Rhesus macaque

Macaca mulatta

Also calledBandar (Hindi/Urdu) · Markaṭa (Sanskrit) · Bāndor (Bengali) · Mihóu 猕猴 (Chinese) · Mono rhesus (Spanish)

The familiar temple and street monkey of northern South Asia and China, with the widest range of any non-human primate. It has shaped modern medicine: the Rh blood factor is named after it, and rhesus monkeys were central to polio vaccine development and early spaceflight.

The rhesus macaque, colloquially rhesus monkey, is a species of Old World monkey in the Macaca genus. There are between six and nine recognised subspecies split between two groups, the Chinese-derived and the Indian-derived. Generally brown or grey in colour, it is 47–53 cm (19–21 in) in length with a 20.7–22.9 cm (8.1–9.0 in) tail and weighs 5.3–7.7 kg (12–17 lb). It is native to South, Central, and Southeast Asia and has the widest geographic range of all non-human primates, occupying a great diversity of altitudes and habitats. Wikipedia

In the old herbals & bestiaries

No plate in the Source Library names this exact species, so these show its closest relatives as the old naturalists drew them: same genus, or the same kind of animal. Click a plate to read the page it came from, with translation.

Marginalia

Monkeys around Hindu temples are fed as associates of Hanuman, the monkey-god of the Ramayana. India banned the export of rhesus monkeys in 1978 after decades of supplying laboratories worldwide.

Curiosity

A rhesus monkey named Albert II became the first primate in space in June 1949, aboard a V-2 rocket launched from New Mexico.
