Visayan Warty Pig (Sus cebifrons) lives in tropical rainforest across Visayan Islands Philippines. It feeds on fruits and roots. Its conservation status is Critically Endangered.
Fascinating facts about the Visayan Warty Pig
- Only six islands ever hosted the Visayan warty pig, but today it clings to two documented populations. The species is endemic to six of the Visayan Islands (Cebu, Negros, Panay, Masbate, Guimaras, and Siquijor), yet it is believed to be extinct in four of the islands in its original native range, with only small surviving populations in Negros and Panay. This razor-thin distribution means any local disturbance can wipe out an entire genetic lineage, pushing the species ever closer to disappearance.
- Visayan warty pigs tend to live in groups of four to six, and their diet mainly consists of roots, tubers, and fruits found in the forest. Since approximately 95% of their natural habitat has been cleared by local farmers who cut down the forest to plant crops, the propensity of the pigs to eat cultivated crops has risen dramatically. This shift brings them into direct conflict with farmers and further shrinking their numbers.
- Piglets are born during the dry months, and each sow usually raises only a handful of young. Visayan warty pig piglets are often seen during the dry season between the months of January and March in their native habitat of the western Visayan Islands. The mean number of piglets is three to four per litter, meaning each female contributes just a few offspring to an already tiny population each year.
- Habitat loss has erased almost the entire range of the Visayan warty pig, and hybridization threatens its genetic purity. The biggest threat to the Visayan warty pig is habitat loss caused by commercial logging and slash-and-burn farming. In total, it is extinct in 98% of its original native range due to loss of forest cover. They are also vulnerable to genetic contamination, as they readily hybridize with feral domestic pigs. To counter this, successful breeding programs at the Rotterdam Zoo for pigs of Negros origin, and at the San Diego Zoo for pigs of Panay origin, keep pure lineages alive for future re-introductions.
- Two pig populations have been evolving apart for millennia. both populations have been physically and genetically isolated since the last ice age (c. 12,000 yrs).

About the Visayan Warty Pig
In the dwindling forests of the Visayan Islands, a creature of unassuming majesty roams, its rugged, wart-encrusted visage a testament to its unyielding resilience. The Visayan Warty Pig moves with a quiet purpose, its stout legs carrying it deliberately through the underbrush as it roots out the forest floor in search of sustenance, its very existence a reminder of the beauty and fragility of this endangered world. As it disappears into the shadows, its grunts and snorts echoing through the trees, we are reminded of the urgent need to preserve this remarkable, yet critically endangered, species.
