Philippine long-tailed macaque height of 40–50 cm (16–20 in). It is the size of a domestic cat. Male macaques weigh 4–8 kg, but females only attain 3–4 kg. The Philippine long-tailed macaque is found in all major Philippine island groups (Luzon, Visayas, Mindanao). However, though assessed Near Threatened, it is actually in serious retreat or already extinct in much of its original range. For instance, in Olongapo in Zambales Province (western central Luzon), where a patch of old-growth forest remains, the monkeys have found some refuge; however, they are often road killed, accidentally electrocuted by live wires, and sometimes stoned.

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. However, its full specific
