The White-Bellied Pangolin: Africa’s Most Widespread Tree-Dwelling Pangolin

High in the canopy of a West African rainforest, a small, scale-covered mammal grips a branch with its prehensile tail, probing a crevice in the bark with a tongue that extends far beyond the length of its head. This is the white-bellied pangolin (Phataginus tricuspis), also known as the tree pangolin — the smallest and most widespread of Africa’s four pangolin species. Despite occupying the largest range of any African pangolin, stretching from Senegal to western Kenya, the white-bellied pangolin is classified as Endangered by the IUCN Red List, driven toward decline by the same forces that threaten pangolins across the globe: illegal trafficking, bushmeat hunting, and habitat destruction.

For conservationists in southern Africa working to protect Temminck’s ground pangolin (Smutsia temminckii), the white-bellied pangolin’s story offers critical insight. The trafficking networks that funnel African pangolin scales to Asian markets draw heavily from Phataginus tricuspis populations, and what happens to the tree pangolin in the forests of West and Central Africa reverberates through the entire global pangolin trade.

Taxonomy and Classification

The white-bellied pangolin belongs to the genus Phataginus, which it shares with the black-bellied pangolin (Phataginus tetradactyla). Together, these two species represent Africa’s arboreal pangolins, distinct from the ground-dwelling Smutsia genus that includes Temminck’s ground pangolin and the giant ground pangolin. Its specific name, tricuspis, refers to the three-pointed tips of its scales — a distinguishing morphological feature.

Physical Description

The white-bellied pangolin is the smallest of Africa’s pangolins, with adults typically weighing between 1.5 and 3 kilograms and measuring 30 to 44 centimetres in head-body length. The tail adds another 35 to 50 centimetres and is strongly prehensile, capable of supporting the animal’s entire body weight as it hangs from branches. The dorsal surface is covered in overlapping keratinous scales ranging from brown to olive-brown, while the underside — the belly, inner limbs, and face — is covered in pale or whitish skin, giving the species its common name.

Each scale bears three distinct cusps at the tip, unique to this species among African pangolins. The forelimbs carry strong, curved claws adapted for climbing and tearing open insect nests.

Habitat and Range

The white-bellied pangolin has the most extensive geographic range of any African pangolin. It is found across West and Central Africa, from Senegal and Guinea-Bissau in the west, through the Gulf of Guinea nations, across the Congo Basin, and eastward to western Kenya and north-western Tanzania. The range extends south through the Democratic Republic of the Congo into northern Angola and northern Zambia, spanning more than 15 countries.

The tree pangolin inhabits tropical moist lowland forests, including primary and secondary rainforest, swamp forests, and forest-savanna mosaics. It is predominantly arboreal, spending most of its active time in the canopy. During the day, it rests in tree hollows, dense vegetation tangles, or occasionally in ground-level burrows. The species can tolerate some habitat degradation and has been recorded in plantations and farmed landscapes adjacent to forest, though it remains dependent on tree cover for foraging and shelter.

Diet and Behaviour

Like all pangolins, the white-bellied pangolin feeds almost exclusively on ants and termites. It locates prey using its acute sense of smell, then uses its elongated, sticky tongue — which can extend approximately 25 centimetres — to extract insects from nests in bark, rotting wood, and arboreal termitaria. Unlike ground-dwelling African pangolins, the tree pangolin focuses on arboreal ant and termite colonies found in the forest canopy.

The white-bellied pangolin is strictly nocturnal and solitary. Outside of brief mating encounters and the period when a mother carries her single offspring on her tail, these animals live and forage alone across individual home ranges that overlap with those of neighbouring individuals.

Females give birth to a single offspring after a gestation period estimated at approximately 150 days. The newborn weighs around 100 to 150 grams and has soft scales that harden over the first few days of life. The young pangolin rides on the base of its mother’s tail and begins accompanying her on foraging trips at around three months of age. When threatened, the white-bellied pangolin curls into a tight ball, relying on its armoured scales for protection — effective against natural predators but rendering the animal defenceless against human hunters, who simply pick up the rolled animal.

Threats

Bushmeat hunting and local trade

Across much of West and Central Africa, the white-bellied pangolin is the most commonly encountered pangolin in bushmeat markets. Studies in Cameroon, Nigeria, Gabon, and the Democratic Republic of the Congo have consistently identified Phataginus tricuspis as the most frequently traded pangolin species. In many rural communities, pangolin meat is considered a delicacy and the scales are used in traditional medicine. This sustained local demand represents a significant threat that operates independently of international trafficking.

International trafficking

Since all eight pangolin species were listed on CITES Appendix I in 2017, banning international commercial trade, seizures have revealed the industrial scale of trafficking. The white-bellied pangolin is one of the most heavily trafficked pangolin species globally. Multi-tonne shipments of scales seized in transit between Africa and Asia have been traced primarily to West and Central African source countries within the range of Phataginus tricuspis.

Habitat loss

Tropical deforestation across the species’ range continues to reduce and fragment essential forest habitat. Agricultural expansion, logging, and mining are the primary drivers. While the tree pangolin can tolerate some degradation, large-scale clearance eliminates the arboreal corridors and tree hollows essential for foraging and reproduction.

Conservation Status and Efforts

The IUCN uplisted the white-bellied pangolin to Endangered in 2019, from its previous Vulnerable classification, reflecting accelerating population decline driven by overexploitation. The 2017 CITES Appendix I listing provides the international legal framework to combat cross-border trade, though enforcement remains a persistent challenge.

Conservation efforts operate at multiple levels. The IUCN SSC Pangolin Specialist Group coordinates research and conservation planning across all eight species. In West and Central Africa, organisations work with communities and governments to reduce hunting pressure, improve law enforcement, and gather ecological data. Community-based programmes that provide alternative livelihoods to former hunters have shown promise, echoing the community-centred approaches used to protect Temminck’s ground pangolin in South Africa.

South Africa’s experience with pangolin conservation — through organisations like the African Pangolin Working Group and the Pangolert hotline — demonstrates that rapid community response and coordinated law enforcement can make a measurable difference. These models are directly relevant to conservation strategies for the white-bellied pangolin across its West and Central African range.

Captive breeding of pangolins remains extremely difficult. The white-bellied pangolin has one of the poorest survival records in captivity of any mammal, with most individuals dying within months due to stress, dietary deficiencies, and susceptibility to disease. This means that wild population protection, rather than captive programmes, remains the only viable path to species survival.

Why the White-Bellied Pangolin Matters

As a specialised insectivore, the white-bellied pangolin plays an important ecological role in regulating ant and termite populations in tropical forest ecosystems. Beyond ecology, the species serves as a barometer for the broader pangolin trafficking crisis: because Phataginus tricuspis is the most commonly trafficked African pangolin, its population trajectory signals the effectiveness — or failure — of international anti-trafficking measures. Protecting the white-bellied pangolin is inseparable from the fight to save all eight pangolin species from the exploitation that has made them the most trafficked mammals on Earth.
