In the rainforests of Malaysia and across the broader Southeast Asian archipelago, a solitary, scale-armoured animal moves silently through the night. The Sunda pangolin (Manis javanica) — also called the Malayan pangolin or Javan pangolin — is arguably the most trafficked wild mammal on Earth. Its scales, sought for use in traditional medicine, have made it the target of industrial-scale poaching networks that have devastated populations across its entire range over the past four decades.
The Sunda pangolin is one of four pangolin species native to Asia, and one of eight pangolin species worldwide. It belongs to the family Manidae and the genus Manis, the same genus that includes the Chinese, Indian, and Philippine pangolins. The species was first formally described by the Dutch naturalist Coenraad Jacob Temminck in 1824, based on specimens from Java.
Common names vary by country and language. In Malaysia it is known as tenggiling; in Indonesia as trenggiling or peusing; in Vietnam as tê tê Java. English speakers use Sunda pangolin, Malayan pangolin, or Javan pangolin interchangeably, though Sunda pangolin is increasingly the preferred scientific and conservation usage.
The Sunda pangolin is a medium-sized pangolin, considerably smaller than the giant pangolin of Africa. Adults weigh between 4 and 10 kilograms and measure 40 to 65 centimetres in body length, with the tail adding a roughly equivalent length. Males are slightly larger than females on average.
The dorsal surface is covered in overlapping brown-grey or olive-brown scales arranged in seventeen to nineteen rows. These scales are narrower and more pointed than those of many African species, giving the animal a slightly more streamlined appearance. The face, throat, inner surfaces of the limbs, and belly are covered in sparse yellowish-white hair.
One of the Sunda pangolin's most distinctive physical features is its climbing adaptation. Unlike the largely ground-dwelling Temminck's ground pangolin of Africa, the Sunda pangolin is an accomplished tree climber. It has a semi-prehensile tail capable of gripping branches and a more flexible body plan that allows it to navigate complex arboreal environments with surprising agility.

The Sunda pangolin has one of the widest distributions of any Asian pangolin species. Its range encompasses:
Within this range, the Sunda pangolin is habitat-generalist by pangolin standards. It has been recorded in primary rainforest, secondary growth, logged forest, rubber and oil palm plantation edges, and even in urban green spaces in Singapore. This flexibility is one of the reasons it was historically abundant; it did not need pristine habitat to survive. However, this same flexibility made it accessible to hunters across a wide range of land-use types.
The Sunda pangolin is strictly nocturnal and highly solitary outside of mating interactions and mother-offspring pairs. During the day it rests in tree hollows, dense brush, or in burrows that it may excavate itself or inherit from other animals. In Borneo and Sumatra, individuals show a stronger tendency for arboreal resting sites than their counterparts on the Asian mainland.
Foraging begins after dark. The Sunda pangolin follows a relatively consistent nightly circuit through its home range, targeting ant and termite nests in both the soil and in trees. It locates colonies primarily through smell, sniffing along bark, soil surfaces, and leaf litter until chemical cues betray a nest location. Its long, extensible tongue — coated in sticky saliva — then extracts insects from deep within tunnels and chambers.
Like all pangolins, the Sunda pangolin lacks teeth entirely. Insects are ground up in a muscular, gizzard-like stomach that often contains small stones ingested deliberately to assist with the process. This specialised digestive anatomy means that pangolins cannot be fed on anything other than live insects in captivity — a significant challenge for rescue and rehabilitation programmes.
The Sunda pangolin typically produces a single offspring per year, though twins are occasionally recorded. Births appear to peak in the dry season in parts of the range, though data from across the full distribution are limited. Newborns weigh around 100 grams and are born with soft, pale scales that harden within a few days of birth.
The mother carries her offspring on her tail and lower back for the first three months of life, curling protectively around it when threatened. Juveniles begin to follow their mother on foraging trips from around three months of age and become independent at around five to six months. Sexual maturity is reached at about two years.
No discussion of the Sunda pangolin can avoid the catastrophic impact of wildlife trafficking. Between 2000 and 2019, seizure data compiled by TRAFFIC and other monitoring organisations documented tens of thousands of Sunda pangolins — and hundreds of tonnes of scales — intercepted by law enforcement across Southeast and East Asia. These figures represent only a fraction of actual trade volumes; enforcement agencies estimate that fewer than one in ten shipments is detected.
The primary demand driver is traditional Chinese medicine, where pangolin scales are used — without any verified clinical efficacy — in treatments for conditions ranging from skin disorders to poor lactation. Pangolin meat is also consumed as a luxury food item in Vietnam and China. A single Sunda pangolin carcass sold at black-market prices in 2019 was reportedly worth more than USD 1,000; the scales alone from a kilogram of product could fetch several hundred dollars on end markets.
The scale of the trade means that local populations in heavily harvested areas have been functionally eliminated. Vietnam, once home to abundant Sunda pangolin populations, has seen near-total depletion in many provinces. Malaysia has fared somewhat better in areas with active law enforcement and intact protected areas, but remains a source country for trafficking networks supplying the Chinese market.
International trade in Sunda pangolins has been prohibited under CITES Appendix I since 2016, upgrading the species from Appendix II at the CoP17 meeting in Johannesburg. Domestic protection varies: Malaysia's Wildlife Conservation Act provides legal protection, though penalties have historically been insufficient to deter organised trafficking networks. Vietnam, Indonesia, and Thailand all have legal protections in place, with enforcement effectiveness varying widely.
Rescue and rehabilitation centres in Malaysia, particularly on the peninsular and in Sabah, have developed significant expertise in caring for confiscated pangolins, though the animals' dietary requirements and stress sensitivity make rehabilitation and release extremely challenging. Singapore's National Parks Board has run one of the most successful urban pangolin monitoring programmes in the region, using camera traps and GPS tracking to document population trends in green corridors and nature reserves.
Community engagement programmes in Sabah and Sarawak are working with indigenous communities to reduce hunting pressure, linking pangolin protection to broader forest rights and livelihood frameworks. The argument that living pangolins generate more value through tourism and ecological services than dead ones sold to traffickers is gaining traction in some communities, though economic pressure remains the dominant reality for many rural households.
The Sunda pangolin is an ecological engineer of the Southeast Asian rainforest. By consuming enormous quantities of ants and termites, it regulates insect populations that would otherwise cause significant damage to forest trees and agricultural crops. Its burrowing activity aerates soil and redistributes nutrients. In its absence, these ecological functions go unfulfilled.
Its story is also a stark illustration of how traditional medicine demand, combined with weak enforcement, can drive a widespread, adaptable species to the edge of extinction within decades. The Sunda pangolin was not rare when large-scale commercial harvesting began. It was common — and that commonness masked how vulnerable it was to sustained, industrialised hunting pressure. Reversing its decline requires not only stronger law enforcement but a fundamental shift in demand at the consumer end of the supply chain.
Yes. The Sunda pangolin (Manis javanica) is listed as Critically Endangered on the IUCN Red List. It is one of the most heavily trafficked wild mammals on Earth, with populations declining sharply across Southeast Asia due to poaching for scales and meat.
The Sunda pangolin is found across much of Southeast Asia, including Malaysia, Indonesia (Borneo, Sumatra, Java), Thailand, Vietnam, Laos, Cambodia, Myanmar, and Singapore. It lives in tropical and subtropical forests, including primary rainforest, secondary growth, and forest-edge habitats.
Reliable population estimates for the Sunda pangolin are not available due to the species' secretive nocturnal behaviour. However, population declines of more than 80 percent over three generations are suspected, qualifying it for Critically Endangered status under IUCN criteria.
