gray langurs. Females have a white patch of fur on the inner thigh. It typically lives in troops of nine to ten monkeys.[1] Its diet consists of fruits, shoots and leaves. The species is classified as vulnerable due to habitat destruction and poaching for its fur and flesh, the latter believed to have aphrodisiac properties.[4]

Taxonomy and classification

The classification of the Nilgiri langur has been disputed. Traditionally it has been placed within the genus Trachypithecus based on morphological similarities such as cranial morphology and neonatal pelage color, and within the Trachypithecus vetulus group within Trachypithecus based on a presumed close relationship with the

gray langurs and have thus been reclassified within the genus Semnopithecus.[5][6][7][8][3][9]

Distribution

Kodagu in Karnataka, Kodayar Hills in Tamil Nadu, and many other hilly areas in Kerala and Tamil Nadu. It is also found in Silent Valley National Park of Kerala.[10]
