The most common monkey species found in animal research are the grivet, the rhesus macaque, and the crab-eating macaque, which are either wild-caught or purpose-bred. [66] [67] They are used primarily because of their relative ease of handling, their fast reproductive cycle (compared to apes) and their psychological and physical similarity to ...
The monkey's size differs depending on sex and species. Males from all species can range from 41 to 70 cm (16 to 28 inches) in head and body length, and in weight from 5.5 to 18 kg (12.13 to 39.7 lb). [6] Females can range from a weight of 2.4 to 13 kg (5.3 to 28.7 lb).
The rhesus macaque (Macaca mulatta), colloquially rhesus monkey, is a species of Old World monkey. There are between six and nine recognised subspecies split between two groups, the Chinese-derived and the Indian-derived.
Several Old World monkeys have anatomical oddities. For example, the colobus monkeys have stubs for thumbs to assist with their arboreal movement, the proboscis monkey has an extraordinary nose, while the snub-nosed monkeys have almost no nose at all. The penis of the male mandrill is crimson and the scrotum is lilac; the face is also brightly ...
The male common patas monkey grows to 60 cm (24 in) to 87 cm (34 in) in length, excluding the tail, which measures 75 cm (30 in). Adult males are considerably larger than adult females, which average 49 cm (19 in) in length. [9]
New World monkeys are small to mid-sized primates, ranging from the pygmy marmoset (the world's smallest monkey), at 14 to 16 cm (5.5 to 6.5 in) and a weight of 120 to 190 g (4.2 to 6.7 oz), to the southern muriqui, at 55 to 70 cm (22 to 28 in) and a weight of 12 to 15 kg (26 to 33 lb).
The mandrill is the most sexually dimorphic primate, [22] and it is the largest monkey. [23] Females are less stocky and have shorter, flatter snouts. [19] Males have a 70–95 cm (28–37 in) head-body length and weigh 19–30 kg (42–66 lb) while females have a 55–70 cm (22–28 in) head-body length and weigh 10–15 kg (22–33 lb). [24]
