Philippine warty pigs usually have black or dark brown fur, as well as recognizable white tufts on the side of their lower jaw (the gonion).

Male pigs have four facial "warts", tusks, and gonial tufts which are larger and yellower than those of the females.

Specifically, the range of Philippine warty pigs included Luzon, Biliran, Samar, Leyte, Mindoro, Mindanao, Jolo, Polillo, Catanduanes, and possibly other islands.

In April 2022, a Philippine warty pig was documented by a Department of Environment and Natural Resources (DENR) team while climbing Mount Apo.

[2] Usage of camera traps has suggested that the pigs prefer open, as opposed to canopied, habitat areas.

[2] Little is known about the pigs' reproduction; however, in general, Suidae have between one and twelve babies in a den, which the piglets leave after about ten days.

Genetic pollution of the Philippine warty pig populations is a major problem, as is hybridization between the two species.
