Bornean Grey Langur

Hose's langur has grey-ish fur all over their bodies except for white tuffs of fur on their head that forms a point at the top of the head and points on either sides of their face. Also, their grey-ish fur turns a darker shade then into black fur on their backs, hands, feet and on their face. The black fur forms a "bandit mask" over their pink skin, much like a raccoon.

Hose's langur is commonly found in the northern and eastern regions of Malaysia as well as the northern part of Borneo. They are most likely to be found in coastal regions with forests. These forests regions called dipterocarp forests are known for their tall trees, in which the Hose's langur spends its entire life. The Hose's langur's territory is small spanning no larger than 0.14 square miles. It has been observed that they rarely leave this small area.

Hose's langur primarily eat leaves but have been observed to sometimes eat fruits. Because of their high cellulose diet, they have a four chambered stomach, similar to a cow, giving them a "pot-belly" like body shape. They also have been observed in rare occasions to climb down from the canopy of the forest to eat mud at mineral springs. When they eat this mud its minerals form what's called a bezoar stones in their stomachs. In some cultures, these stones are believed to have a medicinal effect for humans.
