Also known as the Silvery lutung or Silvery langur. Mainly
arboreal, living in coastal, mangrove, and riverine forests in
Peninsular Malaysia, Sumatra, and Borneo. The young are born
with orange fur and with white hairless skin on the face, hands,
and feet. The skin rapidly changes to the dark adult colour but
the fur does not reach the adult pattern for three to five
months after birth. Found across Borneo and Sumatra as well as
in parts of the south-western Malay peninsula, the Natuna
Islands, and other nearby islands. It inhabits mangrove swamps
and nearby forest regions, and generally avoids traveling far
from coasts or rivers.
