baby Langur ... langur is the general name given to numerous species of Asian monkeys. The colour of the young, born singly after five to six months’ gestation, differs from that of adults and possibly serves to arouse the protective instincts of the adults. Mothers are protective but allow other females to help care for the young. The gray, or Hanuman, langur of the Indian subcontinent is almost black when newborn and gray, tan, or brown as an adult. found in China, Vietnam and Laos.
