Bonnet macaque Bonnet macaque The bonnet macaque also known as zati ("Macaca radiata") is a macaque endemic to southern India. Its distribution is limited by the Indian Ocean on three sides and the Godavari and Tapti Rivers along with a related competing species of rhesus macaque in the north. Land use changes in the last few decades have resulted in changes in its distribution boundaries with the rhesus macaque, raising concern for its status in the wild. This Old World monkey is a diurnal animal. It is 35–60 cm long plus a tail of 35–68 cm. Males weigh 5.5 to 9.0 kg,
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
