By 9 months of age infants change to the gray-black color of adults. Female head and body length in this species is 425-595 mm and tail length varies from 635-813 mm. Females weigh approximately 4.994 to 8.626 g. Female head and body length is 420-675 mm and tail length is 570-790 mm. Males weigh around 6.129 to 9.080 g. The spectacled langur adult brain weighs 67.6 g.
Spectacled langurs live in primary forest (mature and Untouched), secondary forest (regenerated), Lowland forest (altitudes below 1 km) as well as submontane and montane forest up to 1.828 m. Spectacled langurs are arboreal and quadrupedal. Spectacled langurs travel 0.95 miles per day on average.
Gestation in spectacled langurs is approximately 150 days. One observational study of a single captive male spectacled langur characterized the mother-infant relationship throughout the first year of life. Due to limited study, the lifespan of wild-spectacled langurs is unknown.
