The Philippine warty pig has one subspecies associated with the Greater Luzon Faunal Region and another with the Greater Mindanao Faunal Region. Their head hair differs, while many details of the species' diet and behavior remain unknown.
The specialist group describes the Luzon subspecies with a grayish crown tuft and forward-directed fringe. The Mindanao subspecies has a mostly black crest and mane, a whitish crown tuft, and a fringe that is less apparent or absent.
