Long-Tailed Pangolin

The long-tailed pangolin is a small, tree-dwelling pangolin of the forests of West and Central Africa. Covered in protective overlapping scales, it has an exceptionally long tail used to grip branches. It feeds on ants and termites and curls into a ball when threatened.

The long-tailed pangolin (Phataginus tetradactyla) is unusual among pangolins for being predominantly diurnal or cathemeral, rather than strictly nocturnal like most of its relatives. This is likely linked to its highly arboreal lifestyle, spending the vast majority of its life in the forest canopy where it forages, rests, and travels using its extraordinarily long, prehensile tail—proportionally the longest tail of any pangolin species, accounting for roughly 60-70% of its total body length. This tail acts as a fifth limb, gripping branches securely and allowing the animal to move confidently through dense vegetation, often over rivers, swamps, and flooded forest habitats it favors.

Long-tailed pangolins are solitary animals, coming together only briefly to mate. They communicate primarily through scent marking, using secretions from specialized anal glands to mark territory and signal reproductive status to potential mates, as well as through tactile cues during rare social encounters. Vocalizations are minimal, generally limited to soft hisses or puffing sounds when threatened. Home ranges are not extensively well-documented due to the species’ cryptic canopy-dwelling nature, but individuals appear to maintain overlapping arboreal ranges within suitable forest patches.

Like all pangolins, this species’ primary defensive adaptation is curling into a tight ball when threatened, using its overlapping keratin scales as armor to protect its vulnerable underside. This behavior, combined with its arboreal habits, helps it avoid many natural predators. It is also capable of climbing down to swim across watercourses when necessary, a trait less common among other pangolin species.

As a specialized insectivore, the long-tailed pangolin feeds almost exclusively on ants and termites, using its long, sticky, worm-like tongue—which can extend beyond the length of its own body when fully retracted into a special abdominal sheath—to extract prey from nests, bark crevices, and arboreal insect colonies. It forages primarily in trees, using its sharp, curved foreclaws to tear open ant nests and rotting wood, then rapidly flicking its tongue in and out to capture insects, which are swallowed whole and ground down in a muscular, gizzard-like stomach aided by ingested small stones and keratinous spines.

This species lacks teeth entirely, relying instead on this mechanical digestion process. Its metabolic rate is notably low compared to similarly sized mammals, an adaptation that conserves energy given the relatively low caloric yield of an ant-and-termite diet. Long-tailed pangolins obtain most of their water needs from their prey and are not commonly observed drinking free-standing water, though they inhabit swampy, humid forest environments where moisture is abundant. There is limited evidence of significant seasonal dietary shifts, as ant and termite colonies remain relatively available year-round in their tropical forest range.

Long-tailed pangolins are believed to be polygynous or promiscuous breeders, with males seeking out receptive females via scent trails during a breeding season that is not sharply defined and may occur year-round in suitable tropical conditions. Mating encounters are brief, after which males and females separate and resume solitary lives. Gestation is estimated at around 135-150 days, though precise data remains limited due to the species’ elusive nature and the difficulty of studying it in the wild.

Females typically give birth to a single offspring, which is born with soft, pale scales that harden within the first few days of life. The young pangolin clings to the base of its mother’s tail as she moves through the canopy, a distinctive form of parental transport. Maternal care is extensive, with weaning occurring at approximately three months, though the juvenile may remain with its mother for several months afterward. Sexual maturity is reached at approximately two years of age, though exact timelines vary based on limited field and captive studies.

The long-tailed pangolin faces severe threats primarily driven by illegal poaching for the international wildlife trade, where its scales are trafficked—largely to Asian markets—for use in traditional medicine, and its meat is consumed as bushmeat in parts of its West and Central African range. Pangolins as a group are considered the most illegally trafficked mammals in the world, and this species has seen dramatic population declines as a direct result of commercial and subsistence hunting pressures, exacerbated by improved access to previously remote forest areas via logging roads.

Habitat loss and fragmentation from deforestation, agricultural expansion (notably oil palm plantations), and logging further compound these pressures by degrading the swampy, lowland forest habitats this species depends on. Natural predators include large raptors, big cats, and snakes, though these pose far less risk than human-driven threats. Conservation initiatives include the species’ listing under CITES Appendix I (banning international commercial trade), habitat protection efforts within protected areas across its range, and ongoing research and anti-trafficking enforcement supported by organizations such as the IUCN Pangolin Specialist Group, though enforcement remains inconsistent across much of its range.

• Longest Tail Among Pangolins: The long-tailed pangolin possesses the longest tail relative to body size of all eight pangolin species, with up to 47 caudal vertebrae—more than any other mammal.
• Diurnal Outlier: Unlike most pangolins, which are strictly nocturnal, this species is often active during the day, an unusual trait tied to its arboreal foraging strategy.
• Tongue Longer Than Its Body: Its tongue attaches near the pelvis and last pair of ribs rather than the throat, allowing it to extend to remarkable lengths for insect extraction.
• Living Armor: Pangolin scales are made of keratin, the same protein found in human hair and nails, and make up roughly 20% of the animal’s total body weight.
• Toothless Hunter: With no teeth at all, it relies on a muscular, gravel-lined stomach to grind up ants and termites.
• Champion Swimmer: Despite being arboreal specialists, long-tailed pangolins can swim competently across rivers and flooded forest sections.
• World’s Most Trafficked Mammal Group: Pangolins, including this species, are estimated to account for up to 20% of all illegal wildlife trade by volume globally.
