On Mindanao live 18 tribal Filipino groups. The most well known are the T'boli and the B'laan (or "Bla-an"). The other groups are the Ata, Bagobo, Banwaon, Bukidnon, Dibabawon, Higaunon, Kalagan, Mamanwa, Mandaya, Mangguwangan, Manobo, Mansaka, Subanen, Tagakaolo, Teduray and the Ubo.
Most characteristic of these 'indigenous groups' is that they live in a traditional way, comparable with how the ancestors lived centuries ago
