Rhesus Macaque, Jaigarh Fort
|[Note Guidelines] Photographer's Note|
|This photograph of wild monkey is shot at Jaigarh Fort, Jaipur. It was enjoying dry coconut when I approached it and took this close up against Fort's boundary wall. I have cropped the image and made it squarish to get maximum body area enlarged as an effects of.|
The Rhesus Macaque (Macaca mulatta), often called the Rhesus Monkey, is one of the best known species of Old World monkeys. Inhabiting arid, open areas, the Rhesus Macaque may be found in grasslands, woodlands, and in mountainous regions up to 2,500 metres in elevation. They are regular swimmers, babies as young as a few days old can swim and adults are known to swim over a half mile between islands, but are often found drowned in small groups where their drinking waters lie.
Females cycle similar to humans with menstrual cycles of around 28 days.
Mating is not confined to a specific season. Gestation may last from 135-194 days. Females are mature by three years of age, and males at four. The typical lifespan of a rhesus monkey in captivity is approximately 15–20 years for males and 20–25 years for females. These monkeys rarely live beyond 15 years of age in the wild.
The Rhesus Macaque is noted for its tendency to move from rural to urban areas, coming to rely on handouts or refuse from humans. It has become a pest in some areas, perceived as a possible risk to public health and safety.
A diurnal animal, the Rhesus Macaque is both arboreal and terrestrial; it is mostly herbivorous and feeds on leaves and pine needles, roots, and the occasional insect or small animal. The monkey has specialized pouch-like cheeks, allowing it to temporarily hoard its food. Occasionally, it has been known to consume human flesh.
According to Melnick et al, "The rhesus monkey has the widest geographic ranges of any nonhuman primate," occupying a great diversity of altitudes throughout Central, South, and Southeast Asia.
Comparing the macaque and human genome, which diverged 25 million years ago and had 93% identity, further identified evolutionary pressure and gene function. Surprisingly, some normal gene sequences in healthy macaques and chimpanzees cause profound disease in humans. For example, the normal sequence of phenylalanine hydroxylase in macaques and chimpanzees is the mutated sequence responsible for phenylketonuria in humans. So humans must have been under evolutionary pressure to adopt a different mechanism.
In 1940, Karl Landsteiner and Alexander S. Wiener reported a serum that also reacted with about 85% of different human red blood cells. This serum was produced by immunizing rabbits with red blood cells from Rhesus macaque. The antigen that induced this immunization was designated by them as Rh factor "to indicate that rhesus blood had been used for the production of the serum."

Nice close portait of a Rhesus Macaque, a species that has been responsible for saving many human lives!
The POV and posture as it eats a fruit is well presented with fine sharpness and colours.
Thanks and kind regards,
