A Surprising Scientific Rediscovery

Nearly nine decades after it was last documented by the scientific community, the Bangka slow loris—one of the world's only venomous primates—has been officially rediscovered in Indonesia. Researchers revealed that more than 90 individuals of the elusive species were recorded across various locations on Bangka Island between 2015 and 2025.

Previously thought to have vanished entirely after its last official sighting in 1937, the nocturnal, tree-dwelling primate was found living remarkably close to human settlements. Local encounters included sightings in backyards, alongside rural roads, and even clinging to overhead power lines.

"This rediscovery offers vital hope that other species believed to be extinct might still survive in regions that scientists have not extensively studied for decades," said study author Timon Glaw, emphasizing the unexpected resilience of the population.

Unique Biology and Defensive Mechanisms

Measuring roughly 10 inches on average, the Bangka slow loris is notably smaller than its relative, the Sumatran slow loris. Its most defining characteristic is its potent defense mechanism: the animal activates its toxic venom by licking a specialized gland located on its inner arm.

While the toxin is primarily utilized during territorial grooming and interactions with other members of its species, it poses a severe health risk to humans, capable of inducing dangerous allergic reactions, including anaphylactic shock.

Despite these evolutionary defenses, the primates have proven vulnerable to modern infrastructure. Numerous individuals recorded during the recent surveys were found injured, having suffered severe shocks from electrical wiring or attacks from domestic animals.

Conservation Challenges Ahead

Local wildlife organizations have stepped in to address the immediate threats facing the species. The Alobi Wildlife Rescue Centre successfully recovered multiple injured animals, rehabilitating and safely releasing 86 of them back into their natural habitats.

However, conservationists warn that the long-term survival of the Bangka slow loris remains heavily threatened. Langka Sani, Director of the Alobi Wildlife Rescue Centre, highlighted that the primates' natural habitats have severely diminished due to rampant illegal tin mining and large-scale land clearing for oil palm plantations.

Currently classified as critically endangered on the International Union for Conservation of Nature's (IUCN) Red List, researchers stress that merely confirming the animal's survival is only the first step. Experts are calling for comprehensive, long-term conservation strategies encompassing dedicated habitat protection, ongoing population surveys, and strict environmental enforcement to prevent the species from slipping into permanent extinction.
