside of mating, Indian pangolins are solitary animals. They are generally slow-moving and non-aggressive, relying on their armour and burrowing ability rather than speed or confrontation for defence. When encountered by a predator, the pangolin curls into a ball, tucking its head beneath its tail. The edges of its scales can also be used defensively, as the animal contracts its muscles to create a cutting action that can injure an attacker’s paws or mouth. Females typically give birth to a single offspring, which rides on the mother’s tail during foraging trips for the first several months of life.

Conservation Status and Threats

The IUCN Red List classifies the Indian pangolin as Endangered, a status reflecting steep population declines driven primarily by human activity. Unlike the Sunda and Chinese pangolins, which are listed as Critically Endangered, the Indian pangolin’s somewhat broader range has thus far prevented it from reaching the most dire category — but the trajectory is alarming.

The threats facing the Indian pangolin are multifaceted:

• Illegal hunting and trade: Pangolin scales are in high demand for use in traditional medicine across parts of Asia, despite the absence of scientific evidence supporting their medicinal efficacy. Pangolin meat is also consumed as a luxury item. The Indian pangolin is frequently poached to supply both domestic and international markets.
• Habitat loss: Expanding agriculture, urban development, mining, and infrastructure projects have reduced and fragmented the species’ natural habitat across its range.
• Electrocution: Electric fences erected to protect crops from wildlife have become an increasingly documented cause of pangolin mortality in India and Sri Lanka, as the animals inadvertently contact live wires while foraging or moving between habitats.
• Low reproductive rate: With females typically producing only one offspring per year, populations are slow to recover from losses.

Conservation Efforts

The Indian pangolin benefits from robust legal protections on paper. In India, it is listed under Schedule I of the Wildlife Protection Act of 1972, which grants it the highest level of legal protection and makes hunting, trading, or possessing the species a criminal offence punishable by imprisonment. Internationally, the 2017 uplisting of all eight pangolin species to CITES Appendix I imposed a zero-quota ban on commercial international trade in pangolins and their derivatives.

On-the-ground conservation efforts are gaining momentum. Community-based programmes in states such as Odisha, Tamil Nadu, and Maharashtra work with local and Indigenous communities to reduce hunting pressure, promote awareness, and develop alternative livelihoods. Researchers are expanding the use of camera traps and burrow surveys to establish baseline population data — a critical gap, as the secretive nature of pangolins makes population assessment exceptionally difficult. Rescue and rehabilitation centres across India increasingly receive pangolins confiscated from traffickers, though the long-term survival rates of released individuals remain an area of active study.

“Pangolins are the world’s most trafficked mammals, yet they remain among the least studied. Every seizure represents dozens more animals that were never intercepted.”

The Global Trade Connection: Asia and Africa

The plight of the Indian pangolin cannot be understood in isolation. As enforcement has intensified in parts of Asia and wild populations have declined, trafficking networks have increasingly turned to African pangolin species to supply Asian markets. Seizures of African pangolin scales in ports across Southeast and East Asia have surged in recent years, revealing a globalised supply chain that links poaching in West and Central Africa to demand-driven markets thousands of kilometres away.

This intercontinental dynamic has direct implications for Indian pangolin conservation. Trafficking networks that operate across South Asia often serve as transit routes or feeder systems for the broader international trade. Disrupting these networks requires coordinated cross-border law enforcement, intelligence sharing, and demand-reduction campaigns targeting the end consumers. Organisations working on pangolin conservation increasingly advocate for a holistic approach that addresses all eight species simultaneously, recognising that the trade in one species fuels the exploitation of others.

Looking Forward

The Indian pangolin stands at a crossroads. Its legal protections are among the strongest of any wildlife species, yet enforcement remains inconsistent across its range. The illegal trade continues to extract animals faster than populations can replenish. However, there are reasons for cautious optimism: growing public awareness, expanding community conservation initiatives, and improving cross-border enforcement cooperation all point toward a more coordinated defence of this remarkable species. The Indian pangolin has survived for millions of years. With sustained commitment, it can endure for millions more.
