Nicobar long-tailed macaque a defined captive breeding programme were deficient. 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
Rhesus macaque significance because the macaque is used as an experimental model of the human immune system. In humans, the preferentially expressed antigen of melanoma (PRAME) gene family is expanded. It is actively expressed in cancers, but normally is testis-specific, possibly involved in spermatogenesis. The PRAME family has 26 members on human chromosome 1. In the macaque, it has eight, and has been very simple and stable for millions of years. The PRAME family arose in translocations in the common mouse-primate ancestor 85 million years ago, and is expanded on mouse chromosome 4. DNA microarrays are used in macaque research. For example,
