Nicobar long-tailed macaque Nicobar long-tailed macaque The Nicobar long-tailed macaque ("Macaca fascicularis umbrosa", popularly known as the Nicobar monkey) is a subspecies of the crab-eating macaque ("M. fascicularis"), endemic to the Nicobar Islands in the Bay of Bengal. This primate is found on three of the Nicobar Islands—Great Nicobar, Little Nicobar and Katchal—in biome regions consisting of tropical and subtropical moist broadleaf forests. The Nicobar long-tailed macaque has brownish to grey fur, with lighter colouration on its undersides. Its face is pinkish-brown, with white colour spots on its eyelids. Infants are born with a dark natal coating, which lightens as they reach maturity,
Crab-eating macaque and "M. f. condorensis" is vulnerable. All other subspecies are listed as data deficient and need further study; although recent work is showing "M. f. aurea" and "M. f. karimondjawae" need increased protection. One concern for conservation is, in areas where "M. fascicularis" is not native, their populations need to be monitored and managed to reduce their impact on native flora and fauna. The genome of the crab-eating macaque has been sequenced. On 24 January 2018, scientists in China reported in the journal "Cell" the creation of two crab-eating macaque clones, named "Zhong Zhong and Hua Hua", using the complex
