Philippine long-tailed macaque Philippine long-tailed macaque 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"). It is endemic in the Philippine forests and woodlands, but especially in the mangrove forests of western central Philippines— particularly in Palawan, the Visayas, and Mindanao. The names "M. f. philippinensis" or even "M. f. philippinenesis" have also been used, but arise from orthographical error. The Philippine long-tailed macaque has a reddish-brown coat. Its tail has an average length of 50 cm to 60 cm. It can reach a
Arunachal macaque and 3500 m above sea level, making it one of the highest-dwelling primates. It belongs to the "M. sinica" species-group of macaques, along with the Assamese macaque ("M. assamensis"), the Tibetan macaque ("M. thibetana"), the bonnet macaque ("M. radiata") and the toque macaque ("M. sinica"). The Arunachal macaque is apparently physically similar to the Assam and Tibetan macaques, while genetically closely related to the bonnet macaque of southern India. This is probably the result of convergent evolution, where organisms evolve similar physical features due to similar environmental selection pressure, while genetically they may have different origins.
