The red viper is a small venomous snake with a thick body and reddish-brown coloration. It lives in the mountainous regions of South Africa and hunts from ambush.
The red viper differs from other vipers by its very small size and bright reddish coloration, which helps it hide among rocks. It plays an important role in nature by controlling the population of small animals.
Immature form that undergoes metamorphosis before adulthood.
