Home - Guide - Siamang

Located

    The Siamang is located on the island of Sumatra and on
    peninsular Malaysia.  

Diet

    The Siamang is omnivorous; however, the diet consists
    mostly of fresh leaves and fruit.  They will also consume
    nuts, insects, eggs and small vertebrates.

Habitat

    The Siamang can be found in the rainforests, monsoon
    forests and mountian forests of Sumatra and peninsular
    Malaysia.  The Siamang is arboreal - meaning they
    spend most of their lives in the trees.  They travel across
    the trees of the rainforest using a mode of transportation
    called brachiation.  Brachiation is generally used by
    primates when they swing from tree to tree with their
    arms only.  While one arm is holding on to a branch or
    limb, the other arm will be moving toward the next
    branch.  They can carry objects with their feet during this
    maneuver.  The Siamang is also very acrobatic and can
    leap large distances while moving across the rainforest.

Size and Description

    The Siamang ranges from 2.5 - 3 feet in height.  The arm
    span can be 2 - 2.5 times the size of the body.  The
    Siamang can weigh between 18 - 27 pounds.  The coat of
    the Siamang covers most of its body.  It is black and
    consists of long hairs.  The hands and feet are much like
    the hands and feet of other primates except that the
    second and third toes are webbed together.  Having two
    or more digits fused together is defined as being
    syndactylous.  The face resembles that of many other
    primates, but can be distinguished by a large gray or
    pink throat sac.  The throat sac is used for
    communication between Siamangs.  The sounds may
    resemble loud booms or barks, and will be used in
    defending a territory and other activities.  The throat sac
    will inflate while the Siamang makes sounds.   

Reproduction

    Siamangs generally mate for life with one partner.  The
    gestation or pregnancy period is between 7 - 8 months.  
    The female will most often give birth to one offspring.
