The Japanese macaque (Macaca fuscata), also known as the snow monkey, is a terrestrial Old World monkey species that is native to Japan. Colloquially, they are referred to as 'snow monkeys' because some live in areas where snow covers the ground for months each year – no other non-human primate lives further north, nor in a colder climate. Individuals have brownish grey fur, pinkish-red faces, and short tails. Two subspecies are known. 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. The average height for males is 57.0 cm (22.4 in), while the average female height is 52.3 cm (20.6 in). The size of their brain is approximately 95 g (3.4 oz). Japanese macaques have short stumps for tails that average 92.5 mm (3.64 in) in males and 79.1 mm (3.11 in) in females. The macaque has a pinkish face and posterior. The rest of its body is covered in brown or greyish hair. The coat of the macaque is well-adapted to the cold and its thickness increases as temperatures decrease. The macaque can cope with temperatures as low as −20 °C (−4 °F). (Source: Wikipedia.org, CC BY-SA)
