The Javan treeshrew is a small mammal 12–15 centimeters long. It lives in trees in the tropical forests of Java and Sumatra, runs quickly along branches, and feeds on insects and fruits.
The Javan treeshrew differs from other treeshrews by its small size and rare visits to the young. It is important for the forest because it disperses plant seeds with fruits.
Runs fast along branches and catches prey with sharp teeth.
Immature form that undergoes metamorphosis before adulthood.
