Semnopithecus entellus:- These langurs are largely gray (some more yellowish), with a black face and ears. Externally the various species mainly differ in the darkness of the hands and feet, the overall color and the presence or absence of a crest. There are also significant variations in the size depending on the species, but the head-and-body length of males is typically up to 75 cm (30 in) and that of females is 65 cm (26 in). Their tail is always longer than their body. Langurs from the southern part of their range are smaller than those from the north. At 26.5 kg (58 lb), the heaviest langur ever recorded was a male Nepal gray langur.
Langurs mostly walk quadrupedally and spend half their time on and the ground and the other half in the trees. They will also make bipedal hops, climbing and descending supports with the body upright, and leaps. Langurs can leap 3.7-4.6 m (12.0-15.0 ft) horizontally and 10.7-12.2 m (35-40 ft) in descending
