Pangolins: the protective scales that became a trafficking target

Pangolins are the only mammals covered in overlapping keratin scales. The scales protect the animal from some predators, while a threatened pangolin may curl into a ball. That defence is poorly suited to a person who can pick up the animal, and the scales themselves have become a commodity. The eight recognised species live in parts of Africa and Asia, where habitat loss and direct exploitation affect them in different combinations.

Eight species, not one interchangeable population

African pangolins include ground-dwelling and tree-climbing forms; Asian species occupy a range of forest, grassland and agricultural mosaics. They feed mainly on ants and termites, using strong claws to open nests and a long sticky tongue to collect prey. Their habitats, movement patterns and exposure to roads or snares differ. A national estimate for one species cannot be used as a proxy for the global group.

The 2025 IUCN-CITES review identifies all eight as remaining at high risk of extinction. It does not supply fresh population totals for each one. Many range states lack repeated field surveys, and secretive nocturnal behaviour makes detection difficult. Researchers may use signs, camera traps, local knowledge, genetic material and market data, but each measures something different. The honest answer to “how many remain?” is often that a robust number is not available.

What the trade rules do

At CITES CoP17 in 2016, all pangolin species were transferred to Appendix I, with the listing taking effect in 2017. Appendix I generally prohibits international commercial trade in wild-caught specimens. It does not, by itself, remove domestic demand, stop every cross-border shipment or guarantee that all countries can detect concealed cargo.

The IUCN-CITES review describes a sharp fall in legal international trade after the Appendix I transfer, but also persistent trafficking and uneven reporting. Between 2016 and 2024, scales accounted for 99% of the confiscated pangolin parts represented in the seizure records covered by the report. That percentage describes the seizure dataset, not the full composition of all illicit trade. A large shipment can represent many animals, and customs records sometimes identify a shipment’s weight without a certain species-level count.

Officials and researchers use seizure events as indicators, not as a direct measure of total poaching. Enforcement campaigns may increase detected seizures even when underlying trafficking is stable; a fall in recorded seizures may reflect weaker detection rather than reduced trade. The report’s estimate of more than half a million represented animals is therefore alarming but incomplete, and should always be presented with its period and method.

Habitat and local pressures remain central

Trafficking is not the only threat. Forest clearing, road construction, agricultural expansion and other land-use changes can break up habitat and make animals easier to encounter. Pangolins are also killed for local consumption in some areas. The 2025 review stresses that legal protection is widespread on paper, while use continues in many range countries. Laws need to be paired with monitoring and conservation measures that fit local conditions.

That means working with communities who live alongside pangolins, improving data collection, and investigating both supply and demand. It also means avoiding a strategy that treats every pangolin range state as identical. Some places may need protected habitat and anti-snaring work; others need stronger port enforcement, careful case reporting or community-led monitoring. Conservation success should be judged by outcomes for wild populations, not only by the number of new rules announced.

Why armour is not a conservation plan

Scales can deter some predators, just as a tortoise shell can protect its owner from certain attacks. Neither can prevent habitat conversion, vehicle collisions or capture by people. The broader Russian article compares several armoured animals; this page concentrates on pangolins because current trade data offer a specific case. The Sumatran rhinoceros faces a different mix of isolation, habitat fragmentation and poaching, illustrating why conservation plans must match each species’ biology.

Trade bans matter, but they are one tool within a larger response. For pangolins, current evidence supports three careful conclusions: illegal trade remains active; seizure records indicate very large detected volumes; and the wild population trend is not known well enough to turn those records into an exact global total. The gap in data is itself part of the conservation emergency.
