Physical Characteristics
The Japanese macaque is sexually dimorphic. Males weigh on average 11.3 kg (25 lb), while females average 8.4 kg (19 lb). Macaques from colder areas tend to weigh more than ones from warmer areas. Male average height is 570.1 mm (22.44 in) and female average height is 522.8 mm (20.58 in). Japanese macaques have short stumps for tails that average 92.51 mm (3.642 in) in males and 79.08 mm (3.113 in) in females. The macaque has a pinkish face and posterior. The rest of its body is covered in brown, greyish, or yellowish hair. The coat of the macaque is well-adapted to the cold and its thickness increases as temperaure decreases. The macaque can cope with temperatures as low as -20°C (-4°F).
Macaques mostly move on all fours. They are semiterrestrial, with females spending more time in the trees and males spending more time on the ground. Macaques are known to leap. They are also great swimmers and have been reported to swim over half a kilometer. The longevity for the macaque averages 6.3 years, (at least for females). However, they have been known to live much longer; males have lived up to 28 years and females up to 32 years.

Famous quotes containing the word physical:
“Not too many years ago, a child’s experience was limited by how far he or she could ride a bicycle or by the physical boundaries that parents set. Today ... the real boundaries of a child’s life are set more by the number of available cable channels and videotapes, by the simulated reality of videogames, by the number of megabytes of memory in the home computer. Now kids can go anywhere, as long as they stay inside the electronic bubble.”
—Richard Louv (20th century)
