Pangolin

The pangolin (Manis temminckii), also known as the ground pangolin or Cape pangolin, is a unique, scale-covered mammal found across sub-Saharan Africa and one of eight pangolin species worldwide. Often called the world's most trafficked mammal, pangolins are in severe crisis, with all eight species threatened by illegal poaching for their scales, which are falsely believed to have medicinal properties in parts of Asia, and for their meat. Despite superficially resembling reptiles or armadillos, pangolins are actually mammals more closely related to carnivores such as dogs and cats. They are extraordinary evolutionary marvels, representing an entirely unique lineage of life with no close living relatives.

The pangolin's most distinctive feature is its armor of overlapping keratin scales, the same material as human fingernails, which covers its entire body except for the soft underside, face, and inner limbs. When threatened, a pangolin curls into a tight ball, protecting its vulnerable belly with its tough, sharp-edged scales that can even cut the gums of predators attempting to bite it. The ground pangolin has a stocky body, short, powerful legs with strong claws for digging, and a long, tapering tail. Its tongue, which can extend up to 40 cm — longer than its own head — is covered in sticky saliva and stored in a sheath that extends all the way into the chest cavity when retracted.

Pangolins are predominantly nocturnal and solitary animals, spending their days in burrows or hollow trees and emerging at night to forage for ants and termites. They locate insect colonies primarily by smell, as they have poor eyesight but an excellent sense of smell. When feeding, a pangolin uses its powerful foreclaws to break open hard termite mounds and ant nests, then inserts its extraordinarily long tongue to collect insects. During the day, their burrows serve as thermoregulatory retreats. Males and females only associate during the brief breeding season. Their most famous defense is rolling into an armored ball, which is highly effective against natural predators but unfortunately makes them easy for human poachers to simply pick up.

Pangolins are obligate myrmecophages, meaning they eat exclusively ants and termites. A single pangolin may consume up to 70 million insects per year, making them extraordinarily important for controlling insect populations. They do not have a fixed territory for feeding but instead move between areas, excavating termite mounds and ant colonies with their powerful claws and feeding with their long sticky tongues. They have been observed to carefully time their foraging to avoid army ant columns, which can pose a danger even to pangolins. Their stomach contains swallowed stones that help mechanically break down the chitin exoskeletons of their insect prey.

Pangolins have a very low reproductive rate, with females giving birth to a single offspring per year after a gestation period of approximately 139 days. The newborn pangolin, called a pangopup, is born with soft, flexible scales that harden over the first few days of life. The mother carries the young on her back or tail, and if threatened, she curls around the pup to protect it. Young pangolins begin foraging with their mothers after a few weeks and are weaned at around 3 to 4 months, becoming fully independent at about 6 months. Their slow reproductive rate makes pangolin populations extremely slow to recover from population declines.

Pangolins face an almost entirely human-caused existential crisis. They have been hunted for centuries as a food source in parts of Africa and Asia, but the modern pangolin trade is driven primarily by demand for scales used in traditional Chinese medicine and pangolin meat as a luxury food item in China and Vietnam. The trade is largely illegal but deeply entrenched in organized criminal networks. Conservation efforts include strengthening law enforcement and anti-poaching measures, reducing demand through education campaigns, and developing captive breeding programs — though pangolins are notoriously difficult to keep in captivity due to specialized dietary needs and high stress susceptibility. Indigenous communities in parts of Africa are being engaged as conservation partners to monitor and protect pangolins in their territories.
