The Philippine long-tailed macaque (Macaca fascicularis philippensis) is a subspecies of the crab-eating macaque, known in various Philippine languages as matching/matsing or the more general term unggoy ("monkey").

[citation needed] Like most primates, the Philippine long tailed macaque is omnivorous.

[citation needed] The Philippine long-tailed macaque is found on the Philippine islands of Balabac, Basilan, Biliran, Bohol, Busuanga, Camiguin, Catanduanes, Culion, Leyte, Luzon, northeastern Mindanao, Mindoro, Negros, Panay, Palawan, Samar, and Sibuyan.

[4] Fossils excavated in Palawan were identified as being of the Philippine long-tailed macaque, deer, Palawan bearded pig, Bornean tiger, small mammals, lizards, snakes and turtles.

[5][6] In prehistoric times, the Greater Sunda Islands of Borneo might have been connected to Palawan during the penultimate and previous glacial periods, judging from the molecular phylogeny of murids.
