The Kashmir gray langur (Semnopithecus ajax) is an Old World monkey, one of the species of langurs. This, like other gray langurs, is a leaf-eating monkey. It has been reported from northern India west into Pakistani Kashmir and in Nepal, but evidence indicates it only occurs within a single valley in Himachal Pradesh, India. A small population is also found in Manshi Wildlife Sanctuary and Sharan forest in Kaghan Valley, KPK, Pakistan. Alloparental care occurs in Kashmir's gray langur for up to 5 months. Males are usually protective of infants, but infanticide occasionally occurs.
