Atheris barbouri is a small venomous snake from the viper family. It lives in the mountain forests of Tanzania and feeds mainly on earthworms.
Atheris barbouri differs from other vipers by feeding on worms instead of small mammals and by its terrestrial lifestyle. It helps control the population of invertebrates in mountain forests and serves as an important part of the local nature.
Immature form that undergoes metamorphosis before adulthood.
